Sorghum smut is the ear of sorghum head smut caused by Sphacelotheca sorghi, belonging to the fungi of Basidiomycotina, that is, the beneficial fungus of sorghum head smut, which is a kind of fungi. The planting of sorghum smut in China is mainly distributed in Jilin area.

Specific embodiments

[0059] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0060] As Figures 1-8Specific embodiment of a self-propelled sorghum smut seeding device with intermittent material covering function of the present utility model shown in the figure, including a frame 1, a traveling mechanism 2, a ditching mechanism 3, a seed discharging mechanism 4, an intermittent discharging mechanism 5, a soil covering mechanism 6 and a pressing mechanism 7 which are sequentially installed on the frame 1 from front to back. Among them, the intermittent discharging mechanism 5 includes a discharging support 51 installed on the frame 1, a storage and discharging assembly 52, a discharging cylinder 53 and an intermittent blocking assembly 54. The storage and discharging assembly 52 is installed on the discharging support 51, the discharging cylinder 53 is installed at the lower end of the storage and discharging assembly 52, the discharging cylinder 53 is communicated with the cavity of the storage and discharging assembly 52, the intermittent blocking assembly 54 is installed on the frame 1, and the intermittent blocking assembly 54 is correspondingly arranged at the discharging port of the discharging cylinder 53 to control the intermittent discharge of the bacterial soil in the discharging cylinder 53.

[0061] This embodiment improves the traditional seeder. A storage and discharging assembly 52 and a discharging cylinder 53 for storing and discharging the discharged bacterial soil are arranged on the frame 1, and an intermittent blocking assembly 54 is arranged. The intermittent blocking assembly 54 is correspondingly arranged with the discharging port of the discharging cylinder 53 to control the intermittent discharge of the bacterial soil in the discharging cylinder 53. The structure is simple and reliable, which solves the problem that in the prior art, the bacterial soil needs to be manually put in, and a relatively automated seeder cannot be used to sow sorghum smut, and makes the sorghum smut seeding have the advantages of high efficiency, uniform plant spacing and low cost.

[0062] As Figures 4 to 6 shown, in this embodiment, the intermittent blocking assembly 54 includes a vertical frame 541 fixedly installed on the lower end surface of the frame 1, a hollow mounting plate 543 fixedly installed at the discharging port of the discharging cylinder 53, and a first push-type electromagnet 542. The fixed end of the first push-type electromagnet 542 is fixedly installed on the vertical frame 541, and the telescopic end faces the discharging port of the discharging cylinder 53. A first push plate 544 is fixedly arranged with the telescopic end of the first push-type electromagnet 542 and is movably connected to the hollow mounting plate 543 through a first connecting component 547. A second push plate 545 is movably connected to the hollow mounting plate 543 through a second connecting component 548. The first push plate 544 and the second push plate 545 are connected in cooperation through a gear set 546. When the first push-type electromagnet 542 is powered on, the first push plate 544 and the second push plate 545 open relatively, corresponding to the discharging action of the discharging cylinder 53. When the first push-type electromagnet 542 is powered off, the first push plate 544 and the second push plate 545 close to block the discharging of the discharging cylinder 53.

[0063] As an implementation manner, the first connection component 547 in this embodiment includes at least one first connecting rod 5471 and a sliding groove 5472 provided on the hollow mounting plate 543. One end of the first connecting rod 5471 is rotatably mounted on the hollow connecting plate, and the other end is rotatably mounted on the first push plate 544. The second connection component 548 includes at least one second connecting rod 5481. One end of the second connecting rod 5481 is rotatably mounted on the hollow mounting plate 543, and the other end is rotatably mounted on the second push plate 545. Both the first push plate 544 and the second push plate 545 are slidably arranged in the sliding groove 5472.

[0064] It should be further noted that the gear set 546 in this embodiment includes an opening and closing driving gear 5461 mounted on the first connecting rod 5471 and an opening and closing driven gear 5462 mounted on the second connecting rod 5481; the opening and closing driving gear 5461 and the opening and closing driven gear 5462 are externally meshed and connected.

[0065] To achieve automatic control, the seeder in this embodiment is also provided with a PLC control module 10. During use, the PLC control module 10 is used to control the on and off of the first thrust electromagnet 542, so as to accurately adjust the opening and closing of the first push plate 544 and the second push plate 545. The first push plate 544 and the second push plate 545 are used to block or open the discharge port of the discharge cylinder 53. When the first push plate 544 and the second push plate 545 are in the open state, the bacterial soil in the discharge cylinder 53 is discharged. When the first push plate 544 and the second push plate 545 are in the closed state, the bacterial soil in the discharge cylinder 53 cannot be discharged. That is, when the discharge port of the discharge cylinder 53 is located above the seeds, the first thrust electromagnet is energized. After the first thrust electromagnet is energized, it drives the first push plate 544 to contract towards its fixed end. The first push plate 544 moves towards the first thrust electromagnet, and the opening and closing driving gear 5461 rotates to drive the opening and closing driven gear 5462 to rotate, so as to realize the mutual opening of the first push plate 544 and the second push plate 545 and the discharge of the bacterial soil. After discharging a certain amount, the first thrust electromagnet is powered off. Driven by its own elastic deformation, the first thrust electromagnet drives the first push plate 544 to move towards the second push plate 545. When the first push plate 544 and the second push plate 545 are completely closed, the blocking of the bacterial soil is realized, that is, the intermittent discharge of the bacterial soil is realized.

