Description

Technical Field

[0001] This invention relates to the field of agricultural equipment, and more particularly to a broad bean planting device and its planting method. Background Technology

[0002] Broad beans are an important economic crop. Currently, there are two main methods of broad bean cultivation: manual planting and mechanized planting. Manual planting is less efficient, requires more human resources, and is suitable for planting in small to medium-sized plots. Mechanized planting is more efficient, but small to medium-sized plots are often scattered, making it difficult for large machinery to access them. Furthermore, large machinery is not highly integrated, making operation and learning cumbersome. Moreover, most existing broad bean planting machines in China are hill-planting machines, which are large in size and cannot simultaneously perform the three processes of sowing, fertilizing, and mulching. They also cannot freely adjust the number of seeds sown or the furrow depth. These methods have drawbacks such as inability to cultivate small to medium-sized areas, low efficiency, inaccurate sowing, frequent missed sowing, easy seed jamming, and limited adaptability to various working conditions.

[0003] Therefore, it is necessary to design a broad bean planting device and its planting method to facilitate small-to-medium-scale planting and complete the five actions of broad bean planting process: trenching, sowing, covering with soil, water and fertilizer mixing and spraying, and covering with soil and film. It should also be able to flexibly adjust the trenching depth and sowing amount. Summary of the Invention

[0004] This solution addresses the problems and needs raised above by proposing a broad bean planting device and its planting method. Due to the adoption of the following technical features, it can achieve the above-mentioned technical objectives and bring about several other technical effects.

[0005] One object of the present invention is to provide a broad bean planting device, comprising:

[0006] Base;

[0007] The trenching mechanism, located at the front end of the base, includes a trenching drive motor and a trenching sprocket assembly connected thereto. The trenching sprocket assembly performs trenching action in the soil under the drive of the trenching drive motor.

[0008] A seeding mechanism, disposed near the furrowing mechanism, includes:

[0009] A seed bin has a receiving cavity, and a sowing notch is provided on the seed bin that communicates with the receiving cavity;

[0010] A seed tray is pivotally connected to the receiving cavity, and the seed tray has a sowing hole for accommodating broad bean seeds;

[0011] A first driving component, connected to the seed tray, is configured to drive the seed tray to rotate within the receiving cavity, such that when the seed tray rotates to the position of the seed notch, the projection of the seeding through hole on the bottom of the seed chamber overlaps with the seed notch;

[0012] A water and fertilizer mixing mechanism includes a water bucket, a mixing component, and a spray nozzle assembly. The mixing component is configured to mix the water and fertilizer in the water bucket to make them uniform, and the spray nozzle assembly is configured to spray the uniform water and fertilizer in the water bucket into a ditch.

[0013] A soil covering and film covering mechanism, located at the rear end of the machine base, includes: a base plate and a soil covering assembly and a film covering assembly connected to the base plate. The soil covering assembly includes multiple soil covering wheels, which are configured to gradually gather and cover the soil on both sides of the trench as the machine base moves. The film covering assembly includes a clamping unit and a film reel connected thereto. A film roll is mounted on the film reel. The film covering assembly is configured to rotatably release the film roll around the film reel under the clamping of the clamping unit and cover the trench that has passed through the soil covering area.

[0014] In this technical solution, the working process of the broad bean planting device is as follows: First, the first drive motor of the ditching mechanism drives the connected ditching sprocket assembly to perform the ditching action; then, the second drive assembly drives the seed tray to rotate in the receiving cavity, so that the broad bean seeds in the receiving cavity fall into the sowing holes, and when the sowing holes overlap with the sowing gaps during the rotation of the seed tray, the broad bean seeds are sown in the ditch; then, the stirring assembly of the water and fertilizer mixing mechanism stirs the water and fertilizer in the water tank to make it uniform, and the spraying assembly sprays the uniform water and fertilizer in the water tank into the ditch; finally, the multiple covering wheels of the soil covering assembly gradually gather the soil on both sides of the opened ditch towards the ditch to cover it; and the film covering assembly covers the covered ditch by rotating the film roll. This broad bean planting device can easily realize small-to-medium-scale planting and complete the four actions of ditching, sowing, soil covering, water and fertilizer mixing and spraying, soil covering and film covering in the broad bean planting process, and it is convenient to plant and greatly improves planting efficiency.

