[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0020] like Figure 1-3As shown, an adjustable spacing crop sowing machine is provided in the embodiment, including a vehicle body 1, a material box 2 and a sowing mechanism 3. The vehicle body 1 is provided with a material box 2 for containing seeds, and a sowing mechanism 3 is provided below the material box 2. The sowing mechanism 3 includes a support frame 31, a slide rail 32, a slider 33, a sowing tube 34, a retractable hose 35, a connecting rod 36, a hinge block 37 and a fixing member 38. The support frame 31 is fixed on the vehicle body 1, and a horizontally arranged slide rail 32 is fixed on one side of the support frame 31. More than two sliders 33 are slidably connected to the slide rail 32. A sowing tube 34 is vertically arranged on the slider 33, and the top of the sowing tube 34 is connected to the bottom of the material box 2 through a retractable hose 35. A hinge block 37 is provided between two adjacent sliders 33. Two connecting rods 36 are hinged on the hinge block 37, and the free ends of the two connecting rods 36 are respectively hinged to one of the sliders 33. A fixing member 38 is provided on the hinge block 37. In this embodiment, the material box 2 is a funnel-shaped structure, which can prevent seeds from piling up in the box, and a cover is provided on the top of the material box 2, which can close the top opening of the material box 2 and play a role in dust and moisture prevention. The sowing mechanism 3 is set up to perform sowing operations, wherein the support frame 31 is fixedly mounted on the vehicle body 1 to play a supporting role; the slider 33 can slide on the slide rail 32 in the front and rear directions, and the top surface of the slider 33 should be higher than the top surface of the support frame 31 to avoid the connecting rod 36 from interfering with the support frame 31 during the rotation process; the sowing tube 34 is provided with an electric control valve, which can control the on and off of the sowing tube 34, thereby achieving the effect of controlling the sowing time and sowing amount; the retractable hose 35 is set up to automatically extend or shorten as the position of the sowing tube 34 moves, and has good adaptability; the hinge block 3 7 is slidably connected to the support frame 31 and can slide arbitrarily on the support frame 31. The two ends of the connecting rod 36 are respectively connected to the hinge block 37 and the slider 33, which can connect two adjacent sliders 33 into one, and the distance between the two sliders 33 can be adjusted by pushing the hinge block 37, thereby achieving the purpose of adjusting the distance between two adjacent sowing tubes 34; the fixed member 38 is set to fix the hinge block 37 on the support frame 31, thereby fixing the position of the sowing tube 34 to prevent the position of the sowing tube 34 from being offset due to factors such as device vibration during sowing, thereby ensuring the sowing quality. In addition, a partition is also set in the material box 2, so as to separate a plurality of chambers in the material box 2, each of which can be used to place different seeds, and the top of each retractable hose 35 is respectively connected to one of the chambers, so that each sowing tube 34 can be used to sow different seeds.

[0021] Specifically, the fixing member 38 includes a support plate 381, a rotating handle 382, ​​a threaded shaft 383 and a rubber pad 384. The support plate 381 is fixed on the hinge block 37. The threaded shaft 383 is threadedly connected to the support plate 381. The top of the threaded shaft 383 is connected to the rotating handle 382, ​​and the bottom of the threaded shaft 383 is connected to the rubber pad 384. In this embodiment, the support plate 381 is horizontally arranged on the side of the hinge block 37 away from the slide rail 32, and one end of the support plate 381 is fixedly connected to the hinge block 37. The rotating handle 382 can drive the threaded shaft 383 to rotate, and then can control the rubber pad 384 to rise or fall. When the rubber pad 384 abuts against the end surface of the support frame 31, the friction force can be used to fix the hinge block 37 and the support frame 31 as a whole.

[0022] Specifically, the slider 33 is also provided with a height adjustment member 39, which includes an L-shaped side plate 391, a rotating gear 392, a rack 393 and a knob 394. The L-shaped side plate 391 is fixed to the top of the slider 33, and the rotating gear 392 is rotatably connected to the L-shaped side plate 391. The rack 393 is fixed to the outer wall of the sowing tube 34, and the rotating gear 392 is meshed with the rack 393. A knob 394 is also fixed to one side of the rotating gear 392. In this embodiment, the height adjustment member 39 is used to adjust the height of the sowing tube 34 to adapt to different terrains. Among them, the L-shaped side plate 391 is located on one side of the sowing tube 34, and the bottom end of the L-shaped side plate 391 is fixedly mounted on the slider 33; the knob 394 is arranged coaxially with the rotating gear 392, so that when the knob 394 is rotated, the rotating gear 392 can be driven to rotate synchronously, and then the sowing tube 34 is driven to rise or fall by the structure in which the rotating gear 392 and the rack 393 are meshed with each other, so as to achieve the purpose of adjusting the height of the sowing tube 34. In addition, when sowing, the user should control the bottom end of the sowing tube 34 to be slightly higher than the notch of the ground sowing groove through the height adjustment member 39 to ensure that the seeds can completely fall into the ground sowing groove.

[0023] Specifically, a sliding rod 395 is vertically arranged above the rotating gear 392, and the sliding rod 395 is slidably connected to the L-shaped side plate 391. A clamping block 396 is connected to the bottom end of the sliding rod 395, and the clamping block 396 is engaged with the tooth groove on the rotating gear 392. A pull block 397 is connected to the top end of the sliding rod 395, and the pull block 397 is connected to the L-shaped side plate 391 through a spring 398. In this embodiment, the sliding rod 395 is arranged vertically, and the sliding rod 395 can slide up and down on the L-shaped side plate 391. The clamping block 396 is a wedge-shaped clamping block, and the tip of the clamping block 396 faces downward. The spring 398 is in a stretched state in the initial state, and the spring 398 can pull the pull block 397 down, so that the clamping block 396 clamps and fixes the rotating gear 392, so as to achieve the height fixation of the sowing tube 34.

[0024] Specifically, scale lines are also provided on the outer side wall of the sowing tube 34. In this embodiment, by providing scale lines, it is convenient for the staff to accurately adjust and determine the height of the sowing tube 34.

[0025] Specifically, a flattening roller 4 is rotatably connected to the vehicle body 1. In this embodiment, the flattening roller 4 can flatten the soil pile after sowing and bury the seeds during the rotation process.

[0026] Working principle: When in use, pour the seeds into the material box 2, then push the hinge block 37 to slide on the support frame 31, and the hinge block 37 drives the slider 33 to slide on the slide rail 32 through the connecting rod 36, thereby adjusting the distance between two adjacent sowing tubes 34 to meet the row spacing requirements of crop plants. When the distance between two adjacent sowing tubes 34 is adjusted, rotate the rotating handle 382, ​​and the rotating handle 382 drives the threaded shaft 383 to rotate, so that the rubber pad 384 abuts against the support frame 31, thereby fixing the hinge block 37, and at the same time pull the pull block 397 upward to disengage the clamping block 396 from the rotating gear 392, and rotate the knob 394, the knob 394 drives the rotating gear 392 to rotate, and then drives the sowing tube 34 to move up and down through the gear rack meshing structure to achieve the purpose of adjusting the height of the sowing tube 34. Then the vehicle body 1 is controlled to move at a constant speed. During the movement of the vehicle body 1, the seeds in the material box 2 fall into the sowing groove on the ground through the retractable hose 35 and the sowing tube 34, and then the soil is flattened by the flattening roller 4, thereby completing the sowing process.
