Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0033] In addition, it should be noted that the connections involved in the present invention can be achieved by using conventional connection methods and do not involve any innovation.

[0034] The present invention relates to a lotus root planting and harvesting machine. When planting lotus roots, the soil must be irrigated and leveled to provide suitable humidity. Currently, harvesting lotus roots manually requires a lot of manpower and time. Shallow water lotus roots can be harvested directly in the water or after draining the water. Deep water lotus roots are generally more difficult to drain, so they are usually harvested while still wet.

[0035] The existing lotus root machines on the market can generally only harvest and cannot meet the planting function. Moreover, simply using a high-pressure water gun to impact the pond to make the lotus roots float to the surface during harvesting cannot achieve the collection of lotus roots. Lotus root planting and harvesting still requires a lot of manpower and time.

[0036] Based on the above reasons, the present invention provides a lotus root planting and harvesting integrated machine to solve the above-mentioned technical problems. Figures 1 to 6 The present invention is described in detail with reference to the structural diagram of FIG.

[0037] Example 1

[0038] The present invention provides a lotus root planting and harvesting integrated machine, such as Figure 1 and Figure 2 As shown, it includes a frame 1, a water gun 13, which is arranged at the front of the frame 1, and also includes a baffle-type conveying mechanism, a box 6, and a first lifting mechanism 16.

[0039] The baffle conveyor mechanism is arranged behind the water gun 13. The baffle conveyor mechanism includes a baffle conveyor belt 8 and a drive motor. The power output end of the drive motor is connected to the power input end of the baffle conveyor belt 8. The drive motor can realize forward and reverse rotation. When rotating forward, the baffle conveyor belt 8 runs forward, and when reversing, the baffle conveyor belt 8 runs reverse. The box 6 is used to store lotus roots. The box 6 is arranged behind the baffle conveyor belt 8. The side of the box 6 close to the baffle conveyor belt 8 has an outlet. A first baffle 15 is provided at the outlet. The top of the box 6 has an inlet. The first lifting mechanism 16 is arranged on the frame 1. The lifting end of the first lifting mechanism 16 is connected to the box 6 and is used to drive the box 6 to rise and fall to a first height and a second height.

[0040] like Figure 3 As shown, the frame 1 is made of plexiglass, with buoyancy tanks 2 made of EPS foam installed on either side. The buoyancy of the materials allows the entire machine to float on the water surface. During operation, the machine is driven forward by a user pushing on the armrests of frame 1.

[0041] When the box body 6 is located at the first height, the outlet is located above the baffle-type conveyor belt 8, the drive motor rotates forward, and the baffle-type conveyor belt 8 runs forward to realize lotus root planting.

[0042] When the box body 6 is located at the second height, the inlet is located below the baffle-type conveyor belt 8, the driving motor is reversed, and the baffle-type conveyor belt 8 runs in the reverse direction to achieve lotus root harvesting.

[0043] Two equal shafts 7 are provided in the middle of the frame 1. The left side of the shaft 7 is fixed to the frame 1 through a coupling 14 and a bearing seat 12. The right side of the shaft 7 is connected to the motor 4 through a coupling 14. The battery 5 and the motor 4 are fixed to the frame 1. The motor 4 is equipped with a battery 5. The shafts 7 are equipped with 16 identical synchronous pulleys 9, which are connected to two baffle conveyor belts 8 via the synchronous pulleys 9.

[0044] The motor 4 is a motor that can change direction. The battery 5 provides power to the motor 4 to rotate, thereby driving the baffle conveyor belt 8 to rotate. When the motor 4 rotates forward, it drives the baffle conveyor belt 8 to rotate forward. When the motor 4 rotates reversely, it drives the baffle conveyor belt 8 to reverse.

[0045] The main function of the baffle conveyor belt 8 is as follows: When the motor 4 rotates forward, it drives the shaft 7. The synchronous pulley 9, connected to the shaft 7 via a key, also rotates, driving the baffle conveyor belt 8 forward to complete the planting process. When the motor 4 rotates reversely, the baffle conveyor belt 8 also rotates in the reverse direction to complete the harvesting process. The battery 5 provides electrical energy, which is converted into mechanical energy by the motor 4 to power the equipment.

