Exemplarily, the working platform is a rectangular flat plate, the four legs 1-3 are respectively connected to the four corners of the working platform through bearings, so that the four legs 1-3 can rotate relative to the working platform, the four walking wheels 1-1 are respectively connected to the four legs 1-3 through their axles, bearings are arranged at the connection between the axles and the legs 1-3, the axles are connected to the first drive motor 1-2 through a coupling, so that they can be driven by the first drive motor 1-2, and the first drive motor 1-2 is fixedly mounted on the legs 1-3. In addition, it should be noted that the walking wheel 1-1 adopts a Mecanum wheel, which is composed of a group of rotating rollers evenly arranged around the wheel hub. The axes of these rollers are at a certain angle (generally 45°) to the axis of the wheel hub, so that the wheel can achieve all-round movement. The working principle of the Mecanum wheel is based on the principle of vector superposition. When each small wheel rotates, a vector is generated. The direction and length of these vectors are determined by the rotation speed and direction. The vectors generated by all small wheels are superimposed to obtain a synthetic moving vector, thereby realizing the movement of the robot. Through the walking mechanism 1 set in this way, it is convenient for the entire tea seedling planting machine to move freely in the tea planting area.

A movable groove is provided on the working platform. The movable groove runs through the working platform. The movable groove is provided to facilitate the planting mechanism 6, the drilling mechanism 4 and the watering and fertilizing mechanism 5 to pass through the working platform, so that the area below the working platform can be drilled, planted and watered and fertilized. It should be noted that the upper platform 3-4 and the lower platform 3-5 are both flat plate structures, which can be circular plates or polygonal plates. It should be noted that if the support platform affects the subsequent placement of the seedlings into the cylinder 6-4 of the planting mechanism 6 or affects the connection of the watering and fertilizing mechanism 5 with the water tank 2, the support plate 3-2 of the support platform can be replaced with a rod bracket.

The steering gear drives the movable rod to move within a certain range, and pulls the opening and closing cover 6-5 to move on the swing shaft 6-6.

[0039] Exemplarily, the cylinder 6-4 is a cylindrical hollow cylinder, the top opening of which is a tea seedling entrance 6-4-1 for placing tea seedlings, and the bottom opening is a tea seedling outlet for transporting the tea seedlings in the cylinder 6-4 to the planting holes drilled by the drilling mechanism 4; wherein the upper platform 3-4 is provided with a through hole for the cylinder 6-4 to extend into, so that the tea seedling entrance 6-4-1 of the cylinder 6-4 is exposed to the outside, which is convenient for placing tea seedlings, and the lower platform 3-5 is also provided with a through hole, which is convenient for the cylinder 6-4 to pass through the lower platform 3-5; the first guide rod 6-3 is a cylindrical rod, and the two ends of the first guide rod 6-3 are respectively connected to the upper platform 3- 4 and the lower platform 3-5 are fixed (can be welded or screwed), the two ends of the first screw rod 6-2 are respectively fixed to the upper platform 3-4 and the lower platform 3-5, the number of the first guide rods 6-3 is two, the two first guide rods 6-3 are symmetrically distributed on both sides of the first screw rod 6-2, the first lifting platform is provided with two sliding holes to cooperate with the two first guide rods 6-3, so that when the first lifting motor 6-1 drives the first screw rod 6-2 to rotate, the first lifting platform can slide along the two first guide rods 6-3, and the two first guide rods 6-3 can limit the first lifting platform from rotating with the first screw rod 6-2.

[0042] like Figure 1-6 As shown in , 8, the watering and fertilizing mechanism 5 is arranged on the rotating mechanism 3; the watering and fertilizing mechanism 5 includes a delivery pipe 5-5, a third lifting assembly and a valve, the delivery pipe 5-5 is connected to the outlet pipe of the water tank 2, the delivery pipe 5-5 is fixed at the movable end of the third lifting assembly, and the valve is arranged at the outlet end of the delivery pipe 5-5; the third lifting assembly and the valve are both electrically connected to the control unit. Exemplarily, the delivery pipe 5-5 is prepared by cutting a stainless steel pipe. By using a rigid delivery pipe 5-5, it can be ensured that the delivery pipe 5-5 will not be affected by external forces, resulting in the delivery pipe 5-5 not extending to the planting hole, thereby preventing the water and fertilizer delivered by the delivery pipe 5-5 from not being in place.

[0043] The third lifting assembly includes a third lifting motor 5-1, a third screw rod 5-2, a third guide rod 5-3 and a third lifting platform 5-4.

[0044] The first lifting assembly, the second lifting assembly and the third lifting assembly have the same structure and the same working mode, but the installation positions are different, driving different structures to lift and lower relative to the working platform. For example, the corresponding lifting motors are fixed on the upper platform 3-4, the corresponding screw rods are fixedly connected to the output shafts of the corresponding lifting motors, and the two ends of the corresponding guide rods are fixed on the upper platform 3-4 and the lower platform 3-5, so no further details will be given here.

[0045] The control unit is arranged on the traveling mechanism 1, and is used to control the operation of the traveling mechanism 1, the rotating mechanism 3, the planting mechanism 6, the drilling mechanism 4 and the watering and fertilizing mechanism 5; the control unit is an existing controller and will not be described in detail here.

