Description

Technical Field

By improving varieties and developing a series of deep-processed products, various lotus root planting areas have not only met consumers' diverse "demands for eating lotus roots", but also driven lotus root farmers to obtain higher returns, making the lotus root industry an advantageous and characteristic leading industry for regional economic development. However, my country started late in the development of lotus root planting equipment, and the planting equipment is relatively backward. At present, it is still mainly planted manually. With the development of society, my country's demand for lotus roots is increasing, and the emergence of intelligent lotus root planting machines is urgent.

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 1 The orientation is used as a reference.

[0051] like Figures 1 to 4As shown, the present invention provides a multifunctional lotus root planting machine, which includes a frame 10, a seedling separation and anti-blocking device 20, a lotus seedling conveying device 30, a ditching device 40 and a soil covering device 50. A walking mechanism 11 is arranged on the frame 10. Among them, the walking mechanism 11 may include a motor, a transmission system and multiple pairs of walking wheels, etc. In conventional implementations, reference can be made to existing agricultural machinery equipment with walking functions to achieve the self-walking function of the overall equipment. However, in a preferred embodiment, the walking wheels can be selected from the wheels used in tractors to adapt to the planting environment of dry land and paddy fields. Alternatively, in other embodiments, the walking mechanism 11 includes multiple pairs of walking wheels, but there is no power system for driving the walking, and a hand-pushing handrail 12 is arranged on the frame 10, and the grower can use a hand-pushing method to achieve the movement of the frame 10.

[0052] See also Figure 5 and Figure 6 The seedling separation and anti-blocking device 20 includes a seedling loading bucket 21 and a vibration mechanism 22 both of which are arranged on the frame 10. A rectangular seedling lowering opening 211 is opened at the bottom of the seedling loading bucket 21. The vibration mechanism 22 can drive the lotus seedlings in the seedling loading bucket 21 to fall from the lower seedling opening 211 in sequence to avoid the blockage of the lotus seedlings, thereby facilitating subsequent operations. Figure 6 The multiple dotted circles in the figure indicate the positions of the lotus seedlings. The lotus seedling conveying device 30 is arranged on the frame 10 and is located below the seedling loading bucket 21. The lotus seedling conveying device 30 includes a chain transmission mechanism 31 and a plurality of sorting partitions 32 arranged in sequence along the conveying direction B of the chain transmission mechanism 31. The traveling direction A of the frame 10, the length direction of the sorting partitions 32 and the length direction of the lower seedling opening 211 are parallel to each other and perpendicular to the conveying direction B of the chain transmission mechanism 31. Figure 6 The lotus seedlings falling from the lower seedling opening 211 will enter the sorting partition 32 in sequence. The length direction of the lotus seedlings is parallel to the length direction of the sorting partition 32. The speeds of the vibration mechanism 22 and the chain transmission mechanism 31 can be adjusted respectively, so that one lotus seedling falls into one sorting partition 32. Then, under the transmission action of the chain transmission mechanism 31, the lotus seedlings will move with the chain and fall from the sorting partition 32 to the ground in sequence. Figure 6 The landing position 33 of one embodiment is marked. In actual use, the lateral position of the landing position 33 of the lotus seedling can be adjusted by moving the lateral position of the chain transmission mechanism 31 as a whole.

[0053] In addition, the trenching device 40 can be lifted and lowered on the frame 10; the soil covering device 50 can be lifted and lowered on the frame 10. Figure 2 and Figure 6, the trenching device 40, the lotus seedling conveying device 30 and the soil covering device 50 are arranged in sequence from front to back along the travel direction A of the frame 10. In the process of planting lotus seedlings in dry land, the frame 10 continuously moves along the travel direction A. During the movement, the trenching device 40 digs trenches on the land. As the frame 10 moves forward, the lotus seedlings that fall from the sorting partition 32 will enter the newly dug trenches in sequence, and the length direction of the lotus seedlings is consistent with the extension direction of the trench, and adjacent lotus seedlings are distributed at intervals in the trench. The grower can adjust the travel speed of the frame 10 to adjust the spacing between the lotus seedlings so that the planting of the lotus seedlings meets the planting requirements. Afterwards, the soil covering device 50 can fill the soil dug up beside the trench back into the trench, thereby completing the planting of the lotus seedlings.