[0015] In addition, the broad bean planting device according to the present invention may also have the following technical features:

[0016] In one example of the invention, the grooved sprocket assembly further includes:

[0017] A direction-adjusting motor is fixedly connected to the base and has an adjusting shaft. The adjusting shaft is fixedly connected to the trenching sprocket assembly and configured to drive the trenching sprocket assembly to rotate about the adjusting shaft to adjust the angle between the trenching sprocket assembly and the ground.

[0018] In one example of the present invention, the seeding mechanism further includes:

[0021] In one example of the present invention, the seeding through holes include a plurality of holes arranged in an array along the circumferential and radial directions of the seed disc, wherein, during the rotation of the seed disc, the vertical projection of the plurality of seeding through holes arranged in the radial direction at the bottom of the seed chamber can overlap with the seeding gap.

[0022] In one example of the present invention, the seed chamber further includes a baffle fixedly connected to the inner wall of the receiving cavity, and the baffle extends along the radial direction of the receiving cavity, wherein the position of the baffle does not overlap with the position of the sowing notch;

[0023] When the seed tray rotates, the baffle rotates relative to the seed tray and moves the broad bean seeds located in the seed chamber into the sowing hole.

[0024] In one example of the present invention, the soil covering and film covering mechanism further includes: a film cutting assembly.

[0025] It is disposed on the rear side of the coating assembly and includes:

[0030] A film cutting plate is connected to the base plate. The film cutting plate has a cutting surface that is opposite to the film cutting knife. The film passes through the film cutting plate and is laid on the film cutting surface. When the film needs to be cut, the film cutting knife stops on the film cutting surface and moves from one side of the film cutting plate to the other side.

[0031] In one example of the present invention, the plurality of covering wheels are arranged in pairs to form a covering wheel group. The two covering wheels in the covering wheel group are symmetrically arranged in the transverse direction, and the span of the two covering wheels in the covering wheel group located at the front end is greater than the span of the two covering wheels in the covering wheel group located at the rear end in the transverse direction.

[0129] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0131] According to a first aspect of the present invention, a broad bean planting device 100, such as Figure 1 and Figure 2 As shown, it includes:

[0132] The machine base 10 includes, for example, a chassis 11 and guide wheels 12 pivotally mounted on the chassis 11, with a guide wheel motor 13 connected to each guide wheel 12, which drives the guide wheel 12 to rotate. During the sowing operation, the guide wheel 12 is driven to rotate by the guide wheel motor 13 and travels along a designated route in the field.

[0133] The trenching mechanism 20 is located at the front end of the base 10 and includes a trenching drive motor 21 and a trenching sprocket assembly 22 connected thereto. The trenching sprocket assembly 22 performs trenching action in the soil under the drive of the trenching drive motor 21. For example, an installation groove 14 is provided at the front end of the chassis 11 and the trenching mechanism 20 is connected in the installation groove 14.

[0134] The seeding mechanism 30, disposed near the furrowing mechanism 20, includes:

[0135] The seed bin 31 has a receiving cavity 3111, and the seed bin 31 has a sowing notch 312 that communicates with the receiving cavity 3111. For example, the seed bin 31 includes a bin body 311 and a support leg 314 provided at the lower end of the bin body 311. The support leg 314 can support the bin body 311, and a seed drop opening 15 is provided on the chassis 11, which corresponds to the sowing notch 312 of the seed bin 31. When the sowing mechanism 30 sows broad bean seeds, they can fall into the groove from the seed drop opening 15.

[0136] The seed tray 32 is pivotally connected to the receiving cavity 3111. The seed tray 32 has a sowing hole 321 for holding broad bean seeds. That is, the seed tray 32 rotates in the receiving cavity 3111 and drives the broad bean seeds loaded in the receiving cavity 3111 to rotate synchronously with the seed tray 32.

[0137] The first driving component 33 is connected to the seed tray 32 and is configured to drive the seed tray 32 to rotate within the receiving cavity 3111, such that when the seed tray 32 rotates to the position of the seed notch 312, the projection of the seeding through hole 321 on the bottom of the seed bin 31 overlaps with the seed notch 312.

