[0140] The soil covering and film covering mechanism 50 is arranged on the rear end side of the machine base 10, and includes: a base plate 51 and a soil covering component 52 connected to the base plate 51, and a film covering component 53, wherein the soil covering component 52 includes a plurality of soil covering wheels 521, and the plurality of soil covering wheels 521 are configured to gradually gather and cover the soil on both sides of the opened groove toward the groove as the machine base 10 moves; the film covering component 53 includes a clamping unit 531 and a film reel 532 connected thereto, a film roll is installed on the film reel 532, and the film covering component 53 is configured to release the film by rotating around the film reel 532 under the clamping of the clamping unit 531 and cover the groove passing through the covered soil with film.

[0141] The working process of the broad bean planting device 100 is as follows: first, the first driving motor of the trenching mechanism 20 drives the trenching sprocket assembly 22 connected thereto to perform the trenching action; then, the second driving assembly 35 drives the seed disc 32 to rotate in the accommodating chamber 3111, so that the broad bean seeds in the accommodating chamber 3111 fall into the sowing through hole 321, and when the sowing through hole 321 overlaps with the sowing notch 312 during the rotation of the seed disc 32, the broad bean seeds are sown in the trench; then, the stirring assembly 42 of the water and fertilizer stirring mechanism 40 stirs the water and fertilizer in the water bucket 41 to make it uniform, and the nozzle assembly 43 sprays the uniform water and fertilizer in the water bucket 41 into the trench; finally, the multiple covering wheels 521 of the covering assembly 52 gradually gather the covering soil on both sides of the opened trench to cover the trench; and the film covering assembly 53 rotates the covered trench through the film reel 532 to cover the film. The broad bean planting device 100 can conveniently realize small and medium-scale planting and complete the four actions of furrowing, sowing, covering soil, mixing and spraying water and fertilizer, covering soil and covering film in the broad bean planting process, and is convenient for planting, greatly improving the planting efficiency.

[0142] In one example of the present invention, Figure 3 As shown, the trenching sprocket assembly 22 includes:

[0143] Two parallel side panels 221;

[0144] At least two sprockets 222 are arranged between the two side plates 221 and located on both sides of the side plates 221 in the length direction; wherein the first driving motor is connected to one of the sprockets 222;

[0145] a trenching chain 223, which is covered on at least two sprockets 222 and can rotate along with the rotation of at least one of the at least two sprockets 222;

[0146] Specifically, two parallel side plates 221 are connected by at least two sprockets 222, wherein each sprocket 222 is provided with an axle, and the two side plates 221 are connected together by the axle; in order to improve the reliability of the overall structure, a fixed connecting shaft can be passed between the two parallel side plates 221, and the first drive motor is fixedly connected to the axle of one of the sprockets 222, thereby driving the sprocket 222 to rotate and then driving the trenching chain 223 covered on at least two sprockets 222 to rotate, thereby realizing the opening of a trench on the ground; a protrusion is provided on the trenching chain 223, and the trenching sprocket assembly 22 can be used to flexibly open a trench on the ground, which greatly saves manpower.

[0147] In one example of the present invention, Figure 3 As shown, the trenching sprocket assembly 22 also includes:

[0148] A direction adjustment motor 23, which is fixedly connected to the machine base 10 and has an adjustment shaft, the adjustment shaft is fixedly connected to the trenching sprocket assembly 22, and is configured to drive the trenching sprocket assembly 22 to rotate around the adjustment shaft to adjust the angle between the trenching sprocket assembly 22 and the ground;

[0149] That is to say, the direction adjustment motor 23 is fixed to the machine base 10 through the motor connecting bracket, and its adjustment shaft is fixedly connected to the side plate 221, thereby driving the trenching chain 223 assembly to rotate around the adjustment shaft to adjust the angle between the entire trenching chain 223 wheel assembly and the ground, so that the trenching chain 223 wheel assembly can flexibly adjust the angle to open the trench.

