Description

TECHNICAL FIELD

[0001] The present application belongs to the field of agricultural machinery, and particularly relates to an automatic reseeding garlic seeding machine and a seeding method thereof. BACKGROUND

[0002] Garlic seeding machines have been widely used in China, but the existing garlic seeding machines using spoon chain type seed pickers often have the problems of missing seeds (empty spoons) and over-seeding (one spoon with multiple seeds) due to the chain transmission polygon effect, the irregular shape of garlic seeds, or the size difference of garlic seeds, which causes the size of the seed picking spoon to be unable to fully adapt, resulting in land and seed waste, reducing the yield of garlic, and seriously affecting the economic income of garlic farmers. At present, the methods for dealing with missing seeds and over-seeding are mostly manual reseeding and removal, which is labor-intensive, low-efficiency, and increases the cost of garlic planting. With the rapid development of sensor technology, the detection method of missing seeds and automatic reseeding of the garlic seeding machine has gradually matured, but there is a lack of effective detection method for distinguishing single seeds and over-seeding and mechanical device for preventing over-seeding.

A seed supplementing device is arranged in the seed supplementing channel of each flow dividing mechanism, and the seed supplementing spoon of the seed supplementing device is higher than the seed supplementing channel when the seed supplementing spoon is in the notch position of the seed supplementing box.

[0012] Preferably, the two sides of the driven sprocket and the second driven sprocket are fixed with seed protection plates.

[0013] Preferably, the seed supplementing spoon is embedded in the stepped groove on the circumference of the seed supplementing wheel body.

[0014] The seed planting method of the automatic seed supplementing type garlic planter is as follows:

[0015] Firstly, the frame is hung on the tractor, and the tractor drives the frame to move forward, so that the ground wheel rotates. The ground wheel drives two intermediate sprockets and intermediate shafts to rotate through the ground wheel shaft chain wheel and transmission chain 1, and then drives the seed metering shaft to rotate through transmission chain 2 and the seed metering shaft input sprocket, so as to provide power for the spoon chain type seed taking mechanism. At the same time, the seed metering shaft drives the reseeding shaft to rotate through the seed metering shaft output sprocket, transmission chain 3 and the reseeding shaft input sprocket, so as to provide power for the reseeding mechanism. The seed metering shaft drives the corresponding seed taking chain to rotate through the corresponding driving sprocket, and then drives the corresponding driven shaft 1, driven shaft 2 and transmission shaft 3 to start rotating through the corresponding driven sprocket 1, driven sprocket 2 and driven sprocket 3 respectively. The seed taking spoons rotate with the corresponding seed taking chains. When a part of the seed taking spoons are driven by the corresponding seed taking chains to move upward along the vertical direction, a row of seed taking spoons enter the corresponding seed storage space 1 along the corresponding anti-leakage groove, and agitate the garlic seeds inside. Under the action of the gravity of the garlic seeds and the collision and friction between the garlic seeds, a row of seed taking spoons are filled with seeds. Then, a row of seed taking spoons enter the corresponding seed storage space 2 along the corresponding anti-leakage groove for secondary filling. After the second filling, most of the seed taking spoons with missing seeds obtain garlic seeds, and the garlic seeds on the upper part of most of the seed taking spoons with double seeds fall off under the impact of the garlic seeds in the corresponding seed storage space 2, leaving only one garlic seed. Then, the seed taking chains continue to drive the corresponding seed taking spoons to move. When the seed taking spoons pass through the driven sprocket 3, if the seed taking spoons carry garlic seeds, the garlic seeds fall into the back of the corresponding previous seed taking spoon under the action of the centrifugal force and the gravity of the garlic seeds, and slide along the seed guide groove. The seed taking spoons are transported to the seed dropping point. If the seed taking spoons carry garlic seeds, the garlic seeds fall into the corresponding detection mechanism under the action of gravity after losing the support of the corresponding seed guide groove. The single-chip microcomputer obtains the seed taking state of the corresponding seed taking spoon according to the capacitance value detected by each detection mechanism. When the detection result of the seed taking state of a certain seed taking spoon is double seeds, the single-chip microcomputer controls the rudder of the corresponding shunt mechanism to rotate the corresponding shunt plate to block the seed falling channel. The garlic seeds falling from the detection mechanism fall into the corresponding garlic seed collection box through the shunt plate, and then the shunt plate rotates to reset. When the detection result of the seed taking state of a certain seed taking spoon is missing seeds or single garlic seed, the corresponding shunt mechanism does not act. If there is a single garlic seed, the single garlic seed falls into the soil through the seed falling channel of the corresponding seed guide pipe. If the detection result of the seed taking state of the seed taking spoon is missing seeds or double seeds, the single-chip microcomputer controls the corresponding reseeding device in the reseeding mechanism to reseed and plant.

