Description

Technical Field

[0001] This invention relates to the fields of agricultural, forestry, and environmental protection machinery and equipment, and in particular to a fully automatic plant transplanting machinery and equipment. Background Art

[0002] Pot transplanting refers to a planting method where crop seeds are planted in nutrient-rich pots to cultivate seedlings. Once the seedlings reach a certain age or size, they are transplanted to the field or other planting environments to mature. Currently, there are three pot transplanting methods on the market: one is plastic plug tray transplanting. This method uses plastic plug trays with 50 to 100 holes. Soil is filled into the holes, and seeds are planted for seedling cultivation. After the seedlings reach a certain age or size, they are transplanted to the field. This method is now semi-mechanized. The disadvantage of this method is that due to the small hole volume and limited soil usage, seedlings cannot be too large. It is mostly used for pot transplanting of fibrous-rooted crops such as corn, garlic, peanuts, and ginger. Another method is paper cup transplanting. This transplanting method involves using biodegradable fiber paper cups strung together at regular intervals with rope, filling them with soil to form paper pots, planting seeds in these pots, and then using a machine to transplant the seedlings from the paper pots into furrows, finally covering them with soil to complete the transplanting. The disadvantages of this method are the high cost of making the pots, the slow degradation of the paper fibers, and the potential damage to the soil. The third transplanting method is nutrient pot seedling transplanting. This method uses soil containing various nutrients to form clods of a certain size (commonly called "nutrient pots"), planting seeds in them for seedling cultivation, and then transplanting the seedlings to the field or other planting environments after they have grown to a certain size. Because nutrient pots contain a large amount of soil, they can cultivate seedlings of various sizes, making them suitable for the cultivation and transplanting of all crops, flowers, and trees, and causing no soil pollution. The disadvantages of this method are the high labor intensity and the lack of suitable transplanting machinery, currently limiting its application to small-scale manual transplanting and hindering its widespread adoption. This invention is a fully automatic seedling transplanter in nutrient pots, which is highly efficient and automated, and can solve the problem of large-scale transplanting of seedlings in nutrient pots. Summary of the Invention

[0003] The main technical problem solved by this invention is to provide a fully automatic seedling transplanter in nutrient pots, which can solve the problem of large-scale transplanting of seedlings in nutrient pots. Attached Figure Description

[0010] The embodiments are further described in detail below with reference to the accompanying drawings.

[0011] 1. To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a fully automatic nutrient pot seedling transplanter is provided, characterized in that it includes a control system (1), a power and walking system (2, 2-1, 2-2, 2-3, 2-4, 2-5, 2-6, 2-7, etc.), a chain-type seedling storage tray system (3, 3-1, 3-2, 3-3, etc.), a pot seedling conveying control and implementation system (4-1, 4-2, 4-3, 4-4, 4-5, etc.), a trenching system (5-1, 5-2, etc.), and a pot clamp and soil covering system (6-1, 6-2, 6-3, 6-4, 6-5, 6-6, 6-7, 6-8, 6-9, 6-10, 6-11, etc.) for the fully automatic nutrient pot seedling transplanter. This machine can automatically plant seedlings in nutrient pots. It is available in single-row (small), double-row (basic), and multi-row (large) configurations. It features ditching and soil-breaking functions, seedling storage and automatic conveying, adjustable row and plant spacing, and soil mounding for the seedlings. No manual feeding or pre-leveling of the land is required, and no residue is left behind. This machine is not limited to agricultural seedling transplanting; it is also suitable for planting flowers, grass, and trees in urban parks and along roadsides, as well as in wastelands and deserts.

[0012] 2. The aforementioned fully automatic seedling transplanter in nutrient pots includes a control system, power system, and walking system comprising an engine (2-1), a gearbox (2-5), a frame (2-2), a support frame (2-7), a control device (1), a transmission device, a walking mechanism (2-4), and a steering device, which provide stable and reliable power, machine speed, and appropriate rotational speeds for each mechanism. The control device enables the machine to move forward, backward, and turn, as well as start and stop the movement of each mechanism. The control device includes a transmission clutch control handle (1-4), a throttle control handle, a forward and backward control handle (1-6), a steering control handle (1-3), and a hydraulic multi-way valve (1-5). The hydraulic multi-way valve (1-5) controls the lifting and lowering of the trenching mechanism and the pot clamp. Both the trenching mechanism and the pot clamp have clutches, allowing them to stop operating when rising and start operating when falling.