[0054] Dryland planting realizes the integration of trenching, seedling delivery and soil covering, and the whole lotus seedling planting process is fast and efficient, thereby realizing large-scale mechanized lotus root planting. In addition, the trenching device 40 and the soil covering device 50 are both arranged in a liftable manner, and can be retracted to the top when idle or when paddy field planting is carried out, without taking up extra space, which is convenient for storage and also convenient for the transfer and transportation of the equipment when idle.

[0055] In a preferred embodiment, see again Figure 3 , Figure 5 and Figure 6 The bottom plate 212 of the seedling loading bucket 21 is tilted, and a lower seedling opening 211 is formed between the lower end of the bottom plate 212 and the side wall 213. The seedling loading bucket 21 also includes side baffles arranged on opposite sides of the bottom plate 212. The lower end of the bottom plate 212 is mounted on a support seat 214 located on the side baffles through a pair of bearings. The width of the lower seedling opening 211 is slightly larger than the maximum diameter of a lotus seedling, so that multiple lotus seedlings will not fall and are not easily blocked. The vibration mechanism 22 includes a vibration motor, a rotating shaft 221 connected to the output shaft of the vibration motor, and a cam 222 arranged on the rotating shaft 221 (see the side shape thereof). Figure 6 ). In order to improve stability, a pair of cams 222 are provided on the rotating shaft 221, and the two cams 222 are symmetrically arranged based on the cross section of the rotating shaft 221, and the upper end of the bottom plate 212 is overlapped on the cam 222. When the vibration motor drives the rotating shaft 221 to rotate, due to the characteristics of the cam 222, the bottom plate 212 will form a small amplitude shake, completing the seedling separation and anti-blocking during the falling process of the lotus seedlings. In addition, the seedling bucket 21 can store more lotus seedlings at one time, realize batch planting, improve work efficiency and lotus seedling survival rate, and save manpower and material resources.

[0056] See again Figure 6The sorting partition 32 includes a first side plate 321 and a second side plate 322. The first side plate 321 and the second side plate 322 together form a structure with a V-shaped cross section. The first side plate 321 is installed on the chain of the chain transmission mechanism 31. The open end of the sorting partition 32 (based on the definition of the V-shaped structure) faces the direction opposite to the conveying direction B of the chain transmission mechanism 31. The sorting partition 32 located in the upper half of the chain is in a seedling-grafting state. The first side plate 321 remains horizontal, and the free end of the second side plate 322 is tilted upward. At this time, the outer side surface of the second side plate 322 can guide the moving path of the lotus seedlings. Specific combination Figure 6 When the lotus seedlings falling from the lower seedling mouth 211 touch the outer side surface of the second side plate 322 on the right, the lotus seedlings will be guided to move toward the sorting partition 32 on the left. Moreover, the second side plate 322 can also separate two adjacent lotus seedlings and prevent the lotus seedlings from rolling freely on the chain transmission mechanism 31.

[0057] At the same time, the sorting partition 32 located in the lower half of the chain is in a seedling-dropping state, the first side plate 321 remains horizontal, and the free end of the second side plate 322 is tilted downward, so that the lotus seedlings in the sorting partition 32 can slide obliquely downward based on the inclined guiding effect of the inner surface of the second side plate 322. The lotus seedlings can fall from the lower seedling opening 211 into the sorting partition 32 in the seedling-receiving state. When the sorting partition 32 with the lotus seedlings follows the chain and moves to the lower half of the chain, the sorting partition 32 is in a seedling-dropping state, and the lotus seedlings can slide along the second side plate 322. It should be noted that, in specific combination Figure 6In the case of the left end of the middle chain transmission mechanism 31, if there is no second side plate 322, the lotus seedlings will randomly fall just after passing the left end sprocket, and the starting position of the fall is relatively high. The landing position after falling is likely to be randomly distributed in the lateral direction (the left and right direction perpendicular to the travel direction A). In other words, even if the overall lateral position of the lotus seedling conveying device 30 is adjusted, it is impossible to guarantee that all lotus seedlings will fall into the ditch. Considering the randomness, some lotus seedlings will always fall outside the ditch. Moreover, if there is no second side plate 322, in order to make the lotus seedlings fall on the center line of the frame 10 as much as possible when they fall to the ground (that is, in order to make the landing position 33 correspond to the position of the ditching device 40 and the soil covering device 50 as much as possible), the overall structure of the chain transmission mechanism 31 needs to be completely set on the right half of the frame 10. In addition, considering the lateral displacement distance of the parabolic trajectory of the lotus seedlings when they fall to the ground, the left end of the chain transmission mechanism 31 also needs to be spaced a certain distance from the center line of the frame 10, which will cause the center of gravity of the overall equipment to shift to the right, and it is easy to roll over. In a preferred embodiment, due to the presence of the second side plate 322, the lotus seedlings will not fall immediately when they reach the left end sprocket, but continue to move to the lower half of the chain. For example, when the first side plate 321 bypasses the sprocket and remains horizontal again, the lotus seedlings will slide down obliquely along the inner side of the second side plate 322. At this time, the tendency of the lotus seedlings to fall to the left along the inner side of the second side plate 322 will be partially offset by the inertia of the lower half of the chain moving to the right. Moreover, when the lotus seedlings are separated from the free end of the second side plate 322, they are already very close to the ground, and the lateral position deviation of the lotus seedlings when they fall to the ground can be minimized to ensure that the lotus seedlings fall into the ditch as much as possible, thereby improving the overall efficiency of the planting process. Moreover, when the chain transmission mechanism 31 is installed on the frame 10, the left end of the chain transmission mechanism 31 can be moved to the left close to the center line of the frame 10, which relatively reduces the degree of right deviation of the center of gravity of the equipment, thereby reducing the risk of rollover. In addition, in conjunction with the arrangement of other mechanisms, the center of gravity of the equipment can be made as close to the center line of the frame 10 as possible.