[0016] Preferably, each reseeding device in the reseeding mechanism performs reseeding work after preparation. The preparation process is as follows:

[0017] The single-chip microcomputer controls energization of electromagnetic clutches of each seed supplementing device, and the driving rotors and driven rotors of each electromagnetic clutch are attracted under the action of a magnetic field, the seed supplementing shaft in the seed supplementing mechanism drives the seed supplementing wheels fixed with the driven rotors through the driving rotors to rotate, and a seed supplementing spoon fixed on each seed supplementing wheel passes through the gap and brush on the corresponding seed supplementing box to enter the seed taking stage to take seeds; after the seed supplementing spoons for taking seeds run through the seed conveying stage to the waiting seed supplementing position at the highest part of the seed supplementing wheels, and wait to enter the seed supplementing stage, the single-chip microcomputer controls de-energization of the electromagnetic clutches, the driving rotors are separated from the corresponding driven rotors, and the seed supplementing wheels stop rotating; meanwhile, the next seed supplementing spoon on each seed supplementing wheel completes seed taking, waits to run to the waiting seed supplementing position, the previous seed supplementing spoon waits to enter the transition stage, and the remaining seed supplementing spoon waits to enter the seed taking stage.

[0018] Preferably, the seed supplementing planting working process of the seed supplementing mechanism is as follows:

[0019] When the detection mechanism judges that the seed taking state of a seed taking spoon is missing or over-supplementing, the single-chip microcomputer controls energization of the electromagnetic clutch of the corresponding seed supplementing device, the driving rotor of the corresponding electromagnetic clutch is attracted to the corresponding driven rotor under the action of a magnetic field, the seed supplementing shaft in the seed supplementing mechanism drives the seed supplementing wheels fixed with the corresponding driven rotors through the corresponding driving rotor to rotate 90° to supplement seeds, and the corresponding garlic seeds are supplemented into the seed supplementing channel in the corresponding shunt mechanism under the action of centrifugal force and gravity, and then fall into the soil through the seed falling channel of the corresponding seed guide pipe; then the single-chip microcomputer controls de-energization of the corresponding electromagnetic clutch, the corresponding driving rotor is separated from the corresponding driven rotor, and the corresponding seed supplementing wheel stops rotating. Meanwhile, the corresponding next seed supplementing spoon with the garlic seeds is at the waiting seed supplementing position, and waits to receive the next seed supplementing instruction.

[0020] The present application has the following beneficial effects:

[0021] 1. The garlic seed planting machine provided by the present application takes seeds from the seed box through the spoon chain type seed taking mechanism, and sets a detection mechanism and a shunting mechanism to process the double seeds, and after the double seed processing, the shunting mechanism is planted by the reseeding mechanism, and when the detection mechanism detects the missing seeds, the shunting mechanism is also planted by the reseeding mechanism, so that the single garlic seed planting rate is greatly improved. The detection mechanism adopts a capacitive sensor, which detects the seed filling state of the seed taking spoon of the spoon chain type seed taking mechanism by using the dielectric property of garlic. The single garlic seed and the double garlic seed are obviously different, and the garlic seeds taken by the two different state seed taking spoons are different in the capacitance change amount measured by the capacitive sensor, so that the seed taking state of the seed taking spoon can be distinguished as single or double. Compared with the commonly used photoelectric sensor, the detection accuracy is affected by factors such as field dust and sunlight, and it is difficult to distinguish the seed taking state of the seed taking spoon as single or double. The capacitive sensor can effectively solve the problem of difficult detection of double seeds. When the detection result of the capacitive sensor is double seeds, the corresponding shunting device is driven by the single-chip microcomputer to drive the corresponding rudder to rotate the corresponding shunting plate, and the corresponding seed falling channel is shielded. At the same time, the garlic seeds fall into the garlic seed storage box from the double seed recovery channel through the shunting plate, and the shunted garlic seeds are collected for subsequent garlic planting operation, reducing the waste of garlic seeds.