[0046] Working principle of this embodiment

[0047] like Figure 1 and Figure 2 As shown, during planting, the outlet of the box body is raised to above the baffle conveyor belt, and the lotus roots fall from the outlet onto the baffle conveyor belt. The baffle conveyor belt rotates forward to drive the lotus roots to move until they fall into the pond; during harvesting, the inlet of the box body is raised to below the baffle conveyor belt. As the frame moves forward, the lotus roots on the water surface enter the baffle conveyor belt. The baffle conveyor belt reverses and transports the lotus roots to the inlet so that the lotus roots enter the box body, thereby realizing both the planting and harvesting of lotus roots, and saving time and effort.

[0048] Example 2

[0049] like Figure 5 As shown, based on Example 1, this embodiment optimizes the box body 6. Two opposing limit slots are provided on the box body 6. The two limit slots are located on either side of the outlet. The slide is arranged in the vertical direction, and the two sides of the first baffle 15 are respectively arranged in the corresponding limit slots. A slide is fixedly installed on the inner bottom of the box body 6. The slide is arranged at an angle so that the side of the slide closer to the outlet is lower than the other side.

[0050] At the same time, the first lifting mechanism 16 connected to the box body 6 is specifically designed as follows: the first lifting mechanism 16 includes a first lifting rod 26, a second lifting rod 27, a first guide rail 29 and a second guide rail 28. The first guide rail 29 and the second guide rail 28 are both arranged horizontally, the first guide rail 29 is set at the bottom of the box body 6, and the second guide rail 28 is set on the frame 1. The first lifting rod 26 and the second lifting rod 27 are hinged, one end of the first lifting rod 26 is hinged to the frame 1, and the other end is slidably connected to the first guide rail 29, one end of the second lifting rod 27 is hinged to the box body 6, and the other end is slidably connected to the second guide rail 28.

[0051] The main function of box 6 is to store lotus root seedlings and mature lotus roots. When planting lotus roots, box 6 is lifted. Simultaneously, the first and second lifting rods of the first lifting mechanism 16 are moved along their respective guide rails, raising box 6. The lotus root seedlings are then placed through the inlet of box 6. Gravity forces the seedlings down the inclined slide to the outlet. The first baffle 15 controls the descent of the lotus root seedlings and their speed. The baffle is manually adjustable and, once adjusted, is secured by friction.

[0052] When harvesting lotus roots: lower the box 6, and the first lifting rod and the second lifting rod in the first lifting mechanism 16 move along their respective guide rails to lower the box 6. As the baffle conveyor belt 8 rotates, the lotus roots fall from the entrance to the box 6 to complete the harvest.

[0053] Working principle of this embodiment

[0054] like Figure 5As shown, when manually lifting the lotus roots, the first and second lifting rods simultaneously move leftward at one end of the guide rail, raising the box body upward and ensuring it reaches the working position for lotus root planting. When manually pressing the box body downward, the first and second lifting rods simultaneously move rightward at one end of the guide rail, lowering the box body downward and ensuring it reaches the working position for harvesting. The design of the first and second lifting rods and the guide rail provides excellent stability, ensuring that the object is not easily tilted or collapsed during the lifting process.

[0055] Example 3

[0056] like Figure 6 As shown, based on the above embodiment, this embodiment optimizes the height of the water gun. In this embodiment, a second lifting mechanism 17 is provided at the front end of the frame 1, and a water gun 13 is provided at the lifting end of the second lifting mechanism 17. A water pump 10 is provided at the bottom of the frame 1, and the inlet of the water pump 10 faces downward, and the water outlet of the water pump 10 is connected to the water gun 13.

[0057] Four integrated water guns 13 are placed at the front of the frame 1 , and the water pump 10 draws water from the pond to provide a water source for the water guns 13 .

