[0039] See also Figure 1-4 The present invention is an automatic seeding device for agriculture, comprising a base, a box body 2, a screening component and a quantitative feeding component.

[0040] A moving wheel 3 is installed at the bottom of the base; and a handrail 4 is arranged on one side of the bottom plate 1.

[0041] The box body 2 is installed on the base, and a feed inlet 201 is opened on the top;

[0042] The screening component is arranged in the box 2 and is used for screening agricultural seeds;

[0043] The quantitative feeding assembly is located below the screening assembly; the quantitative feeding assembly includes a limiting roller 9, two sets of limiting blocks 15, a plurality of feeding barrels 8 and a driving member.

[0044] The limiting roller 9 is rotatably mounted in the box body 2 via the rotating shaft 7; a plurality of rows of quantitative grooves 901 are arranged circumferentially on the surface of the limiting roller 9;

[0045] Two groups of limit blocks 15 are symmetrically arranged on both sides of the limit roller 9 and fixedly installed on the inner wall of the box body 2; the side of the limit block 15 close to the limit roller 9 is in contact with the surface of the limit roller 9;

[0046] A plurality of unloading barrels 8 are installed in a row on the base, with one end located below the base and the other end located below the limiting roller 9, and corresponding one to one with the quantitative slots 901 in a row;

[0047] The driving member is used to drive the rotating shaft 7 to rotate.

[0048] It should be noted that

[0049] 1) There are channels at the upper and lower ends between the two groups of limit blocks 15, which are used to make the seeds fall into the quantitative grooves 901 of the limit roller 9 and make the seeds in the quantitative grooves 901 fall into the discharge barrel 8. When the limit roller 9 rotates to a row of quantitative grooves 901 facing the channel, the accumulated seeds above the limit blocks 15 will fall into the quantitative grooves 901.

[0050] When the automatic agricultural sowing device of the present invention is working, agricultural seeds are first added into the box body 2 through the feed port 201, and the seeds fall into the screening component for screening. The seeds that meet the size requirements fall into the quantitative feeding component and wait for sowing; the base is then moved by the moving wheel 3. During the movement, the driving part works and drives the limiting roller 9 to rotate through the rotating shaft 7. When the limiting roller 9 rotates to a row of quantitative grooves 901 facing the channel, the accumulated seeds above the limiting block 15 will fall into the quantitative grooves 901. As the limiting roller 9 continues to rotate, when a row of quantitative grooves 901 faces the feeding barrel 8, the seeds in the quantitative grooves 901 fall into the land to be sown through the feeding barrel 8.

[0051] The agricultural automatic sowing device of the present invention is provided with a screening component to screen the seeds and filter out unqualified seeds, thereby improving the survival rate of sowing; by providing a quantitative feeding component, the driving part works and drives the limiting roller 9 to rotate through the rotating shaft 7. When the limiting roller 9 rotates to a row of quantitative grooves 901 facing the channel, the accumulated seeds above the limiting block 15 will fall into the quantitative groove 901. As the limiting roller 9 continues to rotate, when a row of quantitative grooves 901 faces the feeding barrel 8, the seeds in the quantitative grooves 901 fall into the land to be sown through the feeding barrel 8, thereby realizing quantitative sowing, which is beneficial to controlling the density of crops and subsequent maintenance.

[0052] The specific type of the driving member is not limited, and it only needs to be able to drive the rotating shaft 7 to rotate. For example, a servo motor can be directly provided to connect the rotating shaft 7. Of course, considering the uniformity of the material feeding, in one embodiment of the present invention, the driving member can be a transmission belt 6. Figure 1-4 The driving member includes a transmission belt 6; one end of the transmission belt 6 is connected to the rotating shaft 7 through a pulley, and the other end is connected to the axle of the moving wheel 3 through a pulley. The moving wheel 3 drives the rotating shaft 7 to rotate at the same time when the base is driven forward, so that the moving wheel 3 can move a similar distance each time the feeding barrel 8 discharges the material, and uniform sowing can be achieved.

[0053] It is necessary to add that

[0054] 2) The selection of the pulley, or the setting of the transmission ratio, can be selected according to the specific sowing conditions and can control the distance between adjacent sowing positions.

[0055] 3) In some other embodiments, the driving member can also be implemented in the form of gear transmission, and mutually meshing gears are set on the wheel shaft and the rotating shaft 7.

[0056] 4) In order to prevent the seeds from piling up on the limiting block 15 and causing the seeds to fall poorly, in the specific implementation, a slope that facilitates unloading can be set above the limiting block 15.

[0057] In the present invention, the specific type of the screening component is not limited, as long as it can screen the seed size. For example, a screen plate can be directly set at the feed inlet 201. Considering that the seed size should be neither too large nor too small, in one embodiment of the present invention, please combine Figure 2-4 The screening component may include a screening frame 10 , a first screen plate 11 , a second screen plate 12 , a first discharge channel 13 and a second discharge channel 14 .

[0058] The screening frame 10 is located in the box body 2; the first sieve plate 11 is installed obliquely in the screening frame 10; the second sieve plate 12 is located below the first sieve plate 11, and the inclination direction is opposite to the inclination direction of the first sieve plate 11; one end of the first discharge channel 13 is connected to the screening frame 10 on the lower end side of the first sieve plate 11, and the other end slides through to the outside of the box body 2; one end of the second discharge channel 14 is connected to the screening frame 10 on the lower end side of the second sieve plate 12, and the other end is located in the box body 2; wherein, the sieve holes of the first sieve plate 11 are larger than the sieve holes of the second sieve plate 12.

[0059] In the present invention, the first sieve plate 11 is used to screen out seeds that are too large in size, and under the action of the first discharge channel 13, the screened seeds can be discharged out of the box body 2; the second sieve plate 12 is used to screen out seeds that are too small in size, and the screened seeds fall to the bottom of the screening frame 10 for collection, and under the action of the second discharge channel 14, the seeds that meet the requirements can be discharged into the box body 2, and then fall on the limit block 15 for accumulation.

[0060] It is necessary to add that

[0061] 5) In the present invention, a collecting bag or a collecting box can be provided outside the first discharging channel 13 to collect the screened seeds to prevent them from falling into the soil. The collecting bag or the collecting box can be placed on the base; of course, an openable door can be provided on one side of the box body 2 to facilitate internal inspection and removal of seeds inside the screening frame 10.

[0062] To improve the screening effect, please combine Figure 1-4 In some embodiments of the present invention, sliders 203 can be connected to both sides of the screening frame 10 through connecting rods; the sliders 203 are slidably arranged in the preset slide grooves 202 on the inner wall of the box body 2; and a hydraulic cylinder is arranged between the outer wall of the screening frame 10 and the inner wall of the box body 2.

[0063] The operation of the hydraulic cylinder can drive the screening frame 10 to shake left and right along the slide groove 202, and the screening efficiency of the screen plate can be improved by shaking.

[0064] To improve practicality, please combine Figure 1-3 In one embodiment of the present invention, a soil covering plate 5 is provided at the bottom of the bottom plate 1 on one side of the handrail 4. During the movement of the base, the soil covering plate 5 at the tail can cover the seed pit after sowing.