[0150] In one example of the present invention, Figure 4 and Figure 5 As shown, the sowing mechanism 30 also includes:

[0151] A shielding plate 34 is pivotally disposed at the lower end of the accommodating cavity 3111;

[0152] A second driving assembly 35, which is connected to the shielding plate 34, is configured to drive the shielding plate 34 to switch between a closed position for closing at least one of the sowing through holes 321 and an open position for opening all of the sowing through holes 321, so as to adjust the sowing amount of the sowing gap 312;

[0153] For example, the shielding plate 34 is a half-disc structure, that is, a portion of the arc plate is cut off in the circumferential direction of the disk, so that the shielding plate 313 presents a half-disc structure with an overall arc greater than 180 degrees.

[0154] When the sowing amount of the sowing gap 312 needs to be increased, the second driving assembly 35 drives the shielding disc 34 to rotate, so as to move the shielding disc 34 away from the sowing gap 312, thereby reducing the area covering the sowing gap 312, so as to increase the sowing amount of the sowing through hole 321; when the sowing amount of the sowing gap 312 needs to be reduced, the second driving assembly 35 drives the shielding disc 34 to rotate, so as to rotate the shielding disc 34 to the sowing gap 312, thereby increasing the area covering the sowing gap 312, so as to increase the sowing amount of the sowing through hole 321;

[0155] In short, the shielding disk 34 can adjust the shielding area of ​​the sowing gap 312 through the driving shielding disk 34 of the second driving component 35, and then flexibly adjust the sowing amount of broad bean seeds.

[0156] In one example of the present invention, Figure 5 As shown, the second driving assembly 35 includes:

[0157] The steering gear 351 has a driving shaft and is fixedly connected to the bottom of the seed bin 31;

[0158] A first connecting rod 352, one end of which is hingedly connected to the driving shaft;

[0159] A second connecting rod 353, one end of which is hingedly connected to the other end of the first connecting rod 352, and the other end of which is hingedly connected to the shielding plate 34; wherein the hinge position of the second connecting rod 353 and the shielding plate 34 is located at an eccentric position of the shielding plate 34;

[0160] The servo 351 drives the driving shaft to rotate, thereby driving one end of the first connecting rod 352 to rotate around the driving shaft. The other end of the first connecting rod 352 is hinged to the second connecting rod 353, so that the first connecting rod 352 drives the second connecting rod 353 to rotate, and then the other end of the second connecting rod 353 drives the baffle plate 34 from the offset position to rotate around its center position, and finally realizes the periodic rotation of the baffle plate 313 around its own center position.

[0161] It should be noted that in order to facilitate the connection between the servo 351, the first connecting rod 352, and the second connecting rod 353 at the bottom of the seed bin 31, a hinge shaft 354 is used at the connection between the first connecting rod 352 and the second connecting rod 353, so that there is a certain connection distance between the first connecting rod 352 and the second connecting rod 353, which can leave a certain space for the connection of the servo 351.

[0162] In one example of the present invention, the depth of the sowing through hole 321 on the seed plate 32 is at least substantially consistent with the thickness of the broad bean seeds;

[0163] The depth of the sowing hole 321 is designed to be equivalent to the thickness of the broad bean seeds, so that the broad bean seeds can be basically flush with the bottom surface of the seed tray 32 after falling into the sowing hole 321. This can prevent the broad bean seeds from protruding from the sowing hole 321 and the broad bean seeds from being taken out of the sowing hole 321 after sweeping through the sowing hole 321 during the rotation of the baffle 313 relative to the seed tray 32, thereby ensuring the effectiveness and reliability of sowing.

[0164] In one example of the present invention, Figure 4 As shown, the sowing through holes 321 include a plurality of sowing through holes 321, and are arranged in an array along the circumferential direction and the radial direction of the seed disc 32, wherein during the rotation of the seed disc 32, the vertical projection of the plurality of sowing through holes 321 arranged along the radial direction at the bottom of the seed bin 31 can overlap with the sowing notch 312;

[0165] For example, the seed tray 32 is a circular structure, and two sowing holes 321 are opened in the radial direction of its radius distance, and four groups are arranged in an array in the circumferential direction. During the rotation of the seed tray 32, the vertical projection of the two sowing holes 321 arranged along the radial direction at the bottom of the seed bin 31 can overlap with the sowing gap 312, so that the maximum sowing amount of two broad bean seeds can be achieved. When the sowing amount needs to be controlled, one of the sowing holes 321 can be shielded by rotating the baffle plate 313 to achieve the sowing of one broad bean seed at a time.

