Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery technology, specifically relating to a fertilization device for a tobacco seedling double-row transplanting device in a tobacco-grain intercropping system. Background Technology

[0002] With the intensifying greenhouse effect, the "high-temperature stress" caused by global warming poses a new and serious threat to global food security. The scarcity of land resources in tobacco-growing areas has led to an increasingly serious problem of continuous cropping of flue-cured tobacco. To address the obstacles of continuous cropping and low overall efficiency in flue-cured tobacco cultivation, upgrading and transforming existing large-scale tobacco planting methods is crucial. Research on a strip-planting model that integrates major grain crops with tobacco and combines agricultural machinery and agronomy is of great significance for achieving coordinated development of tobacco and grain, and for reducing labor and increasing income for tobacco farmers.

[0003] In the strip-planting intercropping model of tobacco with wheat, sweet potatoes, and peanuts, when tobacco seedlings are transplanted, the wheat growing in the field is in the heading and flowering stage, with a plant height of over 60 cm. Existing tobacco seedling transplanting machinery cannot cross rows while riding on the wheat. Therefore, there is an urgent need to develop a tobacco seedling transplanting device suitable for the strip-planting model of tobacco with wheat, and a fertilization device for the double-row transplanting of tobacco seedlings in the tobacco-grain intercropping model that applies fertilizer at the same time as transplanting the tobacco seedlings. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a fertilization device for a tobacco seedling double-row transplanting device used in tobacco-grain intercropping.

[0005] The technical solution of this utility model is implemented in the following manner:

[0006] A fertilization device for a double-row transplanting system for tobacco seedlings in a tobacco-grain intercropping system includes a fertilizer hopper mounted on a connecting rod, a fertilizer discharge pipe connected to the inside of a furrow opener, a battery mounted on a frame, and a limit switch mounted on a flat support plate near the end of the flexible turntable. The limit switch is in contact with the lower surface of the seedling support, and a fertilizer receiving pipe is connected to the fertilizer discharge pipe. A fertilizer discharger is mounted at the bottom of the fertilizer hopper, and the discharge pipe of the fertilizer discharger is connected to the fertilizer receiving pipe. The fertilizer hopper has a left bearing seat and a right bearing seat, and a fertilizer discharge shaft is rotatably connected to the left and right bearing seats. The fertilizer discharge shaft is connected to the fertilizer discharger via a transmission connection. A fertilizer discharge pulley is mounted on the fertilizer discharge shaft. A motor is mounted on the side of one end of the fertilizer hopper, and a motor pulley is mounted on the motor shaft. The motor pulley is connected to the fertilizer discharge pulley via a transmission belt. A time relay is mounted on the motor, and the time relay is electrically connected to the motor, the battery, and the limit switch.

[0007] Preferably, the fertilizer discharge device includes a first fertilizer discharge device, a second fertilizer discharge device, a third fertilizer discharge device, and a fourth fertilizer discharge device; the first fertilizer discharge device includes a first fertilizer shell connected to the bottom of the fertilizer hopper, a first fertilizer wheel rotating inside the first fertilizer shell, and a first fertilizer pipe communicating with the first fertilizer shell; the second fertilizer discharge device includes a second fertilizer shell connected to the bottom of the fertilizer hopper, a second fertilizer wheel rotating inside the second fertilizer shell, and a second fertilizer pipe communicating with the second fertilizer shell; the third fertilizer discharge device includes a third fertilizer shell connected to the bottom of the fertilizer hopper, a third fertilizer wheel rotating inside the third fertilizer shell, and a third fertilizer pipe communicating with the third fertilizer shell; the fourth fertilizer discharge device includes a fourth fertilizer shell connected to the bottom of the fertilizer hopper, a fourth fertilizer wheel rotating inside the fourth fertilizer shell, and a fourth fertilizer pipe communicating with the second fertilizer shell; the first fertilizer wheel, the second fertilizer wheel, the third fertilizer wheel, and the fourth fertilizer wheel are drively connected to the fertilizer discharge shaft.