[0058] The main function of the water gun 13 is to supply water through the water pump 10 and pressurize the water to form a certain impact force. It is ensured that a ditch can be flushed out of the soil during planting and the lotus roots can be flushed out of the water from the soil during harvesting.

[0059] In this embodiment, the second lifting mechanism 17 includes a gear 18, a rack 21, a second drive unit, a bracket 20, and a stopper 19. The gear 18 is rotatably connected to the frame 1, the output end of the second drive unit is connected to the gear 18, the stopper 19 is fixed to the frame 1, the rack 21 is slidably connected to the stopper 19, the rack 21 is meshed with the gear 18, the bracket 20 is fixedly connected to the rack 21, and the water gun 13 is disposed on the bracket 20. The second drive unit can be an electric motor.

[0060] The second lifting mechanism 17 drives the gear to rotate through the motor, thereby driving the rack connected to the water gun to move up and down to achieve the lifting of the water gun.

[0061] The second lifting mechanism 17 uses an electric motor as a power source. When working, the electric motor transmits power to the gear 18, which is engaged with the rack 21, and the rack 21 is constrained by a limiter to move only in the vertical direction.

[0062] Working principle of this embodiment

[0063] like Figure 6As shown, when the motor rotates forward, it drives the gear clockwise, causing the rack to move upward, driving the bracket upward and raising the water gun. When the motor rotates reversely, it drives the gear counterclockwise, causing the rack to move downward, driving the bracket downward and lowering the water gun. The rack and gear components are small and compact, and the gear and rack are highly adjustable, allowing for operation at varying water depths. The reversing motor also automates the up and down movement of the water gun.

[0064] Example 4

[0065] like Figure 4 As shown, based on the above embodiment, this embodiment further optimizes the lotus root harvesting method. In this embodiment, the baffle conveyor belt 8 is tilted so that its front end is lower than its rear end. The baffle conveyor belt 8 is provided with a number of blades along its length, and the blades are fixedly connected to the baffle conveyor belt 8.

[0066] In order to improve the harvesting efficiency and reduce omissions, a salvage assembly 3 is provided in front of the baffle conveyor belt 8. The salvage assembly 3 includes a salvage plate 25 and two sets of crank rocker mechanisms. The two sets of crank rocker mechanisms are arranged on the frame 1, and the two sets of crank rocker mechanisms are symmetrically arranged on the left and right sides of the baffle conveyor belt 8. Each set of crank rocker mechanisms includes a rocker. The two ends of the salvage plate 25 are respectively connected to a corresponding rocker. The salvage plate 25 is used to salvage the lotus root onto the baffle conveyor belt 8.

[0067] In this embodiment, the crank-rocker mechanism includes a crank 23, a connecting rod 24, and a rocker 22. One end of the crank 23 is hinged to the frame 1, one end of the rocker 22 is hinged to the frame 1, and both ends of the connecting rod 24 are respectively connected to the other end of the crank 23 and the rocker 22. The crank 23 of one set of the crank-rocker mechanism is connected to a first drive unit. The first drive unit can be an electric motor.

[0068] The main function of the salvaging component 3 is to salvage the lotus roots on the water surface onto the baffle conveyor belt 8 by utilizing the reciprocating motion of the rocker on the salvaging component 3 swinging up and down.

[0069] Working principle of this embodiment

[0070] like Figure 4 As shown, during operation, the motor drives the crank to rotate. This rotational motion is transmitted to the rocker via the connecting rod, driving the rocker and the salvage plate in a reciprocating arc-shaped quick return motion. The salvage plate's reciprocating arc-shaped quick return motion allows it to salvage lotus roots from the water and then rise to a certain height, allowing the roots to slide onto the conveyor belt for complete salvage. The crank and rocker's quick return feature allows the lotus roots to be salvaged slowly, but quickly reach the desired position after salvage is complete, allowing for the next salvage attempt. This reduces non-productive time and improves lotus harvesting efficiency.