[0166] In one example of the present invention, Figure 1 As shown, the seed bin 31 further includes a baffle 313, which is fixedly connected to the inner wall of the accommodating cavity 3111, and the baffle 313 is extended along the radial direction of the accommodating cavity 3111, wherein the position of the baffle 313 does not overlap with the position of the sowing notch 312;

[0167] When the seed disc 32 rotates, the baffle 313 rotates relative to the seed disc 32 and moves the broad bean seeds in the seed bin 31 to move into the sowing through holes 321;

[0168] That is to say, the baffle 313 itself does not move, while the seed tray 32 rotates, and the seed tray 32 and the baffle 313 move relative to each other. By setting the baffle 313, the broad bean seeds on the seed tray 32 can be moved into the sowing through hole 321, that is, the broad bean seeds first slide along the bottom of the seed tray 32 under the movement of the baffle 313 and fall into the sowing through hole 321, and the sowing through hole 321 filled with broad bean seeds moves to the sowing gap 312 of the seed bin 31 after passing through the baffle 313, and falls into the groove from the sowing gap 312;

[0169] By providing the baffle 313 , the broad bean seeds can be moved into the sowing through holes 321 , so that each sowing through hole 321 can be filled with broad bean seeds, thereby greatly improving the sowing accuracy of the broad bean planting device 100 .

[0170] In one example of the present invention, the baffle 313 is a flexible baffle. By designing the baffle 313 as a flexible baffle, it is possible to prevent the broad bean seeds from getting stuck between the seed tray 32 and the baffle 313 or the broad bean seeds from getting stuck between the sowing hole 321 and the baffle 313, thereby causing the first drive assembly 33 to get stuck; for example, the baffle 313 can be a rubber part.

[0171] In one example of the present invention, Figure 1 and Figure 5 As shown, the first driving assembly 33 includes:

[0172] Seed plate drive motor 331;

[0173] An input shaft 332, the input shaft 332 passes through the shielding plate 34 and is fixedly connected to the seed plate 32;

[0174] A bearing seat 333 connected between the shielding plate 34 and the input shaft 332, wherein the outer ring of the bearing seat 333 is fixedly connected to the shielding plate 34, and the inner ring of the bearing seat 333 is fixedly connected to the input shaft 332;

[0175] Since the first drive component 33 drives the baffle plate 34, and the baffle plate 34 is located in the accommodating chamber 3111, the first drive component 33 needs to pass through the bottom of the seed bin 31 at its lower end. In order to facilitate the connection of the input shaft 332, a bearing seat 333 needs to be set so that the input shaft 332 does not affect the baffle plate 34 at its lower end during the process of driving the baffle plate 34 to rotate.

[0176] The seed disk driving motor 331 drives the input shaft 332 to rotate, thereby driving the shielding disk 34 connected thereto to rotate to realize the seeding action.

[0177] As preferably, Figure 1As shown, the first drive assembly 33 also includes: a hemispherical stopper 334, which is fixed at the center position of the seed disk 32 and fixedly connected to the input shaft 332, so that the broad bean seeds located in the accommodating cavity 3111 cannot be close to the center position of the seed disk 32, which is beneficial to the effective sowing of the sowing mechanism 30.