[0022] 2. The present application is provided with a main seed box and an additional seed box, which adopts a double-layer seed box structure, and the seed taking spoon is filled twice, effectively increasing the efficient filling area, improving the filling success rate, and greatly reducing the missing rate and double seed rate of the spoon chain type seed taking mechanism, improving the performance of the spoon chain type seed taking mechanism, and reducing the pressure on the shunting mechanism and the reseeding mechanism.

[0023] 3. The reseeding device of the present application adopts a spoon wheel type structure, which is compact in structure, and the power of the reseeding mechanism is provided by the friction between the ground wheel and the ground, without the need to install other power sources, saving cost. At the same time, the single-chip microcomputer controls the movement of each reseeding wheel through the electromagnetic clutch, realizes independent reseeding, and each reseeding device does not affect each other.

[0050] First, the rack is hung on the tractor, the tractor drives the rack forward, the ground wheel 11 rotates, the ground wheel 11 drives the two intermediate sprocket 13 and intermediate shaft through the ground wheel shaft chain wheel 12 and transmission chain one, then through the transmission chain two and seedling spacing shaft input sprocket 14 to drive the seedling spacing shaft 411 to rotate, provide power for the spoon chain type seed taking mechanism 4, at the same time, the seedling spacing shaft 411 drives the complementary seedling spacing shaft 71 to rotate through the seedling spacing shaft output sprocket 15, transmission chain three and complementary seedling spacing shaft input sprocket 16, provides power for the complementary seedling spacing device. The seedling spacing shaft 411 drives the corresponding seed taking chain 44 to rotate through each driving sprocket 410, and then drives the corresponding driven shaft one, driven shaft two and transmission shaft three to start rotating through the corresponding driven sprocket one 43, driven sprocket two 45 and driven sprocket three 47 respectively. Each seed taking spoon 41 rotates with the corresponding seed taking chain 44, when each seed taking chain 44 drives a part of the seed taking spoon 41 to start moving upward along the vertical direction, a row of seed taking spoons 41 enter the corresponding seed storage space one along the corresponding anti-leakage groove 33, and agitate the garlic seeds inside, the flowability of the garlic seeds in each seed storage space one increases, under the action of the gravity of the garlic seeds and the collision and friction between the garlic seeds, a row of seed taking spoons 41 are filled with seeds, then a row of seed taking spoons 41 enter the corresponding seed storage space two along the corresponding anti-leakage groove 33 to be filled with seeds again; after the second filling, most of the seed taking spoons 41 that leak seeds get garlic seeds, most of the seed taking spoons 41 that are overfilled drop under the impact of the garlic seeds in the corresponding seed storage space two, leaving only one garlic seed. Then each seed taking chain 44 continues to drive the corresponding seed taking spoon 41 to move, when the seed taking spoon 41 passes through the driven sprocket three 47, if the seed taking spoon 41 carries garlic seeds, the garlic seeds fall into the back of the corresponding previous seed taking spoon 41 under the action of the centrifugal force and the gravity of the garlic seeds, and slide along the seed guide groove 48, and the seed taking spoon 41 is moved to the seed dropping point, if the seed taking spoon 41 carries garlic seeds, the garlic seeds lose the support of the corresponding seed guide groove 48 and fall into the corresponding detection mechanism 5 under the action of gravity, the single-chip microcomputer obtains the seed taking state of the corresponding seed taking spoon 41 according to the capacitance value detected by each detection mechanism 5 (the detection signal of the capacitor plate 53 is transmitted to the single-chip microcomputer through the signal processing chip 54), and provides a basis for each shunt mechanism 6 and the complementary seedling spacing device; when the seed taking state detection result of a certain seed taking spoon 41 is overfilled, the rudder 64 in the corresponding shunt mechanism 6 drives the corresponding shunt plate 62 to rotate to block the seed falling channel (counterclockwise rotation 90°), as shown in Figure 8 , the garlic seeds falling from the detection mechanism 5 fall into the corresponding garlic seed collection box 63 along the shunt plate 62, and then the shunt plate 62 rotates to reset (clockwise rotation 90°); when the seed taking state detection result of a certain seed taking spoon 41 is leaky or single garlic seed, the corresponding shunt mechanism 6 does not act, if there is single garlic seed, the single garlic seed falls into the soil through the seed falling channel of the corresponding seed guide pipe 61, as shown in Figure 7As shown; wherein, if the seed taking state detection result of the seed taking scoop 41 is missing seed or over-seeding, the corresponding seed supplementing device in the seed supplementing mechanism 7 is controlled by the single-chip microcomputer to supplement and plant the seeds.

