[0054] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0055] Please also see Figure 1-Figure 7 The utility model provides some preferred embodiments of a coix seeding machine.

[0056] like Figure 1-Figure 3 As shown, the Job's tears planter includes:

[0057] Car body 10;

[0058] A trenching mechanism 20, provided on the vehicle body 10, and used for forming trenches on the soil;

[0059] A sowing mechanism 30, disposed on the vehicle body 10, and used for sowing coix seeds into the open furrow;

[0060] A soil covering mechanism 40 is elastically connected to the vehicle body 10;

[0061] The soil covering mechanism 40 is used to push the soil on both sides of the trench to fill the trench and compact the filled soil.

[0062] Specifically, before sowing the coix seeds, the soil can be plowed first to make the soil looser, and then the furrowing mechanism 20 can more easily realize furrowing when sowing with the coix seeding machine of the present application. The furrowing mechanism 20 separates the soil and forms a furrow from the middle, so that there is more soil on both sides of the furrow. The sowing mechanism 30 puts the coix seeds into the furrow. The covering mechanism 40 pushes the soil on both sides of the furrow into the furrow to fill the furrow and compact it. Since the covering mechanism 40 is elastically connected to the vehicle body 10, when compacting the soil, if the soil is hard or the road surface is bumpy, the harder soil is compacted by elastic force, and the covering mechanism 40 is adaptively adjusted to adapt to the bumpy road surface, thereby improving the covering and compacting effect.

[0063] In a preferred embodiment of the present invention, please also refer to Figure 1-Figure 2 , the vehicle body 10 comprises:

[0064] Base frame 11;

[0065] Two steering wheels 12, rotatably connected to the base frame 11;

[0066] Two driving wheels 13, rotatably connected to the base frame 11;

[0067] A second driving member 14 is disposed on the base frame 11 and is used to drive the steering wheel 12 to rotate;

[0068] The third driving member 15 is disposed on the base frame 11 and is used to drive the driving wheel 13 to rotate.

[0069] Specifically, the wheels of the vehicle body 10 are divided into steering wheels 12 and driving wheels 13. The steering wheels 12 rotate in the horizontal plane to adjust the driving direction of the vehicle body 10; the driving wheels 13 rotate in the vertical plane to drive the vehicle body 10 to move. Of course, when the vehicle body 10 moves, the steering wheels 12 will also rotate in the vertical plane. The number of steering wheels 12 and the number of driving wheels 13 can be configured as needed, for example, two steering wheels 12 are configured and two driving wheels 13 are configured.

[0070] In a preferred embodiment of the utility model, the coix seeding machine further comprises a controller, and the seeding mechanism 30 is electrically connected to the controller. In addition, the second driving member 14 and the third driving member 15 are electrically connected to the controller.

[0071] Specifically, the controller supplies power to the sowing mechanism 30 , the second driving member 14 , and the third driving member 15 , and controls the sowing mechanism 30 , the second driving member 14 , and the third driving member 15 .

[0072] In a preferred embodiment of the present invention, please also refer to Figure 3-Figure 4 , the soil covering mechanism 40 comprises:

[0073] An elastic component 41 connected to the vehicle body 10;

[0074] A first soil covering plate 42, a pressure roller 43 and a second soil covering plate 44 connected in sequence;

[0075] Wherein, the first soil cover plate 42 and the second soil cover plate 44 are both connected to the elastic component 41;

[0076] The connecting line between the pressing roller 43 and the trenching mechanism 20 is parallel to the traveling direction of the vehicle body 10;

[0077] The first covering plate 42 and the second covering plate 44 are inclined toward the trenching mechanism 20 from the inner end to the outer end.

[0078] Specifically, the elastic component 41 realizes the elastic connection between the soil covering mechanism 40 and the vehicle body 10. The elastic component 41 provides the pressure roller 43 with an elastic force to move downward, so that on the basis of the gravity of the pressure roller 43 itself, combined with the elastic force of the elastic component 41, pressure is applied to the soil, which is conducive to improving the compaction effect. The first soil covering plate 42 and the second soil covering plate 44 correspond to the positions on both sides of the trench, respectively, and the soil on both sides of the trench is gathered and spread into the trench. The lower end of the pressure roller 43 is lower than the lower end of the first soil covering plate 42, and the lower end of the pressure roller 43 is lower than the lower end of the second soil covering plate 44. The pressure roller 43 is rotatably connected to the first soil covering plate 42 and the second soil covering plate 44. Since the pressure roller 43 can rotate, it is easier for the pressure roller 43 to roll forward with the vehicle body 10 during the soil compaction process. The first covering plate 42 and the second covering plate 44 are tilted to form an eight-shaped shape, the inner end of the first covering plate 42 is rotatably connected to the pressure roller 43, the inner end of the second covering plate 44 is rotatably connected to the pressure roller 43, the outer end of the first covering plate 42 faces the outside of the vehicle body 10, and the outer end of the second covering plate 44 faces the outside of the vehicle body 10. The outer end of the first covering plate 42 and the outer end of the second covering plate 44 are closer to the trenching mechanism 20, which is conducive to gathering the soil on both sides of the trench to the middle to fill the trench.