[0138] The water and fertilizer mixing mechanism 40 includes a water tank 41, a mixing component 42, and a spray nozzle assembly 43. The mixing component 42 is configured to mix the water and fertilizer in the water tank 41 to make them uniform, and the spray nozzle assembly 43 is configured to spray the uniform water and fertilizer in the water tank 41 into the trench.

[0139] For example, the nozzle assembly 43 includes a nozzle 431 and a hose (not shown) connected thereto, as well as a pump (not shown). The nozzle 431 is mounted on the base plate 51 described below. The hose is connected to the water tank 41. The pump is connected to the water tank 41 and is connected to the nozzle 431 via the hose. The pump is used to pump water and fertilizer from the water tank 41, and the nozzle 431 is used to spray the water and fertilizer into the ditch.

[0140] The soil covering and film covering mechanism 50 is located at the rear end of the base 10 and includes: a base plate 51 and a soil covering assembly 52 and a film covering assembly 53 connected to the base plate 51. The soil covering assembly 52 includes a plurality of soil covering wheels 521, which are configured to gradually gather and cover the soil on both sides of the trench as the base 10 moves. The film covering assembly 53 includes a clamping unit 531 and a film roll 532 connected thereto. A film roll is mounted on the film roll 532. The film covering assembly 53 is configured to release the film rotatably around the film roll 532 under the clamping of the clamping unit 531 and cover the trench that has passed through the soil covering.

[0141] The working process of the broad bean planting device 100 is as follows: First, the first drive motor of the ditching mechanism 20 drives the ditching sprocket assembly 22 connected to it to perform the ditching action; then, the second drive assembly 35 drives the seed tray 32 to rotate in the receiving cavity 3111, so that the broad bean seeds in the receiving cavity 3111 fall into the sowing hole 321 and are sown in the ditch when the sowing hole 321 overlaps with the sowing notch 312 during the rotation of the seed tray 32; then, the stirring assembly 42 of the water and fertilizer stirring mechanism 40 stirs the water and fertilizer in the water tank 41 to make it uniform, and the spraying assembly 43 sprays the uniform water and fertilizer in the water tank 41 into the ditch; finally, the multiple covering wheels 521 of the covering assembly 52 gradually gather the covering soil on both sides of the opened ditch towards the ditch to cover it; and the film covering assembly 53 rotates the film roll 532 to cover the covered ditch. The broad bean planting device 100 can easily realize small-to-medium-scale planting and complete the four actions of broad bean planting process: trenching, sowing, soil covering, water and fertilizer mixing and spraying, and soil covering and film covering. Moreover, the planting is convenient and greatly improves planting efficiency.

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

[0143] Two parallel side panels 221;

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

[0145] A grooved chain 223 is wrapped around at least two sprockets 222 and is capable of rotating as at least one of the at least two sprockets 222 rotates;

[0146] Specifically, the two parallel side plates 221 are connected by at least two sprockets 222, each sprocket 222 having an axle that connects the two side plates 221 together. To improve the reliability of the overall structure, a fixed connecting shaft can be inserted 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 in turn driving the grooved chain 223 covering the at least two sprockets 222 to rotate, thereby realizing the creation of grooves on the ground. The grooved chain 223 has protrusions, and the grooved sprocket assembly 22 can flexibly create grooves on the ground, greatly saving manpower.

[0147] In one example of the present invention, such as Figure 3 As shown, the grooved sprocket assembly 22 further includes:

[0148] A direction adjustment motor 23 is fixedly connected to the 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] In other words, the direction adjustment motor 23 is fixed on the 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 trenches.

[0150] In one example of the present invention, such as Figure 4 and Figure 5 As shown, the seeding mechanism 30 further includes:

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

[0152] The second drive assembly 35 is connected to the shielding disk 34 and is configured to drive the shielding disk 34 to switch between a closed position where at least one of the seeding through holes 321 is closed and an open position where all the seeding through holes 321 are open, so as to adjust the seeding amount of the seeding notch 312.

[0153] For example, the shielding plate 34 is a semi-circular 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 semi-circular structure with an overall curvature greater than 180 degrees.

