[0028] See also Figure 1-Figure 4 A field sowing device includes a mounting frame 1 and a mounting plate 5. The mounting frame 1 is mounted on a mobile vehicle. When the mobile vehicle moves in the field, it drives the sowing device to move, thereby sowing. This is a prior art and will not be described in detail here. A transversely arranged telescopic mechanism 2 is connected between the mounting frame 1 and the mounting plate 5. A plurality of sowing mechanisms 4 are arranged on the telescopic mechanism 2. The telescopic mechanism 2 adjusts the distance between two adjacent sowing mechanisms 4, thereby adjusting the distance between two holes to meet different usage requirements. The sowing mechanism 4 includes a seed storage barrel 402, and a seed delivery barrel 4021 is arranged below the seed storage barrel 402. The seed delivery barrel 4021 is provided with an adjustment part.

[0029] The mounting frame 1 and the mounting plate 5 are respectively provided with mounting blocks, and a telescopic rod 3 is arranged between the two mounting blocks, and the telescopic rod 3 is arranged horizontally. During the operation of the telescopic mechanism 2, the telescopic rod 3 is extended and retracted at the same time, thereby enhancing the stability of the device.

[0030] like Figure 1 , Figure 3 , Figure 4The sowing mechanism 4 further includes a fixed frame 401, a connecting shell 403 and two arc-shaped plates 404. The fixed frame 401 is arranged on the telescopic mechanism 2. The fixed frame 401 is provided with the seed storage barrel 402 through the connecting plate. The seed storage barrel 402 is arranged vertically. The seed storage barrel 402 is connected to the seed delivery barrel 4021. The seed storage barrel 402 is communicated with the seed delivery barrel 4021. The connecting shell 403 is arranged at the bottom of the seed storage barrel 402. The seed delivery barrel 4021 is located inside the connecting shell 403. A cavity is arranged between the two arc-shaped plates 404. The seed delivery barrel 4021 is communicated with the cavity. One of the arc-shaped plates 404 is fixedly connected to the bottom of the connecting shell 403. A groove is arranged inside the connecting shell 403. A cylinder 405 is arranged horizontally inside the groove. The piston rod of the cylinder 405 is connected to a push plate 406. The push plate 406 is fixedly connected to the other arc-shaped plate 404. The piston rod of the cylinder 405 is extended and retracted, driving the push plate 406 to move, and then driving the other arc plate 404 to move.

[0031] like Figure 4 , the adjustment part includes a second motor 4031, the second motor 4031 is arranged on the connecting shell 403, the output end of the second motor 4031 is connected to a cam 4032 through a connecting shaft, the cam 4032 is located at the bottom of the seed barrel 4021, for shielding the seed barrel 4021, and the axial direction of the cam 4032 is vertically arranged. The seed storage barrel 402, the seed barrel 4021, the connecting shell 403 and the two arc-shaped plates 404 are connected in sequence from top to bottom, the cam 4032 is located at the bottom of the seed barrel 4021, and the cam 4032 shields the bottom of the seed barrel 4021. The second motor 4031 runs, driving the cam 4032 to rotate, and adjusting the cam 4032 to shield the opening of the seed barrel 4021 to a preset size to meet the needs of sowing different types of crops (such as wheat, peanuts, etc.) (the size of the opening of the seed barrel 4021 is adjusted according to the diameter of different types of crops to control the number of sowing grains, thereby facilitating sowing). Figure 1 , Figure 2, the telescopic mechanism 2 includes two first connecting rods 21, a plurality of connecting frames connected end to end in sequence, two third connecting rods 23 and a driving unit; one end of the two first connecting rods 21 is respectively rotatably arranged on the mounting frame 1 through a rotating shaft, the number of the connecting frames is consistent with the number of the sowing mechanism 4, and both are two, and more can be set in actual operation. The connecting frame includes two second connecting rods 22 arranged to rotate crosswise, the other end of the first connecting rod 21 is respectively hinged to one end of the second connecting rod 22 of the first connecting frame, the second connecting rods 22 of two adjacent connecting frames are hinged one by one front and back, the second connecting rod 22 of the last connecting frame is hinged to one end of the corresponding third connecting rod 23, and the other end of the third connecting rod 23 is hinged to the mounting plate 5. The telescopic mechanism 2 is similar to the principle of a telescopic hanger, which will not be repeated here. The fixed frame 401 is correspondingly arranged at the intersection of the two second connecting rods 22 (here is the midpoint of the two second connecting rods 22).

[0032] like Figure 1 The driving unit includes two meshing gears 20, which are respectively arranged on the rotating shafts, one of which passes through the mounting frame 1 and is connected to a first motor 201. The first motor 201 runs, driving one of the gears 20 to rotate, and then driving one of the first connecting rods 21 to rotate, one of the gears 20 rotates while driving another gear 20 to rotate, and the other gear 20 drives another first connecting rod 21 to rotate, so that the ends of the two first connecting rods 21 away from the mounting frame 1 rotate toward each other around the mounting frame 1, thereby driving the ends of the two second connecting rods 22 in the connecting frame close to the mounting frame 1 to rotate toward each other, so that the connecting frame is stretched horizontally, thereby lengthening the distance between the two adjacent sowing mechanisms 4, and making the first motor 201 run in the reverse direction, so that the distance between the two adjacent sowing mechanisms 4 is shortened, thereby meeting different usage requirements.

[0033] In the initial state, the two arc plates 404 are in contact, and the seeds will not fall. When the sowing device is used, the distance between the sowing mechanisms 4 is adjusted by the telescopic mechanism 2, the second motor 4031 is operated, the cam 4032 is driven to rotate, and the size of the bottom opening of the seed delivery cylinder 4021 is adjusted. The seeds are placed in the seed storage cylinder 402, the seeds enter the seed delivery cylinder 4021, and fall into the cavity between the two arc plates 404 through the connecting shell 403, so that the piston rod of the cylinder 405 is contracted, and the push plate 406 and the arc plate 404 connected thereto are driven to approach the fixed end of the cylinder 405, so that the two arc plates 404 are separated, so that the seeds fall, and the piston rod of the cylinder 405 is extended, so that the two arc plates 404 are in contact, and the seeds no longer fall. So far, sowing can be carried out while the device is moving.