[0079] In a preferred embodiment of the present invention, a connecting plate is provided on the first covering plate 42 and the second covering plate 44, and the connecting plate is used to connect the pressure roller 43. The elastic component 41 includes:

[0080] An elastic member, with two ends respectively connected to the vehicle body 10 and the connecting plate;

[0081] The telescopic rod has two ends connected to the vehicle body 10 and the connecting plate respectively.

[0082] Specifically, the telescopic rod is vertically arranged, and the telescopic rod plays a guiding role. The pressure roller 43 moves downward under the elastic force provided by the elastic member.

[0083] In a preferred embodiment of the present invention, please also refer to Figure 3-Figure 4The soil covering mechanism 40 further comprises:

[0084] Telescopic assembly 45;

[0085] The elastic component 41 is connected to the vehicle body 10 via the telescopic component 45 .

[0086] Specifically, the telescopic component 45 can be telescopic. When soil covering work is required, the telescopic component 45 can be extended, the first soil covering plate 42, the pressure roller 43 and the second soil covering plate 44 can be pressed down to contact the soil, and the elastic force applied by the elastic component 41 can be adjusted; when soil covering work is not required, the telescopic component 45 can be shortened, the first soil covering plate 42, the pressure roller 43 and the second soil covering plate 44 can be lifted up to separate from the soil.

[0087] In a preferred embodiment of the present invention, please also refer to Figure 5-Figure 7 , the sowing mechanism 30 comprises:

[0088] A seed bin 31 is provided on the vehicle body 10, and an outlet 312 is provided at the lower end of the seed bin 31;

[0089] A bracket 32, disposed on the vehicle body 10;

[0090] A baffle plate 33 is disposed on the bracket 32, and a notch 331 is formed on the baffle plate 33;

[0091] The groove wheel 34 is rotatably connected to the bracket 32 ​​and abuts against the upper surface of the baffle 33. The groove wheel 34 is provided with a plurality of temporary storage holes 341 and a plurality of connecting grooves 342. The temporary storage holes 341 rotate to the bottom of the outlet 312 to temporarily store the coix seeds, and continue to rotate to the top of the notch 331 to release the coix seeds;

[0092] A rotating member 35 is rotatably connected to the bracket 32, and an eccentric column 351 is provided on the rotating member 35, and the eccentric column 351 is inserted into the communicating groove 342;

[0093] The first driving member 36 is disposed on the bracket 32 ​​and is used to drive the rotating member 35 to rotate.

[0094] Specifically, the seed bin 31 is used to store coix seeds. An entrance is provided at the upper end of the seed bin 31, and a cover plate 311 is provided at the entrance. An exit 312 is provided at the lower end of the seed bin 31, and the exit 312 allows the coix seeds to leak out. The bracket 32 ​​is provided on the vehicle body 10, and a rotating shaft 321 is provided on the bracket 32. The groove wheel 34 rotates relative to the rotating shaft 321. As the groove wheel 34 rotates, the temporary storage holes 341 on the groove wheel 34 pass under the exit 312 in sequence, thereby temporarily storing the coix seeds falling from the exit 312 in sequence. Since there is a baffle 33 under the groove wheel 34, the coix seeds in the temporary storage hole 341 are blocked by the baffle 33 to achieve temporary storage of the coix seeds. There is a notch 331 on the baffle 33. When the temporary storage hole 341 rotates to above the notch 331, the coix seeds in the temporary storage hole 341 fall down without being blocked and enter the open ditch below. The gap 331 is located between the soil covering mechanism 40 and the furrowing mechanism 20. After the coix seeds fall into the furrow from the gap 331, the soil covering mechanism 40 will cover and compact the soil. The position of the gap 331 is staggered with the position of the outlet 312. The coix seeds falling from the outlet 312 enter the temporary storage hole 341. The coix seeds need to rotate with the temporary storage hole 341 until they reach the gap 331 and fall into the furrow.