[0154] When it is necessary to increase the seeding amount of the seeding notch 312, the second drive component 35 drives the shielding disk 34 to rotate, thereby moving the shielding disk 34 away from the seeding notch 312 and reducing the area covering the seeding notch 312, so as to increase the seeding amount of the seeding through hole 321; when it is necessary to reduce the seeding amount of the seeding notch 312, the second drive component 35 drives the shielding disk 34 to rotate, thereby rotating the shielding disk 34 to the seeding notch 312 and increasing the area covering the seeding notch 312, so as to increase the seeding amount of the seeding through hole 321.

[0155] In short, the shading disk 34 can adjust the shading area of ​​the sowing gap 312 by driving the shading disk 34 through the second drive component 35, thereby flexibly adjusting the sowing amount of broad bean seeds.

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

[0157] Servo motor 351 has a drive shaft; it is fixedly connected to the bottom of seed chamber 31.

[0158] The first link 352 has one end hinged to the drive shaft;

[0159] The second link 353 has one end hinged to the other end of the first link 352 and the other end hinged to the shielding plate 34; wherein the hinge position between the second link 353 and the shielding plate 34 is located at the eccentric position of the shielding plate 34.

[0160] The servo motor 351 drives the drive shaft to rotate, thereby driving one end of the first link 352 to rotate around the drive shaft. The other end of the first link 352 is hinged to the second link 353, so the first link 352 drives the second link 353 to rotate. Then, the other end of the second link 353 drives the shielding plate 34 to rotate around its center position from the bias position. Finally, the shielding plate 313 rotates periodically around its own center position.

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

[0162] In one example of the present invention, the depth of the seeding hole 321 on the seed plate 32 is at least substantially the same as the thickness of the broad bean seed;

[0163] The depth of the sowing hole 321 is designed to be similar to the thickness of the broad bean seed, so that the broad bean seed falls into the sowing hole 321 and is basically flush with the bottom surface of the seed tray 32. This can prevent the broad bean seed from protruding out of the sowing hole 321 and being swept out of the sowing hole 321 by the baffle 313 during its rotation relative to the seed tray 32, thus ensuring the effectiveness and reliability of sowing.

[0164] In one example of the present invention, such as Figure 4 As shown, the seeding through holes 321 include a plurality of holes, which are arranged in an array along the circumferential and radial directions of the seed tray 32. During the rotation of the seed tray 32, the vertical projection of the plurality of seeding through holes 321 arranged in the radial direction at the bottom of the seed chamber 31 can overlap with the seeding notch 312.

[0165] For example, the seed tray 32 has a circular structure with two sowing holes 321 in the radial direction of its radius and four sets 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 in the radial direction at the bottom of the seed chamber 31 can overlap with the sowing notch 312, so that the maximum sowing amount can be two broad bean seeds. When it is necessary to control the sowing amount, one of the sowing holes 321 can be covered by rotating the baffle plate 313, so that one broad bean seed can be sown at a time.

[0166] In one example of the present invention, such as Figure 1 As shown, the seed bin 31 also includes a baffle 313, which is fixedly connected to the inner wall of the receiving cavity 3111 and extends along the radial direction of the receiving cavity 3111. The position of the baffle 313 does not overlap with the position of the sowing notch 312.

[0167] When the seed tray 32 rotates, the baffle 313 rotates relative to the seed tray 32 and moves the broad bean seeds located in the seed chamber 31 into the sowing hole 321;

[0168] In other words, the baffle 313 itself is stationary, while the seed tray 32 is rotating. 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 hole 321. That is, the broad bean seeds first slide along the bottom of the seed tray 32 and fall into the sowing hole 321 under the movement of the baffle 313. The sowing hole 321 filled with broad bean seeds moves to the sowing gap 312 of the seed bin 31 after passing the baffle 313, and falls into the groove from the sowing gap 312.

[0169] By setting up the baffle 313, the broad bean seeds can be moved into the sowing holes 321, so that each sowing 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 broad bean seeds from getting stuck between the seed tray 32 and the baffle 313 or between the sowing hole 321 and the baffle 313, thereby preventing the first driving component 33 from getting stuck. For example, the baffle 313 can be a rubber part.

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

[0172] Seed tray drive motor 331;

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

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

[0175] Since the first drive assembly 33 drives the shielding disk 34, and the shielding disk 34 is located in the receiving cavity 3111, the first drive assembly 33 needs to pass through the bottom of the seed chamber 31 located 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 shielding disk 34 located at its lower end when driving the shielding disk 34 to rotate.