[0178] In one example of the present invention, Figure 6 As shown, the stirring assembly 42 includes:

[0179] Bracket 421;

[0180] A stirring motor 422 is fixedly connected to the bracket 421;

[0181] The sun gear 423 is fixedly connected to the bracket 421;

[0182] A tie rod 424, fixedly connected to the output shaft of the stirring motor 422;

[0183] A pinion 425 connected to the tie rod 424 via a bearing and meshing with the sun gear 423;

[0184] A stirring rod 426, which is fixedly connected to the tie rod 424; for example, the pinion 425 is connected to the stirring rod 426 via the coupling;

[0185] The water-fertilizer stirring mechanism 40 includes a driving motor, a sun gear 423, a tie rod 424, a pinion 425, a coupling, a stirring rod 426, and a bracket 421. The bracket 421 is connected to the base 10 for supporting the water-fertilizer stirring mechanism 40. The sun gear 423 is fixedly connected to the lower end of the bracket 421, the stirring motor 422 is fixedly connected to the upper end of the bracket 421, the tie rod 424 is fixedly connected to the driving motor, the tie rod 424 is connected to the pinion 425 through a bearing, and the pinion 425 is connected to the stirring rod 426 through the coupling.

[0186] The sun gear 423 does not contact the output shaft of the driving motor, and the sun gear 423 does not contact the tie rod 424. The sun gear 423 is meshed with the pinion 425, and the gear teeth of the sun gear 423 are bent by 20 degrees.

[0187] The tie rod 424 has an angle of 20°, which can enable the sun gear 423 to mesh correctly with the pinion 425 and ensure the centered stirring of the water-fertilizer mixing mechanism 40.

[0188] When the stirring assembly 42 is working, the stirring motor 422 drives the sun gear 423 to rotate, thereby driving the pinion 425 meshing with it to rotate synchronously. Since the pinion 425 is fixedly connected to the tie rod 424, the tie rod 424 also rotates synchronously with the pinion 425, and finally drives the stirring rod 426 to rotate synchronously therewith, thereby stirring the water fertilizer in the water bucket 41.

[0189] The sun gear 423 of the water-fertilizer stirring mechanism 40 adopts a non-standard structure, and its teeth are bent at 20° to ensure engagement with the inclined pinion 425. The tie rod 424 has the same bending angle as the sun gear 423 and is also bent at 20°, thereby achieving centered stirring of the water and fertilizer and better mixing of the water and fertilizer.

[0190] In one example of the present invention, Figure 7 and Figure 8 As shown, the soil covering and film covering mechanism 50 further includes: a film cutting component 54,

[0191] It is arranged at the rear side of the film laminating assembly 53 and is configured to cut the film passing through the film laminating groove;

[0192] For example, the film cutting assembly 54 includes:

[0193] A lead screw 541 is pivotally connected to the base plate 51;

[0194] A nut 542 is matched with the lead screw 541 and is fixedly connected to the film cutting knife 543; and

[0195] The film cutting motor 544 has an output shaft fixedly connected to the lead screw 541 and is configured to drive the lead screw 541 to rotate so as to achieve reciprocating movement of the film cutting knife 543 along the lateral direction X along which the lead screw 541 extends;

[0196] That is to say, the film cutting motor 544 drives the lead screw 541 to rotate, and the rotation of the lead screw 541 will drive the rotation of the nut 542 threaded thereon. While rotating, the nut 542 moves linearly along the lateral direction X extended by the lead screw 541. Since the film cutting knife 543 is fixedly connected to the nut 542, the film cutting knife 543 also moves along the lateral direction X extended by the lead screw 541 with the nut 542. The reciprocating movement of the film cutting knife 543 in the lateral direction X is controlled by the forward and reverse rotation of the film cutting motor 544.

[0197] It is understandable that, as the screw 541 rotates, the nut 542 will also rotate. In order to prevent the nut 542 from rotating and affecting the linear movement of the film cutting knife 543, the nut 542 is very close to the base plate 51, so that it acts as a limiting member to limit the rotation of the nut 542, so that the nut 542 can only move along a straight line; or by setting two screws 541 and respectively passing through the corresponding nuts 542, and the two nuts 542 are fixedly connected, the nut 542 can be prevented from rotating in the circumferential direction.

[0198] It should be noted that the film cutting assembly 54 is not limited to the structure of the screw 541 and the nut 542, but may also have other structures. For example, the film cutting assembly 54 includes a telescopic rod and a film cutting motor 544, and the reciprocating linear motion of the film cutting motor 544 in the transverse direction X is achieved through the telescopic movement of the telescopic rod.