[0071] Example 5

[0072] On the basis of the above embodiment, in order to improve the effect of lotus root planting and prevent the lotus root from floating on the water surface after planting, the lotus root is covered. Figure 2 As shown, in this embodiment, two second baffles 11 are provided at the bottom of the rack 1. The two second baffles 11 are symmetrically arranged on the left and right. The second baffles 11 are connected to the rack 1 through self-locking hinges, and the distance between the two second baffles 11 gradually decreases from front to back.

[0073] The second flap 11's main function is to fold using a 90° self-locking hinge. This hinge is self-locking and has a rigid tab in the middle. When the first flap is opened, the tab automatically presses against the vertically positioned hinge to prevent it from resetting. When closing the first flap, the tab must be manually pressed until it is parallel to the hinge.

[0074] Working principle of this embodiment

[0075] When the lotus seedlings fall into the flushed ditch, as the machine moves forward, the first baffles 11 on both sides of the lower body push the soil on both sides of the ditch into the ditch, covering the lotus seedlings and completing the planting.

[0076] The method for using the lotus root planting and harvesting machine provided by the present invention is as follows:

[0077] (1) Realization of planting function:

[0078] First, use the first lifting mechanism 16 to fix the box body 6 to the working area above the frame 1, so that the outlet of the box body 6 is higher than the baffle conveyor belt 8, and open the two second baffles 11 below the frame 1. According to different water depth settings, the height of the four water guns 13 is adjusted by the second lifting mechanism 17.

[0079] ① Spray: Start the water pump 10 switch, pump water from the pond through the water pump 10, and spray high-pressure water jets from the four front water guns 13. As manpower pushes the equipment forward, the soil in the pond is washed away to form a planting ditch.

[0080] ② Rotation: Turn the power switch of motor 4 to the forward rotation position, so that motor 4 drives shaft 7 to rotate forward, and then drives baffle-type conveyor belt 8 to rotate forward. Put the lotus seedlings into the upper entrance of box body 6, and slide them to the outlet of box body 6 through the inclined slide built into box body 6. At this time, gently lift the first baffle 15 in front of box body 6 to make the lotus seedlings fall onto the blades of baffle-type conveyor belt 8 one by one. The lotus seedlings rotate until they fall into the opened planting ditch, forming a reasonable dense planting with equal distance between the front and the back.

[0081] ③ Press: When the lotus seedling on the previous leaf falls into the ditch, it will float upwards, so the next leaf will follow and press the lotus seedling to prevent it from floating.

[0082] ④ Bury: As the machine moves forward, the two second baffles 11 at the rear of the frame 1 cover the soil on both sides of the mud channel on the lotus seedlings to bury them.

[0083] At this point the planting function is fully realized.

[0084] (2) Implementation of harvesting function:

[0085] First, the box body 6 is lowered to the lower working area through the first lifting mechanism 16, and the two second baffles 11 below the frame 1 are closed. According to different water depth settings, the heights of the four water guns 13 are adjusted through the second lifting mechanism 17.

[0086] ① Spray: Start the water pump 10 switch, pump water from the pond through the water pump 10, and spray high-pressure water jets from the four water guns 13 in front. As manpower pushes the equipment forward, the mud on the surface of the lotus root in the pond is washed away, and the lotus root floats on the water surface due to buoyancy.

[0087] ② Turn on the power switch of motor 4 to the reverse position, so that motor 4 drives shaft 7 to reverse, and then drives baffle conveyor belt 8 to reverse.

[0088] ③ Push: The motor rotates and drives the crank 23 to rotate counterclockwise for a full circle through the salvage component 3, driving the connecting rod 24 to move horizontally, and then driving the rocker 22 and the salvage plate 25 to move back and forth to realize the salvage action. The salvage plate 25 pushes the lotus root that has floated to the surface to the gap between the lotus root and the previous leaf.

[0089] ④ Collection: As the salvaging component 3 is scooped up, the lotus root is steadily scooped up onto the baffle conveyor belt 8. As the baffle conveyor belt 8 is reversed, the lotus root moves toward the rear box 6 until it falls into the box 6 below, completing the work requirement of collecting the lotus root.

[0090] The above disclosure is only a preferred specific embodiment of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