[0176] The seed tray drive motor 331 drives the input shaft 332 to rotate, which in turn drives the shielding disc 34 connected to it to rotate to realize the sowing action.

[0177] As a preferred option, such as Figure 1As shown, the first drive assembly 33 also includes a hemispherical stop 334, which is fixed at the center of the seed tray 32 and fixedly connected to the input shaft 332, so that the broad bean seeds located in the receiving cavity 3111 cannot be close together at the center of the seed tray 32, which is beneficial to the effective sowing of the sowing mechanism 30.

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

[0179] Bracket 421;

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

[0181] Sun gear 423 is fixedly connected to bracket 421;

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

[0183] The pinion 425 is connected to the connecting rod 424 via a bearing and meshes with the sun gear 423;

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

[0185] The water and fertilizer mixing mechanism 40 includes a drive motor, a sun gear 423, a connecting rod 424, a pinion 425, a coupling, a mixing rod 426, and a support 421. The support 421 is connected to the base 10 to support the water and fertilizer mixing mechanism 40. The sun gear 423 is fixedly connected to the lower end of the support 421, the mixing motor 422 is fixedly connected to the upper end of the support 421, the connecting rod 424 is fixedly connected to the drive motor, the connecting rod 424 is connected to the pinion 425 through a bearing, and the pinion 425 is connected to the mixing rod 426 through the coupling.

[0186] The sun gear 423 does not contact the output shaft of the drive motor, nor does it contact the connecting rod 424. The sun gear 423 meshes with the pinion 425, and the teeth of the sun gear 423 have a 20° bend.

[0187] The connecting rod 424 has a 20° angle, which allows the sun gear 423 to mesh correctly with the pinion 425 and ensures the centered mixing of the water and fertilizer mixing mechanism 40.

[0188] When the stirring assembly 42 is working, the stirring motor 422 drives the sun gear 423 to rotate, which in turn drives the pinion 425 meshing with it to rotate synchronously. Since the pinion 425 is fixedly connected to the connecting rod 424, the connecting rod 424 also rotates synchronously with the pinion 425, which in turn drives the stirring rod 426 to rotate synchronously, thus stirring the water and fertilizer in the water tank 41.

[0189] The sun gear 423 of the water and fertilizer mixing mechanism 40 adopts a non-standard structure with a 20° bend in its teeth to ensure meshing with the inclined pinion 425. The connecting rod 424 has the same bend angle as the sun gear 423, also with a 20° bend, which realizes the centering and mixing of water and fertilizer, and makes the water and fertilizer more evenly mixed.

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

[0191] It is located on the rear side of the coating assembly 53 and configured to cut the film passing through the coating groove;

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

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

[0194] Nut 542 is adapted to the lead screw 541, and nut 542 is fixedly connected to the film cutting blade 543; and

[0195] The film cutting motor 544 has its output shaft fixedly connected to the lead screw 541 and is configured to drive the lead screw 541 to rotate so that the film cutting blade 543 can reciprocate along the lateral direction X of the extension of the lead screw 541.

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

[0197] Understandably, since the nut 542 also rotates during the rotation of the lead screw 541, in order to prevent the rotation of the nut 542 from affecting the linear movement of the cutting blade 543, the distance between the nut 542 and the base plate 51 is very close, so that it acts as a limiting component to restrict the rotation of the nut 542, thus making the nut 542 only move in a straight line; or by setting two lead screws 541 respectively with corresponding nuts 542, and the two nuts 542 are fixedly connected, this can prevent the nut 542 from rotating in the circumferential direction.

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

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

[0200] A film cutting plate 55 is connected to the base plate 51. The film cutting plate 55 has a film cutting surface 551 that is opposite to the film cutting blade 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 blade 543 abuts against the film cutting surface 551 and moves from one side of the film cutting plate 55 to the other side.

[0201] To facilitate efficient film cutting by the film cutting blade 543, a film cutting plate 55 is provided so that its cutting surface 551 can be located at the lower end of the film cutting blade 543. When film cutting is required, the film cutting motor 544 drives the film cutting blade 543 to move along the lateral direction X, so that the film cutting blade 543 abuts against the cutting surface 551 and moves from one side of the film cutting plate 55 to the other side to complete the film cutting.