[0013] 3. The fully automatic seedling transplanter described above, wherein the chain-type seedling storage tray system (3) mainly consists of a seedling storage tray frame, sprockets, shafts, ratchet pawls, seedling storage tray chains (3-2), L-shaped plates (3-1), and hydraulic cylinders (3-3). Two shafts are fixed on the seedling storage tray frame, wherein the drive shaft is equipped with sprockets, ratchet pawls, and driven shafts are equipped with sprockets. Two curved plate chains are installed on the sprockets of the two shafts. All L-shaped plates are fixed to the two curved plate chains with bolts at both ends, and hundreds of seedlings in seedling pots can be stored on them. To ensure smooth seedling transport, the seedling storage tray is inclined at a 5° angle to the horizontal plane along the length of the L-shaped plate. The working process of the system is as follows: the hydraulic cylinder pushes the main shaft to rotate a certain angle each time, so that the entire seedling tray moves forward one discharge position, realizing the transport of a row of seedlings.

[0014] 4. The above-mentioned fully automatic nutrient pot seedling transplanter, wherein the pot seedling conveying control and actuation system consists of a swing arm, a half-sprocket and ratchet (4-2), a rotary valve lever, a hydraulic rotary valve, a hydraulic cylinder, a pulley, a pot seedling conveyor belt (4-4), an action chain, a tension spring, an anti-tipping frame (4-1), and a pot pushing frame (4-3). Its specific structure is as follows: ① The swing arm and ratchet are fixed on the same half-sprocket. The half-sprocket and the ratchet are loosely fitted on the same shaft. The half-sprocket and the sprocket on the pot seedling conveyor belt pulley shaft are connected by a chain. A one-way bearing is installed between the pot seedling conveyor belt pulley and the shaft. When the pulley shaft swings, the conveyor belt can only move in one direction. Several parameters, such as the swing angle of the swing arm, the diameter of the pulley, and the tooth ratio of the two sprockets, determine each swing of the swing arm, ensuring that the pot seedling conveyor belt and the pot seedlings on it can only move forward a distance equivalent to the diameter of the pot. ② The rotary valve lever is fixed to a ratchet. The number of ratchet teeth is equal to the number of seedlings stored on an L-shaped plate. When the ratchet rotates one revolution, the rotary valve lever pulls the hydraulic rotary valve once, and the hydraulic cylinder actuates once. ③ There are three conveyor belts for each seedling: two vertically and one horizontally. All three conveyor belts and pulleys are mounted on an L-shaped belt support plate. The L-shaped belt support plate is installed with its length at a 5° angle to the horizontal plane, with the outer side higher than the inner side, so that the seedlings move from high to low. The width of the L-shaped belt support plate is at a 20° angle to the horizontal plane, with the front lower than the back, so that the seedlings move from high to low when pushed onto the L-shaped belt support plate. Two pulleys are mounted at both ends of the L-shaped belt support plate in the horizontal and vertical directions. Two conveyor belts are mounted on the two vertical pulleys, with a gap of more than 20 mm between the two conveyor belts, which is the movement channel for the anti-tipping support rod. The movement of the vertical and horizontal conveyor belts is driven by a pair of meshing bevel gears between the two pulley shafts. ④ Both the anti-tipping frame and the pot-pushing frame are swing-rod structures. The anti-tipping frame supports the tilted pots in the front row of the seedling storage tray to prevent them from falling over; the pot-pushing frame pushes the tilted pots in the front row of the seedling storage tray onto the seedling conveyor belt. Both the anti-tipping frame and the pot-pushing frame are equipped with sprockets, on which the same actuating chain is mounted. One end of the actuating chain is connected to a hydraulic cylinder rod, and the other end is connected to a tension spring. The hydraulic cylinder rod and the tension spring interact to control the movement of the anti-tipping frame and the pot-pushing frame. The sequence of actions of the seedling conveying control and actuation mechanism is as follows: the pot clamp rotates on the pot clamp frame. When it passes the swing rod, it causes the swing rod to swing once. At the end of the swing, the swing rod swings back under the action of the spring force. Each swing causes the seedling conveyor belt pulley to rotate unidirectionally at a certain angle, moving the seedling conveyor belt and the pots on it forward by one pot position, completing one single seedling conveying cycle.When the swing arm swings, the pawl mounted on the same sprocket as the swing arm drives the ratchet to rotate one tooth (the number of ratchet teeth is equal to the number of seedlings in a row on the seedling storage tray). When the ratchet rotates one revolution (the single feed has completed the conveying of a single seedling on the conveyor belt), the rotary valve lever mounted on the ratchet pulls the hydraulic rotary valve to rotate. The oil cylinder controlled by the valve pushes the sprocket on the seedling storage tray to rotate 90°, so that the seedlings in the first row on the seedling storage tray tilt forward at an angle of 50° to 60° with the horizontal plane. Because one end of the actuating chain is connected to the hydraulic cylinder rod and the other end to the tension spring, when the hydraulic cylinder rod pushes the seedling tray sprocket forward to rotate, the actuating chain moves in the opposite direction to the hydraulic cylinder rod under the pull of the tension spring, pulling the anti-tipping frame to the corresponding position to support the tilted row of seedlings. When the next seedling clamp drives the swing arm and the rotary valve lever to move, the rotary valve rotates under the action of the spring force, the hydraulic cylinder rod returns and pulls the actuating chain, causing the seedling pusher to push the seedlings onto the seedling conveyor belt. Before the hydraulic cylinder rod completes its return movement, the anti-tipping frame and the seedling pusher complete their return movement, thus ending one round of seedling conveying.