[0199] In one example of the present invention, Figure 7 and Figure 8 As shown, the film cutting assembly 54 also includes:

[0200] The film cutting plate 55 is connected to the bottom plate 51. The film cutting plate 55 has a film cutting surface 551 arranged opposite to the film cutting knife 543. The film passes through the film cutting plate 55 and is laid on the film cutting surface 551. When the film needs to be cut, the film cutting knife 543 stops on the film cutting surface 551 and moves from one side of the film cutting plate 55 to the other side thereof.

[0201] In order to facilitate the film cutting knife 543 to effectively cut the film, the film cutting plate 55 is arranged so that its film cutting surface 551 can be located at the lower end of the film cutting knife 543. When the film needs to be cut, the film cutting knife 543 is driven by the film cutting motor 544 to move along the transverse direction X, so that the film cutting knife 543 stops on the film cutting surface 551 and moves from one side of the film cutting plate 55 to the other side to complete the cutting of the film.

[0202] For example, the film cutting plate 55 is an L-shaped structure, and an oblong hole is opened and penetrated on the film cutting plate 55 . The film is released through the oblong hole via the film roll and laid on the film cutting surface 551 .

[0203] In an example of the present invention, a plurality of the covering wheels 521 are grouped in pairs to form a covering wheel group, and the two covering wheels 521 in the covering wheel group are symmetrically arranged in the transverse direction X, and the span of the two covering wheels 521 in the covering wheel group located on the front end side in the transverse direction X is greater than the span of the two covering wheels 521 in the covering wheel group located on the rear end side in the transverse direction X; wherein, the covering wheels 521 and the central axis of the base plate 51 in the longitudinal direction Y from the front end side to the rear end side form an acute angle; the longitudinal direction Y and the transverse direction X are perpendicular to each other.

[0204] For example, the soil covering wheels 521 include four, each of the soil covering wheel groups includes two soil covering wheels 521, and the soil covering wheels 521 are arranged in an eight-shaped shape, and the span of the two soil covering wheels 521 in the front wheel group in the transverse direction X is smaller than the span of the two soil covering wheels 521 in the rear wheel group in the transverse direction X;

[0205] That is to say, first, the covering wheel group located at the rear end side will gather and cover the covering soil on both sides of the groove into the groove under the action of the covering wheels 521 arranged in an eight-shape, and then the covering wheel group located at the front end side will further gather and cover the groove that has passed the covering soil into the groove under the action of the covering wheels 521 arranged in an eight-shape to complete the filling of the groove with soil; through the covering wheel group with the above structure, the covering soil on both sides of the groove can be gathered into the groove, which is convenient and reliable.

[0206] In one example of the present invention, Figure 7 and Figure 8 As shown, the soil and film covering mechanism 50 further includes:

[0207] The telescopic member 56 includes a cylinder body 561 and a piston rod 562 telescopically connected to the cylinder body 561, one of which is hinged to the machine base 10, and the other of which is hinged to the bottom plate 51, and is configured to switch the soil and film covering mechanism 50 between a folded position and an unfolded position through telescopic movement;

[0208] For example, a vertical plate is fixedly connected to the rear end side of the machine base 10, the cylinder body 561 is hingedly connected to the vertical plate, and the piston rod 562 is hingedly connected to the bottom plate 51; when the soil covering and film covering mechanism 50 needs to be folded, the telescopic member 56 controls the telescopic rod to perform a contraction movement in the cylinder body 561, and the soil covering and film covering mechanism 50 gradually rotates with the hinge with the vertical pole as the center of the circle so that the soil covering and film covering mechanism 50 leaves the ground; when the soil covering and film covering mechanism 50 needs to be unfolded, the telescopic member 56 controls the telescopic rod to perform an extension movement in the cylinder body 561, and the soil covering and film covering mechanism 50 gradually rotates with the hinge with the vertical pole as the center of the circle so that the soil covering and film covering mechanism 50 contacts the ground; the soil covering and film covering mechanism 50 can be folded by the telescopic member 56, which is convenient for the use and storage of the soil covering and film covering mechanism 50.