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

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

[0204] For example, there are four covering wheels 521, each covering wheel group includes two covering wheels 521, and the covering wheels 521 are arranged in a figure-eight shape. The span of the two covering wheels 521 in the front covering wheel group is smaller than the span of the two covering wheels 521 in the rear covering wheel group in the lateral direction X.

[0205] In other words, firstly, the covering wheel assembly located at the rear end gathers and covers the soil on both sides of the trench into the trench under the action of the figure-eight-shaped covering wheels 521. Then, the covering wheel assembly located at the front end further gathers and covers the trench that has passed through the covering soil under the action of the figure-eight-shaped covering wheels 521, thus completing the filling of the trench with covering soil. The covering wheel assembly with the above structure can gather the soil on both sides of the trench into the trench, which is convenient and reliable.

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

[0207] The telescopic component 56 includes a cylinder 561 and a piston rod 562 telescopically connected to the cylinder 561. One of the cylinder 561 and the piston rod 562 is hinged to the base 10, and the other is hinged to the base plate 51. It is configured to allow the soil covering and film covering mechanism 50 to switch between a folded position and an unfolded position through telescopic movement.

[0208] For example, a vertical plate is fixedly connected to the rear end of the base 10, the cylinder 561 is hinged to the vertical plate, and the piston rod 562 is hinged to the base plate 51. When the soil covering and film covering mechanism 50 needs to be folded, the telescopic member 56 controls the telescopic rod to retract in the cylinder 561, and the soil covering and film covering mechanism 50 gradually rotates around the hinge point with the vertical rod as the center, 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 extend in the cylinder 561, and the soil covering and film covering mechanism 50 gradually rotates around the hinge point with the vertical rod as the center, so that the soil covering and film covering mechanism 50 contacts the ground. The folding of the soil covering and film covering mechanism 50 can be realized through the telescopic member 56, which facilitates the use and storage of the soil covering and film covering mechanism 50.

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

[0210] The pressing roller 57 is rotatably mounted on the rear end side of the base plate 51 and is configured to press onto the laid film to improve the flatness of the film, making the trench after covering with soil flatter, and improving the adhesion between the film and the trench after covering with soil, thereby improving the heat preservation effect of the film and helping the broad beans to grow in the later stage.

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

[0212] The movable guide rail 5311 is connected to the clamping motor 53131, and the movable guide rail 5311 is provided with a track 53111.

[0213] Two clamping blocks 5312 are movably disposed within the track 53111, and each clamping block 5312 has a half clamping cavity 53121 formed thereon. The two clamping blocks 5312 are symmetrically disposed and together define the complete clamping cavity A.

[0214] A clamping drive assembly 5313 is connected to 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 roll 532.

[0215] When the film roll 532 needs to be clamped, the clamping drive assembly 5313 drives the two clamping blocks 5312 to move towards each other along the track 53111, so that the two half-clamping cavities 53121 gradually approach and merge to form a complete clamping cavity A. As the clamping assembly continues to move, the film roll 532 is clamped tightly. When the film roll 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 move away from each other, releasing the film roll 532. This clamping unit 531 can flexibly clamp the film roll 532 and is easy to operate.

[0216] As a preferred option, such as Figure 9 and Figure 10 As shown, the clamping drive assembly 5313 includes:

[0217] Clamping motor 53131;

[0218] The first drive link 53132 is fixedly connected to the output shaft of the clamping motor 53131;

[0219] The second drive link 53133 has one end hinged to one of the clamping blocks 5312, and the other end hinged to one end of the first drive link 53132.

[0220] The third drive link 53134 has one end hinged to another clamping block 5312 and the other end hinged to the other end of the first drive link 53132.

[0221] The clamping motor 53131 drives the first driving link 53132 to rotate in both directions, thereby enabling the two clamping blocks 5312 to move towards or away from each other.

