[0039] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See Figure 1 The green onion planter comprises a tractor 1. Assume that the moving direction of the tractor 1 is along Figure 1 In the X direction, Figure 1 From left to right.

[0041] In a top view, the chassis of the tractor 1 is assumed to be rectangular, the center line of the chassis parallel to the X direction is line G, and the surface passing through line G and along the vertical direction is surface P.

[0042] Two plowshares are fixed to the lower surface of the right end of the chassis, and the two plowshares are symmetrically arranged along the surface P.

[0043] The upper surface of the chassis is fixedly connected to a frame 2, on which a lifting assembly 3 is provided. Figure 2 , the lifting assembly 3 comprises:

[0044] The non-rotating shaft end of the lifting motor 31 is fixed on the frame 2, and the rotating shaft of the lifting motor 31 is along the Y direction; the Y direction is perpendicular to the X direction;

[0045] Worm 32 (see Figure 1 ), which is fixedly connected to the rotating shaft of the lifting motor 31, and the axis of the worm 32 coincides with the axis of the rotating shaft of the lifting motor 31.

[0046] The three rotating rods are rotatably connected to the chassis respectively, and the axes of the three rotating rods are arranged vertically. When viewed from the axes of the rotating rods, the axes of the three rotating rods are not in a straight line.

[0047] The three linkage gears 36 are fixed on the corresponding rotating rods respectively, and the axes of the linkage gears 36 coincide with the axes of the corresponding rotating rods.

[0048] The worm wheel 35 is fixedly connected to one of the rotating rods, the axis of the worm wheel 35 coincides with the axis of the rotating rod, and the worm wheel 35 meshes with the worm 32. The rotating rod connected with the worm wheel 35 is the main rotating rod 33, and the other two rotating rods are auxiliary rotating rods 34.

[0049] The lifting plate 37 is sleeved on the two auxiliary rotating rods 34 at the same time, and the lifting plate 37 can slide along the axis of the rotating rod. The lifting plate 37 is threadedly connected to one of the auxiliary rotating rods 34 and can generate relative rotation with the other auxiliary rotating rod 34;

[0050] The linkage chain 38 meshes with the three linkage gears 36 at the same time.

[0051] The lifting motor 31 rotates the main rotating rod 33 through the worm gear 35 and the worm 32. The main rotating rod 33 drives the two auxiliary rotating rods 34 to rotate through three linkage gears 36 and a linkage chain 38. Restricted by the two auxiliary rotating rods 34, the lifting plate 37 cannot rotate and can only move along the axis of the auxiliary rotating rods 34. Because one of the auxiliary rotating rods 34 is threadedly engaged with it, the rotation of the auxiliary rotating rod 34 will drive the lifting plate 37 to be lifted and lowered.

[0052] The lifting plate 37 is provided with a trenching assembly 4, which is lifted and lowered by the lifting assembly 3. A through hole is provided on the chassis for the trenching assembly 4 to pass through, and the trenching assembly 4 can contact the ground through the through hole. The trenching assembly 4 can achieve the purpose of trenching at different depths by lifting and lowering. The trenching assembly 4 is located on the left side of the plow, and the trenching assembly 4 includes:

[0053] The non-rotating shaft end of the trenching motor 41 is fixedly connected to the lifting plate 37; the rotating shaft axis of the trenching motor 41 is along the Y direction.

[0054] The driving gear 42 is fixed on the rotating shaft of the trenching motor 41, and the axis of the driving gear 42 coincides with the axis of the rotating shaft of the trenching motor 41;

[0055] The connecting frame 43 is fixed on the lower surface of the lifting plate 37; the connecting frame 43 passes through the through hole.

[0056] A trenching shaft 44 is rotatably connected to the connecting frame 43, and the axis of the trenching shaft 44 is along the Y direction;

[0057] The driven gear 45 is fixedly connected to the trenching shaft 44 , and the axis of the driven gear 45 coincides with the axis of the trenching shaft 44 .

[0058] The groove grinding disc 46, in this embodiment, is in the shape of a disc and is fixedly connected to the groove rotating shaft 44, and the axis of the groove grinding disc 46 coincides with the axis of the groove rotating shaft 44. The groove grinding disc 46 is located on the left side of the plow. The groove grinding disc 46 is used to contact the ground, and the diameter of the groove grinding disc 46 is greater than the diameter of the driven gear 45, which is to prevent the driven gear 45 from contacting the ground.

[0059] The trenching chain 47 is meshed with the driving gear 42 and the driven gear 45 at the same time.

[0060] After the trenching motor 41 rotates, the trenching motor 41 drives the driven gear 45 to rotate through the driving gear 42 and the trenching chain 47, and the driven gear 45 causes the trenching shaft 44 and the trenching grinding disc 46 to rotate as a whole. After the trenching grinding disc 46 contacts the ground, as the tractor 1 moves forward, the trenching grinding disc 46 continuously rotates and trenches on the ground along the X direction.

[0061] See Figure 1 The frame 2 is provided with two water spraying and medicine spraying assemblies 5, and the two water spraying and medicine spraying assemblies 5 are symmetrically arranged along the plane P. The water spraying and medicine spraying assembly 5 is located on the left side of the lifting assembly 3 and also on the left side of the ditching assembly 4. The water spraying and medicine spraying assembly 5 includes:

[0062] The storage tank 51 is fixedly connected to the vehicle frame 2. In this embodiment, the storage tank 51 is cylindrical, with its axis arranged vertically, and a cavity for containing water or medicine is provided inside the storage tank 51.

[0063] The air pump 52 is fixedly connected to the vehicle frame 2. The air outlet of the air pump 52 is connected to the upper end surface of the storage tank 51 through a pipeline, and the air outlet of the air pump 52 is communicated with the cavity. The air pump 52 can be, but is not limited to, a micro air pump 52 of model TLN11-4A1, which is an existing product and can be purchased directly.