[0008] Preferably, the furrow opener includes a left furrow opener and a right furrow opener. The inner side of the left furrow opener is connected to the lower left fertilizer pipe, which is connected to the first fertilizer inlet pipe and the second fertilizer inlet pipe. The first fertilizer inlet pipe is connected to the first row of fertilizer pipes, and the second fertilizer inlet pipe is connected to the second row of fertilizer pipes. The inner side of the right furrow opener is connected to the lower right fertilizer pipe, which is connected to the third fertilizer inlet pipe and the fourth fertilizer inlet pipe. The third fertilizer inlet pipe is connected to the third row of fertilizer pipes, and the fourth fertilizer inlet pipe is connected to the fourth row of fertilizer pipes.

[0009] This utility model has the following advantages:

[0010] The fertilization device of this tobacco-grain intercropping double-row transplanting system utilizes a mechanism where, as the seedling tray moves from the outside inward along the seedling delivery chain, the lower end of the tray contacts a limit switch. This limit switch sends a signal to a time relay, which controls the motor to rotate for 2-4 seconds. The motor pulley drives the fertilizer discharge pulley via a transmission belt. The fertilizer discharge pulley then drives the fertilizer discharge shaft, which in turn drives the first, second, third, and fourth fertilizer discharge wheels. Fertilizer flows through the first fertilizer discharge pipe into the first receiving pipe, the second into the second receiving pipe, and finally collects in the lower left fertilizer pipe, falling through the gap between the side of the left furrow opener and the supporting flexible rotating base plate to the bottom of the left furrow opener. Similarly, fertilizer flows through the third and fourth receiving pipes, converging in the lower right fertilizer pipe, and finally falls through the gap between the side of the right furrow opener and the supporting flexible rotating base plate to the bottom of the right furrow opener. This design allows for simultaneous fertilization during seedling transplanting, resulting in high efficiency and fertilizer savings. Attached Figure Description

[0032] Applying fertilizer at the same time as transplanting tobacco seedlings is efficient and saves fertilizer.

[0033] The method for transplanting tobacco seedlings using a double-row transplanting device for tobacco-grain intercropping includes the following steps:

[0034] Step 1: Hanging up the machine, placing the seedlings, and transplanting: Connect the suspension lug 5 of the tobacco seedling double-row transplanting device for intercropping tobacco and grain to the hydraulic lifting arm of the tractor, and connect the traction lug 2 to the tractor's traction plate; place the seedlings to be transplanted into the seedling tray 13; load the fertilizer into the fertilizer hopper 16; ride the tractor onto the wheat seedling ridge to pull the tobacco seedling double-row transplanting device for intercropping tobacco and grain, aligning its ground wheel 11.3, right furrow opener 8, left furrow opener 14, and soil pressing roller 9.3 with the reserved tobacco field in the wheat field;

[0035] Step 2, Moving Forward: The tractor drives the double-row transplanting device for tobacco seedlings in the tobacco-grain intercropping project forward. The ground wheel 11.3 moves forward clockwise while keeping close to the ground. The ground and the ground wheel 11.3 come into contact with each other, generating friction and a reaction force on the ground wheel teeth 11.3.1. The ground wheel 11.3 is used as the power source, driving the ground wheel axle 11.2 to rotate. The ground wheel axle 11.2 drives the ground wheel axle sprocket 11.4 to rotate. The ground wheel axle sprocket 11.4 drives the clamping shaft sprocket 6.2 and the worm gear shaft sprocket 7.12 to rotate through the transmission chain 12.

[0036] Step 3: Furrowing with furrow openers: Simultaneously, right furrow opener 8 and left furrow opener 14 are inserted into the ground surface to create furrows for burying seedlings.