[0095] The first driving member 36 is used to drive the rotating member 35 to rotate. The rotating member 35 is provided with an eccentric column 351, which deviates from the rotation center of the rotating member 35. When the rotating member 35 rotates, the eccentric column 351 forms a circular moving track. Since the eccentric column 351 is inserted into the connecting groove 342, as the eccentric column 351 rotates, the groove wheel 34 is driven to rotate intermittently, so that intermittent sowing can be achieved. By utilizing the intermittent nature of the groove wheel 34 and cooperating with the continuous rotation of the first driving member 36, intermittent sowing can be achieved. The rotating member 35 cooperating with the groove wheel 34 rotates continuously with the first driving member 36. Due to the intermittent characteristics of the groove wheel 34, the groove wheel 34 will be caused to rotate intermittently, and the temporary storage hole 341 above the groove wheel 34 and the gap 331 below are intermittently overlapped to achieve intermittent sowing. On the basis of the groove wheel 34, a sowing mode of first sorting and then sowing is used to solve the problems of stuck seeds and leaking seeds in the existing sowing machine. When the eccentric column 351 comes out of one connecting groove 342 and enters another connecting groove 342 , it does not drive the groove wheel 34 to rotate.

[0096] In a preferred embodiment of the present invention, please also refer to Figure 6-Figure 7 The bracket 32 ​​is provided with a seed dropping tube 37 , and the seed dropping tube 37 is located at a corresponding position of the notch 331 .

[0097] Specifically, in order to guide the coix seeds falling from the gap 331, a seed drop tube 37 is provided on the bracket 32 ​​so that the coix seeds fall accurately into the ditch. The cross section of the seed drop tube 37 can be arc-shaped, so that the temporary storage hole 341 can correspond to the seed drop tube 37 during a period of rotation, and the coix seeds in the temporary storage hole 341 have sufficient release time.

[0098] In a preferred embodiment of the present invention, please also refer to Figure 6-Figure 7 There are four communicating grooves 342, and the four communicating grooves 342 are connected at the center of the groove wheel 34; there are four temporary storage holes 341, and they are located between two adjacent communicating grooves 342; with the center of the groove wheel 34 as the angle tip, the angle between the rotating member 35 and the outlet 312 is 45° or 135°.

[0099] Specifically, the number of the connecting grooves 342 is the same as the number of the temporary storage holes 341. The specific number can be configured as needed. For example, the connecting grooves 342 are configured as four, and the temporary storage holes 341 are also configured as four. The temporary storage hole 341 is located between two adjacent connecting grooves 342. The rotating member 35 forms a first connecting line with the center of the groove wheel 34, and the outlet 312 forms a second connecting line with the center of the groove wheel 34. The angle between the first connecting line and the second connecting line is 45° or 135°. Since the eccentric column 351 does not rotate when it moves between two adjacent connecting grooves 342, there is enough time for the coix seeds at the outlet 312 to fall into the temporary storage hole 341. When the angle is 45° or 135°, the temporary storage hole 341 stops below the outlet 312. The notch 331 forms a third connecting line with the center of the groove wheel 34. The angle between the first connecting line and the third connecting line is 90° or 180°. The temporary storage hole 341 stops above the notch 331.

[0100] In a preferred embodiment of the present invention, please also refer to Figure 1 and Figure 3 The height of the trenching mechanism 20 is adjustable.

[0101] Specifically, the height of the furrowing mechanism 20 is adjustable, so the depth of the furrow formed by the furrowing mechanism 20 can be adjusted, and the depth of the coix seed sowing can be adjusted. The vehicle body 10 is provided with a first locking hole 111, and the furrowing mechanism 20 includes: a vertical rod 21 and a double-sided shovel 22 connected to each other, and a plurality of second locking holes 211 are provided on the vertical rod 21. By adjusting the second locking holes 211 corresponding to the first locking holes 111, the height of the double-sided shovel 22 can be adjusted to change the depth of the furrow.

[0102] In a preferred embodiment of the present invention, please also refer to Figure 1-Figure 3 , the coix seeding machine also includes:

[0103] The watering and fertilizing mechanism 50 is disposed on the vehicle body 10 and is used for watering and fertilizing the soil.

[0104] Specifically, since the germination and growth of coix seeds require more water and fertilizer, watering and fertilization are required after sowing and covering with soil. The fertilizer can be liquid fertilizer, which can be mixed with water. The watering and fertilization mechanism 50 is electrically connected to the controller.

[0105] In a preferred embodiment of the present invention, please also refer to Figure 1-Figure 3 The watering and fertilizing mechanism 50 comprises:

[0106] A box body 51 is provided on the vehicle body 10;

[0107] a check valve, connected to the box body 51;

[0108] The sprayer 52 is communicated with the check valve.

[0109] Specifically, in order to prevent the water in the box 51 from leaking out, a check valve is provided at the liquid outlet of the box 51. The sprayer 52 is conducive to uniform watering and fertilization. The sprayer 52 includes an output pump 521 and a plurality of nozzles 522, and the output pump 521 can be a gear pump.