[0222] Specifically, when the film roll 532 needs to be clamped, the clamping motor 53131 rotates forward, driving the first drive link 53132 to rotate synchronously. This causes the second drive links 53133 and the third drive links 53134 on both sides of the first drive link 53132 to move forward. Consequently, the two clamping blocks 5312 connected to the second drive links 53133 and the third drive links 53134 move towards each other along the track 53111. This causes the two semi-clamping cavities 53121 to gradually approach and merge to form a complete clamping cavity A. As the clamping assembly continues to move... The film roll 532 is clamped tightly. When it is necessary to replace and release the film roll 532, the clamping motor 53131 rotates in the opposite direction, driving the first drive link 53132 to rotate synchronously with it. This causes 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. This causes 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. This causes the two half clamping cavities 53121 to gradually move away from each other, releasing the film roll 532.

[0223] In one example of the present invention, such as Figure 11 As shown, it also includes: controller 60,

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

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

[0226] It is coupled to the water and fertilizer mixing mechanism 40 and is configured to control the mixing of water and fertilizer in the water tank 41 and to spray it.

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

[0228] The working process of the broad bean planting device 100 is as follows: First, the controller 60 controls the first drive motor of the ditching mechanism 20 to drive the connected ditching sprocket assembly 22 to perform the ditching action; then, the controller 60 controls the second drive assembly 35 to drive the seed tray 32 to rotate in the receiving cavity 3111, so that the broad bean seeds in the receiving cavity 3111 fall into the sowing hole 321 and are sown. When the sowing hole 321 overlaps with the sowing notch 312 during the rotation of the seed tray 32, the broad bean seeds are sown. The seeds are sown in the furrows; then, the controller 60 controls the mixing component 42 of the water and fertilizer mixing mechanism 40 to mix the water and fertilizer in the water tank 41 to make it uniform, and the controller 60 controls the nozzle component 43 to spray the uniform water and fertilizer in the water tank 41 into the furrows; finally, the controller 60 controls the multiple covering wheels 521 of the covering component 52 to gradually gather the covering soil on both sides of the furrow towards the furrow; and the film covering component 53 covers the covered furrows by rotating the film roll 532. This broad bean planting device 100 can easily realize small and medium-sized planting and complete the four actions of furrowing, sowing, covering, water and fertilizer mixing and spraying, covering and film covering in the broad bean planting process. Moreover, planting is convenient and greatly improves planting efficiency.

[0229] A method for planting broad beans according to the second aspect of the present invention, using the broad bean planting apparatus 100 as described above, includes the following steps:

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

[0231] S20: The second driving component 35 drives the seed tray 32 to rotate in the receiving cavity 3111, so that the broad bean seeds in the receiving cavity 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 tray 32, the broad bean seeds are sown in the groove.

[0232] S30: The mixing component 42 of the water and fertilizer mixing mechanism 40 mixes the water and fertilizer in the water tank 41 to make it uniform, and the nozzle assembly 43 sprays the uniform water and fertilizer in the water tank 41 into the trench.

[0233] S40: The soil covering assembly 52 gradually gathers and covers the soil on both sides of the trench into the trench using multiple soil covering wheels 521; and the film covering assembly 53 covers the trench by rotating the film roll 532.

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

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

[0236] This broad bean planting method can easily realize small-to-medium-scale planting and complete the four actions of broad bean planting process: trenching, sowing, covering with soil, mixing and spraying water and fertilizer, and covering with soil and film. Moreover, it is convenient to plant and greatly improves planting efficiency. The ditching mechanism 20 of this planting method adjusts its angle by rotating the direction adjustment motor 23, thus flexibly adjusting the ditching depth. The servo motor 351 of the sowing mechanism 30 controls the movable semi-circular disc to cover or expose the sowing hole 321 via a linkage mechanism, switching between single-seed and double-seed sowing modes, thus flexibly adjusting the number of seeds in each hole. The sun wheel 423 of the water and fertilizer mixing mechanism 40 of this planting method adopts a non-standard structure with a 20° bend in its teeth to ensure meshing with the inclined pinion 425. The connecting rod 424 has the same 20° bend as the sun wheel 423, achieving centered mixing of water and fertilizer, resulting in better uniform mixing. The soil covering and mulching mechanism 50 of this planting method can be raised and lowered by extending and retracting the electric push rod, thus protecting the ground and the soil covering and mulching mechanism 50.

[0237] The foregoing has described in detail, with reference to preferred embodiments, an exemplary implementation of the broad bean planting device 100 and its planting method proposed in this invention. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention without exceeding the protection scope of this invention, which is determined by the appended claims.