[0015] 5. The fully automatic seedling transplanter described above, wherein the trenching system comprises a trenching box (5-2), trenching and soil-crushing blades, a trenching shovel, a trenching blade clutch mechanism, a hydraulic multi-way valve (1-5), and a hydraulic cylinder (5-1). Two rows of trenching and soil-crushing blades are mounted on the main shaft of the transmission box, and the trenching shovel is mounted on the trenching transmission box; both can move according to the row spacing requirements. Operating the multi-way valve to actuate the cylinder enables the trenching mechanism to rise and fall. The trenching blade clutch mechanism installed in the transmission box allows the trenching blades to stop rotating after rising and leaving the soil, and to start rotating after descending and contacting the soil. The trenching shovel removes excess soil from the trench.

[0016] 6. The above-mentioned fully automatic nutrient pot seedling transplanter, wherein the pot clamp frame and soil-covering system consists of a pot clamp frame (6-1), a transmission and tension sprocket system, a pot clamp operation clutch mechanism, two sets of bent plate chains, multiple sets of pot clamps (6-3), a hydraulic multi-way valve (1-5), a pot clamp frame hydraulic cylinder (6-2), a clamp opening frame, and a soil-covering shovel (6-4). Its specific structure is as follows: ① The entire system, together with the upright frame and chain-type seedling storage tray system, is installed on a movable frame. The movable frame can move laterally on the machine frame guide rail according to the transplanting row spacing requirements (row spacing is adjustable). ② Sprockets and chains are installed on both sides of the pot clamp frame. The upright frame shaft hole, the pot clamp frame rotation center, and the center holes of the two drive sprockets are concentric. Its central shaft is a splined shaft, and the splined holes of the drive sprockets are mounted on the splined shaft. Operating the hydraulic multi-way valve via the hydraulic cylinder allows the pot clamp frame and soil-covering system to rotate and rise around the central shaft. ③ The pot clamp consists of a pot clamp plate (6-7), a pot clamp front claw (6-11) with a sprocket and shaft, a pot clamp rear claw (6-10) with a sprocket and shaft, a pot clamp drive sprocket and shaft, a pot clamp drive arm (6-8), a pot clamp push claw (6-5), and a chain (6-9). The pot clamp plate is mounted on two curved chains on the pot clamp frame at both ends according to the transplanting spacing (the spacing is adjustable). The drive sprocket, shaft, and drive arm are installed in the upper hole of the pot clamp plate; the front claw, sprocket, and shaft, and the rear claw, sprocket, and shaft are installed in the two lower holes respectively; the pot clamp push claw is installed on the rear claw. A chain is mounted on three sprockets, causing the front and rear claws to rotate in opposite directions. The two ends of the chain are connected to the drive sprocket and a tension spring respectively. When the drive arm touches the opening frame, the drive sprocket pulls the chain to open the front and rear claws; when the drive arm leaves the opening frame, the spring pulls the chain to close the front and rear claws. ④ During operation, the pot clamp rotates on the pot clamp frame along with the chain. When entering the trench, it moves backward at the same speed as the machine's forward movement, ensuring the seedling remains stationary relative to the ground during