[0037] Step 4: Clamping the soft turntable at an angle: Simultaneously, the clamping shaft sprocket 6.2 drives the clamping shaft 6.1 to rotate, and the clamping shaft 6.1 drives the clamping hard turntable 6.3 and the clamping soft turntable 6.4 to rotate. The combined action of the lower top roller 6.2.2 rolling along the clamping soft turntable base plate 6.3.1 and the upper pressure roller 6.5.5 rolling along the clamping soft turntable base plate sponge 6.3.2 causes the clamping soft turntable 6.4 to be folded at an angle parallel to the lower inclined support plate 6.5.3.

[0038] Step 5, Seedling Delivery: Simultaneously, the worm gear shaft sprocket 7.12 drives the worm gear shaft 7.11 to rotate, the worm gear shaft 7.11 drives the worm gear 7.14 to rotate, the worm gear 7.14 drives the worm 7.13 to rotate, the worm gear 7.13 drives the worm shaft 7.9 to rotate, the worm shaft 7.9 drives the drive sprocket 7.8 to rotate, the drive sprocket 7.8 drives the seedling delivery chain 7.6 to rotate around the driven sprocket 7.4, and the seedling delivery chain 7.6 drives the seedling tray 7.7 to move from the outside to the inside. The person sitting in seat 10 places the tobacco seedlings in the seedling tray 13 with the heads facing outwards into the moving seedling tray 7.7. When the seedling tray 7.7 moves to the inside, it flips over, and the tobacco seedlings in the seedling tray 7.7 just fall between the folded soft rotating plate 6.4 and the hard rotating plate 6.3. The roots of the tobacco seedlings protrude 30-50mm from the outer edge of the hard rotating plate 6.3.

[0039] Step Six, Fertilization: As the seedling conveyor chain 7.6 moves the seedling tray 7.7 from the outside to the inside, the lower end of the seedling tray 7.7 contacts the limit switch 26. The limit switch 26 sends a signal to the time relay 27, which controls the motor 21 to rotate for 2-4 seconds. The motor pulley 21.2 drives the fertilizer discharge pulley 22.1 to rotate via the transmission belt 23. The fertilizer discharge pulley 22.1 drives the fertilizer discharge shaft 22 to rotate, which in turn drives the first fertilizer discharge wheel 15.1, the second fertilizer discharge wheel 17.1, the third fertilizer discharge wheel 19.1, and the fourth fertilizer discharge wheel 20.1 to rotate. The fertilizer flows through the first row of fertilizer pipes 15.3 into the first fertilizer receiving pipe 14.2, and through the second row of fertilizer pipes 17.3 into the second fertilizer receiving pipe 14.3, converging into the lower left fertilizer pipe 14.1. The fertilizer then flows through the gap between the side of the left furrow opener 14 and the supporting soft rotating base plate 6.4.1, falling to the bottom of the left furrow opener 14. The fertilizer flows through the third row of fertilizer pipes 19.3 into the third fertilizer receiving pipe 8.2, and through the fourth row of fertilizer pipes 20.3 into the fourth fertilizer receiving pipe 8.3, converging into the lower right fertilizer pipe 8.1. The fertilizer then flows through the gap between the side of the right furrow opener 8 and the supporting soft rotating base plate 6.4.1, falling to the bottom of the right furrow opener 8.

[0040] Step 7, Clamping and Burying Seedlings: As the clamping hard turntable 6.3 and the clamping soft turntable 6.4 rotate within the furrow opener 8, the elasticity of the clamping soft turntable 6.4.1, which is bent into a folded position, makes the clamping soft turntable 6.4 parallel to the clamping hard turntable 6.3. When the clamping soft turntable sponge 6.4.2 and the clamping hard turntable sponge 6.3.2 clamp the bottom surface of the rotating head of the tobacco seedling, the tobacco seedling is placed upright above the fertilizer in the furrow opened by the furrow opener 8. At the same time, the soil turned over by the right furrow opener 8 and the left furrow opener 14 falls back to bury the fertilizer and the roots of the tobacco seedling, and the soil pressing rollers 9.3 on both sides of the furrow opener 8 compact the soil. The head of the tobacco seedling slides out from between the clamping soft turntable sponge 6.4.2 and the clamping hard turntable sponge 6.3.2.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