[0064] The filling port 53 is provided at the upper end of the storage tank 51. A sealing plug for sealing the filling port 53 is threadedly connected to the filling port 53.

[0065] The nozzle 54 is connected to the lower side wall of the storage tank 51 through a pipeline, and one end of the nozzle 54 connected to the storage tank 51 is connected to the cavity, and the nozzle 54 is fixed on the vehicle frame 2. A valve for controlling the opening and closing of the nozzle 54 is installed on the nozzle 54.

[0066] Because the air outlet of the air pump 52 is located at the upper end of the storage tank 51, when the air pump 52 inflates the storage tank 51, the water is concentrated at the upper end of the storage tank 51. After the valve on the nozzle 54 is opened, the air pressure sprays the water in the storage tank 51 out from the nozzle 54 at the lower end of the storage tank 51.

[0067] Two sets of seedling dropping assemblies 6 are installed on the frame 2, and the two sets of seedling dropping assemblies 6 are symmetrically arranged along the plane P. The seedling dropping assembly 6 is located on the left side of the ditching assembly 4. Figure 1 The seedling dropping component 6 includes:

[0068] The onion seedling placing frame 61 is fixed on the vehicle frame 2. In this embodiment, the onion seedling placing frame 61 is a rectangular frame, and an opening is provided on the left side of the onion seedling placing frame 61, and the opening is used for guiding the chain-type paper book 63 containing the onion seedlings below out of the onion seedling placing frame 61.

[0069] The onion seedling guide groove plate 62 is fixed on the vehicle frame 2. The left end of the onion seedling guide groove plate 62 is low, and the right end is high; the right end of the onion seedling guide groove plate 62 faces the opening of the onion seedling placement frame 61, and the chain-type paper book 63 drawn out from the opening can enter the onion seedling guide groove plate 62, and be led from the onion seedling guide groove plate 62 to the grooves opened on the ground. In this embodiment, there are two onion seedling guide groove plates 62.

[0070] See Figure 3 The chain-type paper book 63 is used for cultivating the onion seedlings. The cultivated onion seedlings are placed in each groove of the chain-type paper book 63, maintaining a certain distance. The chain-type paper book 63 is a prior art and can be directly purchased online. The chain-type paper book 63 containing the onion seedlings is curled up and placed in the onion seedling placement frame 61. Because the chain-type paper book 63 is made of paper, it can be curled up.

[0071] The width of the left end of the onion seedling guide slot 62 along the Y direction is just about equal to the unit width of the chain paper book 63. Therefore, the chain paper book 63 can only fall in the vertical state in the onion seedling guide slot 62 (i.e. Figure 3 The onion seedlings that are led to the ground can keep their roots at the bottom.

[0072] The free end (i.e., the left end) of the curled chain paper roll 63 passes through the onion seedling guide groove plate 62 and is guided to the ground by the onion seedling guide groove plate 62, so as to ensure that the onion seedlings on the chain paper roll 63 are placed with their roots downward on the onion seedling guide groove plate 62. Since the free end of the chain paper roll 63 is in the groove on the ground, and the friction between the free end of the chain paper roll 63 and the ground is large, the free end of the chain paper roll 63 will not move; as the tractor 1 moves forward, the chain paper roll 63 in the onion seedling placement frame 61 is continuously unwound, and finally, as the tractor 1 moves forward, the chain paper roll 63 in the onion seedling placement frame 61 is all laid in the groove on the ground.

[0073] The left end of the onion seedling guide slot plate 62 is rotatably connected to a plurality of soil covering wheels 7, and the axis of the rotating shaft of the soil covering wheel 7 is along the Y direction. In this embodiment, there are four soil covering wheels 7, which are arranged in groups of two, and each group of soil covering wheels 7 is arranged in a one-to-one correspondence with the onion seedling guide slot plate 62. The two soil covering wheels 7 in each group of soil covering wheels 7 are respectively located on both sides of the corresponding onion seedling guide slot plate 62 along the Y direction.

[0074] As the tractor 1 moves, because each set of soil covering wheels 7 is located on both sides of the corresponding onion seedling guide groove plate 62 along the Y direction, the soil on both sides of each onion seedling guide groove plate 62 along the Y direction is blocked by each set of soil covering wheels 7. Also, due to the deadweight of the soil covering wheels 7, after the soil below its surface is compacted, the two soil covering wheels 7 squeeze the soil between them, so as to achieve the purpose of covering the soil between the two soil covering wheels 7.

[0075] The use process of this device is:

[0076] First, the green onion seeds are cultivated in the grooves of the chain paper book 63, and the cultivated green onion seedlings are as follows. Figure 3 The chain paper book 63 is rolled up and placed in the green onion seedling placement frame 61 .

[0077] Then, the operator remotely controls the device to move to the planting site. First, the lifting assembly 3 is started to ensure that the furrowing assembly 4 can contact the ground. Then, the coulter is installed and the furrowing assembly 4 is turned on. The operator remotely controls the device to move a certain distance in the X direction to ensure that a certain length of furrow has been dug on the ground.

[0078] Then, the left end of the chain paper book 63 is placed in the groove dug on the ground after being limited by the left end of the onion seedling guide groove plate 62 from the opening.

[0079] Finally, the remote control moves the device along the X direction. As the device moves continuously, the onion seedling placement frame 61 is continuously unwound, and the onion seedlings in the chain paper book 63 are laid in the groove. The rolling of the covering wheel 7 will pile up the soil along the Y side of the groove opened between the two covering wheels 7, completing the simple covering. Based on common sense, the onion planting does not need to be buried too deep, so the simple covering can complete the covering work.

[0080] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