[0051] As a preferred embodiment, the capacitance values of the two capacitor plates 53 of the detection mechanism 5 when there is no garlic seed in the detection area, when there is a single garlic seed in the detection area, and when there are over-seeded garlic seeds are measured in advance, and the capacitance value of the two capacitor plates 53 when there is a single garlic seed in the detection area is set as the capacitance threshold value. When the capacitance value of the two capacitor plates 53 is lower than the capacitance threshold value, it is determined that the seed is missing, and when the capacitance value is higher than the capacitance threshold value, it is determined that the seed is over-seeded. According to the capacitance value of the two capacitor plates 53 of each detection mechanism 5, the position of the shunt plate 62 in the corresponding shunt mechanism 6 is controlled to control the opening and closing of the seed falling channel in the corresponding shunt mechanism 6, so that the over-seeding phenomenon is effectively solved, and the waste of garlic seeds is avoided.

[0052] As a preferred embodiment, each seed supplementing device in the seed supplementing mechanism 7 needs to be prepared before supplementing and planting seeds, and the preparation process is as follows:

[0053] The working process of the seed supplementing wheel 75 of the seed supplementing device has four stages: seed taking stage, seed transporting stage, seed planting stage, and transition stage, as shown. Figure 11 The single-chip microcomputer controls the electromagnetic clutch 74 of each seed supplementing device to be powered on, and the driving rotor 742 and the driven rotor 741 of each electromagnetic clutch 74 are attracted under the action of the magnetic field. The seed supplementing shaft 71 in the seed supplementing mechanism 7 drives the seed supplementing wheel 75 fixed with the driven rotor 741 to rotate through the driving rotor 742, and a seed supplementing scoop 72 fixed on each seed supplementing wheel 75 passes through the gap and the brush 76 on the corresponding seed supplementing box 73 to enter the seed taking stage to take seeds; after the seed supplementing scoops 72 that have taken seeds run through the seed transporting stage to the waiting seed supplementing position at the highest point of the seed supplementing wheel 75, they wait to enter the seed planting stage, and the single-chip microcomputer controls each electromagnetic clutch 74 to be powered off, and the driving rotor 742 and the corresponding driven rotor 741 are separated, and each seed supplementing wheel 75 stops rotating; at the same time, the next seed supplementing scoop 72 on each seed supplementing wheel 75 completes the seed taking through the same steps, waits to run to the waiting seed supplementing position, the previous seed supplementing scoop 72 waits to enter the transition stage, and the remaining seed supplementing scoop 72 waits to enter the seed taking stage.

[0054] As a preferred embodiment, the seed supplementing and planting working process of the seed supplementing mechanism 7 is as follows:

[0055] When the detection mechanism 5 judges that the seed taking state of a seed taking spoon 41 is missing or overloading, the single-chip microcomputer controls the electromagnetic clutch 74 of the corresponding seed supplementing device to be powered, the driving rotor 742 of the corresponding electromagnetic clutch 74 is attracted to the corresponding driven rotor 741 under the action of the magnetic field, the seed supplementing shaft 71 in the seed supplementing mechanism 7 drives the seed supplementing wheel 75 fixed with the corresponding driven rotor 741 to rotate 90° to perform seed dropping, the corresponding garlic seed is dropped into the seed supplementing channel in the corresponding shunt mechanism 6 under the action of the centrifugal force and its own gravity, as shown in Figure 12 Fig. 6, and falls into the soil through the seed dropping channel of the corresponding seed guide pipe 61; then the single-chip microcomputer controls the corresponding electromagnetic clutch 74 to be powered off, the corresponding driving rotor 742 is separated from the corresponding driven rotor 741, and the corresponding seed supplementing wheel 75 stops rotating. At the same time, the corresponding next seed supplementing spoon 72 carries the garlic seed to the waiting seed supplementing position and waits for the next seed supplementing instruction.