transplanting, thus improving transplanting quality. ⑤ The pot clamp's motion clutch is located within the gearbox. A lever connects the pot clamp frame and the motion clutch. The upward and downward movement of the pot clamp frame engages and disengages the motion clutch. The system's operation is as follows: the pot clamp frame descends, engaging the motion clutch. The pot clamp rotates on the pot clamp frame along with the chain. When the pot clamp passes the swing arm, it causes the swing arm to swing. When the pot clamp passes the seedling conveyor belt, the pot clamp pusher on the rear claw of the pot clamp picks up a seedling transported by the conveyor belt, which slides into the pot clamp at an inclined angle. When the seedling moves to the trench with the chain, the soil-covering shovel continuously covers the seedling with soil. When the pot clamp encounters the opening clamp, it is opened and then leaves with the chain, completing the seedling transplant. When the bowl clamp rises, the bowl clamp movement clutch disengages, causing the chain and bowl clamp to stop operating.

[0017] 7. The working process of the fully automatic seedling transplanter described above: Normal working steps: ① Inspect the machine and align the seedlings in the seedling trays with the L-shaped plate, then push them into the chain seedling tray in rows or as a whole. The number of seedlings in each row should match the specifications in the instruction manual, and there should be no missing seedlings or missing rows. Then operate the forward / reverse control handle (1-6) and the transmission clutch control handle (1-4) to put the gearbox in neutral and the transmission clutch in disengaged position. ② Start the engine (2-1) and operate the throttle to reach the required speed. ③ Operate the hydraulic cylinder control handle (1-1) of the trenching mechanism and the hydraulic cylinder control handle (1-2) of the pot clamp to raise the trenching box (5-2) and the pot clamp (6-1) to their highest positions. ④ Operate the forward and reverse handles (1-6) to put the machine in forward gear, and operate the transmission clutch control handle (1-4) to move the machine forward. ⑤ Operate the trenching hydraulic cylinder control handle (1-1) to lower the trenching mechanism and begin trenching and soil breaking. ⑥ Operate the hydraulic cylinder control handle (1-2) of the pot clamp to lower the pot clamp and begin transplanting the seedlings. Other working steps: ⑦ Steering: Operate the steering control handle (1-3) to turn the machine left and right. However, when the machine needs to make a large turn, step ③ must be operated first. ⑧ Reverse: When the machine needs to reverse, firstly, operate the transmission clutch control handle (1-4) to disengage the transmission clutch and stop the machine; secondly, operate step ③; thirdly, operate the forward and reverse handle (1-6) to put the machine in reverse gear; fourthly, operate the transmission clutch control handle (1-4) to engage the transmission clutch and reverse the machine. ⑨ Moving without transplanting: When the transplanting work is finished and the machine needs to move forward, operate step ③. ⑩ Stopping the machine: First, operate the transmission clutch control handle (1-4) to disengage the transmission clutch and stop the machine; second, operate step ③; third, operate the forward / reverse control handle (1-6) to put the gearbox in neutral; fourth, turn off the engine (2-1). Fifth, operate the transmission clutch control handle (1-4) to engage the transmission clutch.
