[0002] The nutritional value of carrots has been increasingly valued by people. The carotene in carrots is the main source of vitamin A. Therefore, more and more farmers choose to grow carrots. Carrots are usually sown in autumn. According to the development of modern science and technology, most of the sowing methods of carrots adopt mechanized sowing, and air-suction seeders are recognized by most people. Air-suction seeders can achieve single-seed sowing, and precision sowing can reduce seed consumption, reduce seed costs, and improve sowing precision. After actual field testing, the qualified rate of sowing spacing can reach 87%-94%, which can achieve high-speed sowing. For this reason, a new type of air-suction carrot sowing device is proposed.

[0003] Most of the existing air-suction carrot sowing devices are welded according to the distance of the sowing furrows. After welding, the sowing furrow distance has great limitations and different sowing furrow distances cannot be sown. In addition, when sowing, the existing air-suction carrot sowing device has uneven heights of the sowing furrows, and the sowing device will vibrate during the sowing process, affecting the sowing effect.

[0016] Technical effects and advantages of the utility model:

[0017] 1. The utility model is provided with a furrow distance adjustment device, which is conducive to adjusting the sowing distance according to the furrow distance. A threaded rod is inserted into the connecting frame at the upper end of one side of the connecting frame. Therefore, when the connecting frame moves, the steel gasket can be squeezed by disassembling and installing the threaded rotating cylinder to achieve the effect of fixing the connecting frame. Because the lower end of the connecting frame wraps one side of the connecting frame through the C-shaped limit block, the movement and limiting effect of the connecting frame is achieved. When the sowing distance needs to be adjusted, the threaded rotating cylinder is loosened, the connecting frame is translated, and the air suction seeder and the seeder frame are driven to move, thereby achieving the adjustment effect. When the adjustment is completed, the threaded rotating cylinder is tightened to squeeze between the steel gasket and the connecting frame to achieve the effect of fixing the connecting frame.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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 the field of carrot sowing without creative work are within the scope of protection of the utility model.

[0025] like Figure 1 and 2As shown, the utility model provides an air-suction carrot seeding device, including a connecting frame 1; two supporting wheels 4 are fixedly provided at the lower end of the connecting frame 1, and a seeder frame 5 is movably provided on the other side of two second movable rods 32 and two first movable rods 31, a plow 6 is fixedly provided at the lower end of the seeder frame 5, an air-suction seeder 7 is fixedly provided on the inner side of the seeder frame 5, two roller connecting rods 11 are movably provided on one side of the seeder frame 5 through a connecting piece, a rolling wheel 9 is movably provided between the roller connecting rods 11, one side of the rolling wheel 9 is transmission-connected to the input end of the air-suction seeder 7 through a crawler transmission member 10, a spring column 8 is provided between the two roller connecting rods 11, and the top of the spring column 8 extends out of the top of the seeder frame 5.

[0026] In order to adjust the sowing distance according to the furrow distance, a furrow distance adjusting device 2 capable of adjusting according to the furrow distance is provided on one side of the connecting frame 1, and is used to adjust the sowing distance according to the furrow distance;

[0027] like Figure 3 As shown, the groove spacing adjustment device 2 includes a C-shaped limit block 21, which is movably arranged on the outer surface of one side of the connecting frame 1, a connecting frame 22 is fixedly arranged on one side of the C-shaped limit block 21, a threaded rod 24 is fixedly arranged on one side of the upper end of the connecting frame 22, a bracket 23 is fixedly arranged on the upper end of one side of the connecting frame 1, the threaded rod 24 is located in the groove of the bracket 23, a steel gasket 25 is movably arranged on the outer surface of the threaded rod 24, a threaded rotating cylinder 26 is threadedly connected to the outer surface of the threaded rod 24, the steel gasket 25 and the threaded rotating cylinder 26 are located on one side of the bracket 23, and the threaded rod 24 is inserted into the bracket 23 at the upper end of one side of the connecting frame 1. When the connecting frame 22 moves, by removing and installing the threaded rotating cylinder 26, the steel gasket 25 can be squeezed to achieve the effect of fixing the connecting frame 22. Since the lower end of the connecting frame 22 wraps one side of the connecting frame 1 through the C-shaped limit block 21, the movement and limiting effect of the connecting frame 22 is achieved. When the sowing distance needs to be adjusted, the threaded rotating cylinder 26 is loosened, the connecting frame 22 is translated, and the air suction seeder 7 and the seeder frame 5 are driven to move, thereby achieving the adjustment effect. When the adjustment is completed, the threaded rotating cylinder 26 is tightened to squeeze the steel gasket 25 and the bracket 23, thereby achieving the effect of fixing the connecting frame 22.

[0028] Further, in order to reduce the vibration frequency during sowing and improve the sowing efficiency, a spring damper 3 capable of reducing the vibration frequency during sowing is provided on one side of the furrow spacing adjustment device 2 (the spring damper 3 is an existing spring shock absorber, model KS-290);

[0029] like Figure 4As shown, the spring damper 3 includes two first movable rods 31 and two second movable rods 32, and the two first movable rods 31 and the two second movable rods 32 are movably arranged on the inner side of the connecting frame 22 through connecting pieces respectively. A first hinge 33 is movably arranged between the two first movable rods 31, and a second hinge 34 is movably arranged between the two second movable rods 32. A second limiting plate 38 is fixedly arranged at the movable end of the first hinge 33, and a first limiting plate 35 is fixedly arranged at the movable end of the second hinge 34. A damper 36 is fixedly arranged between the first limiting plate 35 and the second limiting plate 38, and a strong spring 37 is movably arranged on the outer surface of the damper 36. The parallelogram formed by the two first movable rods 31 and the two second movable rods 32 realizes the mobility of the seed drill frame 5. Through the damper 36 and the strong spring 37 connected between the first hinge 33 and the second hinge 34, when the air-suction seed drill 7 and the seed drill frame 5 are subjected to force reduction and when sowing and moving, the damper 36 and the strong spring 37 can slow down the vibration frequency, so that the sowing efficiency is better.

[0030] The working principle is as follows: when the utility model is in use, the connecting frame 1 is fixed on the mobile device, and the sowing distance is adjusted by the furrow distance adjusting device 2. When the seeder frame 5 and the air-suction seeder 7 are lowered, the plow 6 is inserted into the soil. When the connecting frame 1 is pulled by the mobile device for sowing, the rolling wheel 9 rotates due to the friction of the ground, and the turntable in the air-suction seeder 7 is driven to rotate by the crawler transmission part 10, thereby achieving uniform sowing of particles. During the sowing process, it is inevitable that the utility model will shake and vibrate due to the uneven ground. Through the spring damper 3, the air-suction seeder 7 can be moved smoothly, thereby reducing the shaking frequency and improving the sowing efficiency.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