[0058] The angle between the first side plate 321 and the second side plate 322 of the sorting partition 32 can be 40° to 50°, and more preferably, the angle can be 45°. Different angles will make the landing position 33 of the lotus seedlings different, and the 45° angle can make the second side plate 322 play a better guiding role for the lotus seedlings in both the seedling receiving state and the seedling dropping state.

[0059] In a more preferred embodiment, see Figure 7 and Figure 8, the ditching device 40 is arranged at the front end of the frame 10, and the ditching device 40 includes a parallelogram bracket 41, a telescopic rod 42 (such as an electric push rod or a cylinder, etc.) and a ditching plowshare 43. The parallelogram bracket 41 includes a frame vertical rod (which is a part of the frame 10), a connecting upper rod and a connecting lower rod parallel to each other, and a connecting vertical rod parallel to the frame vertical rod. The connecting upper rod and the connecting lower rod are both hinged to the frame vertical rod at one end and hinged to the connecting vertical rod at the other end. The ditching plowshare 43 is fixedly installed at the bottom end of the connecting vertical rod, and one end of the telescopic rod 42 is hinged to the frame 10 and the other end is hinged to the connecting upper rod or the connecting lower rod. In other embodiments, the ditching device 40 can also adopt other structures to realize the lifting function. At first, the furrowing device 40 is located at the initial position. When the planter reaches the designated position, the telescopic rod 42 extends to drive the parallelogram bracket 41 to extend to the working position, and the tip of the furrowing plowshare 43 extends into the soil. As the frame 10 moves forward, the furrowing plowshare 43 can perform continuous furrowing operations. At the same time, during the specific planting process, the planter can also set the operation mode of the electric push rod so that the furrowing plowshare 43 can be automatically lifted up for a certain distance after it drops a certain distance, which is conducive to timely discharge of the broken soil generated during the furrowing process, so as to reduce the resistance of the soil on the furrowing plowshare 43 during furrowing.

[0060] In addition, if Figure 8 and Fig. 9 As shown, the soil covering device 50 is arranged at the rear end of the frame 10, and the soil covering device 50 includes a soil covering motor 51, a screw rod 52, a nut type slide 53 sleeved on the screw rod 52, a mounting rod 54 arranged on the nut type slide 53, and a soil covering shovel 55 arranged on the bottom end of the mounting rod 54. The soil covering motor 51 can drive the screw rod 52 to rotate to drive the soil covering shovel 55 to move up and down. In other embodiments, the soil covering device 50 can also adopt other structures to achieve the lifting function. Among them, the soil covering shovel 55 can preferably be an eight-shaped shovel (with an eight-shaped cross section), with a large opening facing the front of the travel direction A and a small opening facing the rear of the travel direction A. The small opening on the soil covering shovel 55 can keep excess soil in place and will not take away too much soil during the travel process. At first, the soil covering device 50 is located at the initial position. When the planting machine travels to the designated position, the soil covering device 50 is driven by the soil covering motor 51, and the screw rod 52 rotates to move the nut type slide 53 downward, so as to realize the lowering of the soil covering shovel 55. After the soil covering shovel 55 is lowered to the working position, the soil around it is pushed into the ditch as the planting machine moves forward, so as to complete the burial. The soil covering device 50 can realize the function of fast and effective soil covering, and can perform continuous soil covering.