[0046] like Figure 1-2 As shown, the water tank 2 is arranged on the walking mechanism 1, and the water tank 2 is connected to the watering and fertilizing mechanism 5 through a pipeline; illustratively, the water tank 2 is fixed to the working platform by screws, the water tank 2 is a hollow cubic container (it can also be a container of other structures, such as a cylinder), a water inlet is arranged on the top of the water tank 2, a water outlet is arranged on the side wall of the water tank 2, the water outlet is connected to a pipeline, the outer end of the pipeline is connected to a water pump, the water pump is connected to a pipeline connected to the delivery pipeline 5-5, so that the water and fertilizer in the water tank 2 can be transported to the delivery pipeline 5-5.

[0047] Among them, the planting mechanism 6, the drilling mechanism 4 and the watering and fertilizing mechanism 5 are distributed in an equilateral triangle on the rotating mechanism 3. It should be noted that the geometric center of the equilateral triangle coincides with the center of the cross section of the rotating shaft 3-6 of the rotating mechanism 3. By using the three mechanisms distributed in an equilateral triangle, each mechanism can be placed in the planting position by controlling the rotating mechanism 3 to rotate 120 degrees each time, without the need to reposition each planting step, thereby improving the planting efficiency and having a high degree of automation.

[0048] Working principle: After the walking mechanism 1 drives the entire tea seedling planting machine to move to the tea seedling planting area, according to the planting area that has been divided on the ground, the walking mechanism 1 drives the tea seedling planting machine to move to the planting area, and the control unit controls the second lifting motor 4-5 to start, the second lifting motor 4-5 drives the second screw rod 4-3 to rotate, the second lifting platform 4-4 starts to descend, and the third drive motor 4-1 descends with the second lifting platform 4-4; the control unit controls the third drive motor 4-1 to start, and the drill bit 4-6 rotates with the rotation of the third drive motor 4-1 to start drilling holes in the planting area. After the drill bit 4-6 has drilled a hole, the control unit starts to start the third drive motor 4-1. The control unit controls the second lifting motor 4-5 to rotate in the opposite direction, and the second lifting platform 4-4 rises until the drill bit 4-6 is immediately on the ground. The control unit controls the second lifting motor 4-5 to turn off and controls the third drive motor 4-1 to turn off; that is, the drilling mechanism 4 digs a planting hole for planting tea seedlings on the ground, and the control unit controls the second drive motor 3-3 of the rotating mechanism 3 to start, driving the rotating platform to rotate 120 degrees, the drilling mechanism 4 moves away from the drilling position, and the planting mechanism 6 rotates to the planting hole. At this time, the control unit controls the first lifting motor 6-1 to start, the screw rotates, and the first lifting platform begins to descend, and the cylinder installed on the first lifting platform 6-4 also starts to descend. When it descends to 3-5cm from the ground, the first lifting motor 6-1 is turned off (a distance sensor can be set on the cylinder 6-4 to detect the distance between the cylinder 6-4 and the ground. When the detected distance reaches a preset threshold, a signal is sent to the control unit, and the control unit controls the first lifting motor 6-1 to be turned off). The control unit controls the steering gear to start, and the output shaft of the steering gear drives the movable rod to move. The movable rod drives the opening and closing cover 6-5 to swing with the swing shaft 6-6 as the fulcrum. The tea seedling outlet of the cylinder 6-4 is opened, and the tea seedlings in the cylinder 6-4 slide from the cylinder 6-4 into the planting hole, and then the control unit continues The servo is controlled to work, and the servo drives the movable rod to move, driving the opening and closing cover 6-5 to close the tea seedling outlet. The control unit controls the first lifting motor 6-1 to start, driving the cylinder 6-4 to reset; then the control unit controls the second drive motor 3-3 to drive the rotating platform to rotate 120 degrees, and the control unit controls the third lifting motor 5-1 to drive the third screw rod 5-2 to rotate. The rotation of the third screw rod 5-2 causes the third lifting platform 5-4 to descend, and the conveying pipe 5-5 to water and fertilize the planting hole. Then the control unit controls the conveying pipe 5-5 to reset, completing the entire process of tea seedling planting, and continuing to plant tea seedlings in the next planting area according to this process.

[0049] It should be noted that the fertilizer used in the above embodiment is a water-soluble fertilizer, which is a multi-component compound fertilizer that can be completely soluble in water. It can be quickly dissolved in water, more easily absorbed by crops, and its absorption and utilization rate is relatively high. This fertilizer can not only be applied through soil irrigation to allow the roots of plants to fully contact the fertilizer, but can also be applied through foliar spraying, drip irrigation, and soilless cultivation, saving irrigation water and improving the utilization rate of fertilizer. In addition, the application of water-soluble fertilizers also includes seed soaking and root dipping, irrigation and fertilization, etc. These methods save water and fertilizer, and also make plants absorb quickly; therefore, in the above embodiment, the water-soluble fertilizer is first mixed with the water in the water tank 2, so that the two steps of watering and fertilization are combined into one step to improve the planting efficiency.

[0050] It should be noted that, in the present embodiment, the tea seedlings are placed one by one into the cylinder 6-4 by the staff, and the tea seedlings can be arranged in advance and placed on the working platform, and the opening and closing cover 6-5 can be provided with a pressure sensor, and the control unit can know whether there are tea seedlings in the cylinder 6-4 according to the pressure signal detected by the pressure sensor, thereby avoiding that there are no tea seedlings in the cylinder 6-4 and the opening and closing cover 6-5 is controlled to open and close, resulting in the tea seedlings not being able to be planted in the planting hole.

[0051] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