[0209] In one example of the present invention, Figure 7 and Figure 8 As shown, the soil and film covering mechanism 50 further includes:

[0210] The film pressing wheel 57 is rotatably disposed on the rear end side of the base plate 51 and is configured to be pressed on the laid film to improve the flatness of the film, make the grooves after covering with soil more flat, and better fit between the film and the grooves after covering with soil, thereby improving the thermal insulation effect of the film and facilitating the later growth of broad beans.

[0211] In one example of the present invention, Fig. 9 and Fig.10 As shown, the clamping unit 531 includes:

[0212] A movable guide rail 5311, a clamping motor 53131 is connected to the movable guide rail 5311, and a track 53111 is provided on the movable guide rail 5311;

[0213] Two clamping blocks 5312 are movably arranged in the track 53111, and a half clamping cavity 53121 is formed on each clamping block 5312. The two clamping blocks 5312 are symmetrically arranged to jointly define a complete clamping cavity A;

[0214] A clamping drive assembly 5313, wherein the clamping drive assembly 5313 is connected to the two clamping blocks 5312 and is configured to drive the two clamping blocks 5312 to move synchronously toward or away from each other to clamp or release the film reel 532;

[0215] When the film reel 532 needs to be clamped, the clamping drive assembly 5313 drives the two clamping blocks 5312 to move toward each other along the track 53111, so that the two half clamping cavities 53121 gradually come together to form a complete clamping cavity A, and the film reel 532 is clamped tightly as the clamping assembly continues to move; when the film reel 532 needs to be replaced and released, the clamping drive assembly 5313 drives the two clamping blocks 5312 to move away from each other along the track 53111, so that the two half clamping cavities 53121 gradually depart from each other to release the film axis of the film reel 532. The clamping unit 531 can flexibly clamp the film reel 532 and is easy to operate.

[0216] As preferably, Fig. 9 and Fig.10 As shown, the clamping drive assembly 5313 includes:

[0217] Clamping motor 53131;

[0218] A first driving connecting rod 53132, which is fixedly connected to the output shaft of the clamping motor 53131;

[0219] A second driving connecting rod 53133, one end of which is hinged to one of the clamping blocks 5312, and the other end of which is hinged to one end of the first driving connecting rod 53132;

[0220] A third driving link 53134, one end of which is hinged to the other clamping block 5312, and the other end of which is hinged to the other end of the first driving link 53132;

[0221] The clamping motor 53131 drives the first driving connecting rod 53132 to rotate forward and reversely, thereby realizing the toward or away movement of the two clamping blocks 5312 .

[0222] Specifically, when the film reel 532 needs to be clamped, the clamping motor 53131 rotates forward to drive the first drive link 53132 to rotate synchronously therewith, so that the second drive link 53133 and the third drive link 53134 on both sides of the first drive link 53132 move forward, and then the two clamping blocks 5312 connected to the second drive link 53133 and the third drive link 53134 move toward each other along the track 53111, so that the two half clamping cavities 53121 gradually move together to form a complete clamping cavity A. As the clamping assembly continues to move and when the film reel 532 needs to be replaced and released, the clamping motor 53131 rotates in the opposite direction to drive the first drive link 53132 to rotate synchronously therewith, thereby causing the second drive link 53133 and the third drive link 53134 on both sides of the first drive link 53132 to move in the opposite direction, and then causing the two clamping blocks 5312 connected to the second drive link 53133 and the third drive link 53134 to move away from each other along the track 53111, thereby causing the two half clamping cavities 53121 to gradually move away from the film axis of the film reel 532 and release it.