[0061] Taking into account the differences between the north and the south, dry land is mostly used to plant lotus roots in the north, while shallow paddy fields are mostly used to plant lotus roots in the south. The multifunctional lotus root planting machine also includes a seedling pressing device 60 that is liftably arranged on the frame 10. Based on the travel direction A of the frame 10, the seedling pressing device 60 is located behind the lotus seedling conveying device 30. The seedling pressing device 60 can be specifically located between the lotus seedling conveying device 30 and the soil covering device 50. At this time, the furrowing device 40 and the soil covering device 50 are both in their initial positions. After the lotus seedlings transported by the lotus seedling conveying device 30 fall to the ground, the seedling pressing device 60 can press the front half of the lotus seedlings into the mud (see Fig.10 , Fig.10 The upper layer where the lotus root seedlings are buried is water, and the lower layer is mud), while the back half is exposed from the soil, so that the lotus root seedlings are inserted obliquely into the mud at a certain angle, completing the process of planting lotus roots by the oblique insertion method.

[0062] See again Figure 7 and Figure 8 The seedling pressing device 60 includes a seedling pressing motor 61 (preferably a stepping motor), a crank connecting rod mechanism 62, a vertical slide rail 63 arranged on the frame 10, a slider 64 arranged on the vertical slide rail 63, a seedling pressing rod 65 arranged on the slider 64, and a seedling pressing plate 66 arranged on the bottom end of the seedling pressing rod 65. The seedling pressing motor 61 can drive the slider 64 to slide back and forth on the vertical slide rail 63 through the crank connecting rod mechanism 62 to drive the seedling pressing plate 66 to move up and down. At the beginning, the seedling pressing device 60 is located in the initial position. When the planting machine travels to the specified position, the seedling pressing motor 61 drives the seedling pressing plate 66 to move back and forth up and down to complete the seedling pressing action. As the planting vehicle moves forward, the seedling pressing plate 66 can be periodically pressed down and lifted, and then the seedling delivery speed of the lotus seedling conveying device 30 is adjusted to continuously complete the lotus root oblique insertion method planting.

[0063] Furthermore, in a more preferred embodiment, the seedling pressing device 60 also includes a detection element disposed on the frame 10, and the detection element is electrically connected to the seedling pressing motor 61, wherein the detection element can be an ultrasonic sensor, a laser sensor, or a visual detection camera, etc., to improve the efficiency of lotus root planting and reduce the damage to the lotus root seedlings. When the ultrasonic sensor detects the falling of the lotus root seedlings, the stepper motor rotates, driving the crank connecting rod mechanism 62, and the slider 64 performs a vertical translation movement on the vertical slide rail 63. The slider 64 drives the seedling pressing plate 66 to descend through the seedling pressing rod 65, pressing the front half of the lotus root seedling into the soil, so that the lotus root seedling is in an oblique insertion state, thereby realizing the use of the oblique insertion method to plant lotus roots in paddy fields.

[0064] The multifunctional lotus root planting machine of the present invention can fully realize automated lotus root planting according to different conditions of dry land and paddy field. When planting in dry land, the planting machine is loaded with lotus root seedlings and advances to the planting position. The ditching device 40 is used to open the ditch first. The cam 222 and the chain transmission mechanism 31 cooperate to transport the lotus root seedlings so that the lotus root seedlings fall into the planting ditch in turn. At the same time, the planting vehicle continues to move forward, and the soil covering device 50 completes the soil covering work and carries out the next planting. When planting in paddy field, the lotus root planting machine changes the planting mode, and the ditching device 40 and the soil covering device 50 are no longer used. After the cam 222 and the chain transmission mechanism 31 cooperate to make the lotus root seedlings fall into the farmland, the seedling pressing device 60 is used to press down the front section of the lotus root seedlings so that the lotus root seedlings are obliquely inserted into the field, completing the process of planting lotus roots by oblique insertion. The use of the above-mentioned equipment can reduce the loss of manpower and material resources, improve the survival rate of lotus root seedlings, greatly shorten the planting cycle, and realize large-scale mechanized lotus root planting. It has strong practicality and can also bring great economic benefits.