[0223] In one example of the present invention, Fig.11 As shown, it also includes: a controller 60,

[0224] It is coupled to the ditching mechanism 20 and is configured to control the ditching mechanism 20 to perform a ditching action;

[0225] It is coupled to the sowing mechanism 30 and is configured to control the sowing mechanism 30 to perform a sowing action;

[0226] It is coupled to the water-fertilizer stirring mechanism 40 and is configured to control the stirring of the water-fertilizer in the water bucket 41 and to spray it;

[0227] It is coupled to the soil covering and film covering mechanism 50 and is configured to control the soil covering component 52 to collect and cover the soil on both sides of the groove; and control the film covering component 53 to cover the covered groove through the film reel 532;

[0228] The working process of the broad bean planting device 100 is as follows: first, the controller 60 controls the first driving motor of the ditching mechanism 20 to drive the ditching sprocket assembly 22 connected thereto to perform a ditching action; then, the controller 60 controls the second driving assembly 35 to drive the seed disc 32 to rotate in the accommodating chamber 3111, so that the broad bean seeds in the accommodating chamber 3111 fall into the sowing through hole 321, and when the sowing through hole 321 overlaps with the sowing notch 312 during the rotation of the seed disc 32, the broad bean seeds are planted. The seeds are sown in the grooves; then the controller 60 controls the stirring assembly 42 of the water-fertilizer stirring mechanism 40 to stir the water and fertilizer in the water bucket 41 to make it uniform, and the controller 60 controls the nozzle assembly 43 to spray the uniform water and fertilizer in the water bucket 41 into the grooves; finally, the controller 60 controls the multiple covering wheels 521 of the covering assembly 52 to gradually gather the covering soil on both sides of the opened grooves to cover the grooves; and the film covering assembly 53 rotates the covered grooves through the film reel 532 to cover the film. The broad bean planting device 100 can conveniently realize small and medium-sized planting and complete the four actions of furrowing, sowing, covering, water-fertilizer mixing and spraying, covering and covering, and is convenient for planting, greatly improving the planting efficiency.

[0229] According to the second aspect of the present invention, a planting method of the broad bean planting device 100 as described above comprises the following steps:

[0230] S10: The first driving motor of the ditching mechanism 20 drives the ditching sprocket assembly 22 connected thereto to perform a ditching action;

[0232] S30: The stirring assembly 42 of the water-fertilizer stirring mechanism 40 stirs the water-fertilizer in the water bucket 41 to make it uniform, and the spray head assembly 43 sprays the uniform water-fertilizer in the water bucket 41 into the groove;

[0233] S40: The soil covering wheels 521 of the soil covering assembly 52 gradually gather the soil on both sides of the opened groove toward the groove to cover it; and the film covering assembly 53 rotates the covered groove through the film reel 532 to cover it with film.

[0234] Specifically, first, the controller 60 controls the first drive motor of the trenching mechanism 20 to drive the trenching sprocket assembly 22 connected thereto to perform the trenching action; then, the controller 60 controls the second drive assembly 35 to drive the seed disc 32 to rotate in the accommodating chamber 3111, so that the broad bean seeds in the accommodating chamber 3111 fall into the sowing through hole 321, and the broad bean seeds are sown in the trench when the sowing through hole 321 overlaps with the sowing notch 312 during the rotation of the seed disc 32; then, the controller 60 controls the stirring assembly 42 of the water-fertilizer stirring mechanism 40 to stir the water and fertilizer in the water bucket 41 to make it uniform, and the controller 60 controls the nozzle assembly 43 to spray the uniform water and fertilizer in the water bucket 41 into the trench; finally, the controller 60 controls the multiple covering wheels 521 of the covering assembly 52 to gradually gather the covering soil on both sides of the opened trench toward the trench to cover it; and the film covering assembly 53 rotates the covered trench through the film reel 532 to cover the film.

[0235] It should be noted that in order to conveniently and concisely describe the planting method, the working principles of other relevant structural components of the broad bean planting device 100 involved in the planting method can refer to the relevant parts of the above-mentioned broad bean planting device 100, and will not be repeated here.

[0236] The broad bean planting method can conveniently realize small and medium-scale planting and complete the four actions of furrowing, sowing, soil covering, water and fertilizer mixing and spraying, soil covering and film covering in the broad bean planting process, and the planting is convenient, which greatly improves the planting efficiency.