[0066] Such as Figure 7As shown, the storage and discharge assembly 52 in this embodiment includes a storage bin 521 with a lower opening, a discharge motor 522 and a stirring unit 523. The storage bin 521 with a lower opening is fixedly mounted on the discharge bracket 51, the discharge motor 522 is mounted on the discharge bracket 51, the stirring unit 523 is rotatably mounted in the storage bin 521, and is connected to the output shaft of the discharge motor 522 through a third transmission assembly. The discharge barrel 53 is connected to the storage bin 521 pipeline. The storage bin 521 in this embodiment is provided with a stirring unit 523, which is driven to rotate by the discharge motor 522 and the third transmission assembly, and can effectively avoid the arching phenomenon of the fungus soil, thereby allowing the fungus soil to be discharged in an orderly manner, thereby improving the working efficiency. It should be understood that any stirring unit that can be purchased on the market or that can be thought of by those skilled in the art can be applied to this embodiment, and the specific structure of the stirring unit will not be described in detail here.

[0067] As a preferred embodiment, the storage bin 521 is made of transparent material, which can observe the amount of bacterial soil in the storage bin 521 in real time. When the bacterial soil is too little, the operator is reminded to replenish it in time.

[0068] The sowing device of this embodiment further includes a quantitative component 8 for controlling the quantitative discharging of the discharging cylinder 53, see Figure 4 and Figure 7 The quantitative assembly 8 includes a second thrust electromagnet 81 mounted on the vertical frame 541, an arc-shaped baffle 82 mounted on the telescopic end of the second thrust electromagnet 81, and a quantitative transverse groove 83 provided on the discharge barrel 53 for cooperating with the arc-shaped baffle 82. When in use, the arc-shaped baffle 82 is horizontally inserted into the quantitative transverse groove 83. The position of the quantitative transverse groove 83 on the discharge barrel 53 is set according to the usage in the specific usage scenario. When the second thrust electromagnet 81 is in the de-energized state, the arc-shaped baffle 82 is completely set in the quantitative transverse groove 83, dividing the inner cavity of the discharge barrel 53 into upper and lower ends. The fungus soil in the lower end of the discharge barrel 53 is the coverage amount of the seeds at one time.

[0069] like Figure 8As shown, the furrowing mechanism 3 in this embodiment includes a furrowing support 31, a flat furrowing plow 32, and two retaining plates 33. The furrowing support 31 is fixed to the frame 1 via at least one U-shaped connector 34. The flat furrowing plow 32 is disposed at the lower end of the furrowing support 31 and is used to create a sowing furrow in the soil. Two retaining plates 33 are disposed on either side of the flat furrowing plow 32. The flat furrowing plow 32 and the two retaining plates 33 enclose a cavity, and the sowing end of the seeding mechanism 4 is disposed within the cavity. The furrowing plow in this embodiment uses a flat furrowing plow 32 with a flat bottom surface. The flat bottom surface of the furrowing plow can create a relatively flat seed furrow, which facilitates improving the seeding concentration of the seed meter and the accuracy of the soil covering the seeds, thereby ensuring sowing quality. At the same time, the furrowing support 31 is adjustably mounted to the frame 1 using a U-shaped connector 34, making the sowing depth adjustable. This allows for sowing of sorghum and black rice with different sowing requirements, thus providing wide applicability.

[0070] The walking mechanism 2 in this embodiment includes a walking wheel 21, a first rotating shaft 22, a drive motor 23 and a speed sensor, wherein the walking wheel 21 is rotatably mounted at the front end of the frame 1; the first rotating shaft 22 is mounted in the middle of the walking wheel 21 to drive the walking wheel 21 to rotate; the drive motor 23 is mounted on the frame 1; the speed sensor is mounted on the walking wheel 21 to detect the walking speed of the walking wheel 21 in real time; the first rotating shaft 22 and the output shaft of the drive motor 23 are connected through a first transmission assembly 24.

[0071] The seeding mechanism 4 includes a seeding support frame 41 and a seeding assembly 42. The seeding support frame 41 is fixedly installed in the middle position of the frame 1 through a support rod; the seeding assembly 42 is installed on the seeding support frame 41, and is used to sow seeds into the seeding furrows opened by the corresponding furrowing mechanism 3; the seeding assembly 42 includes a seed storage bin, a seeding disk installed below the seed storage bin, a second rotating shaft that drives the seeding disk to rotate, and a seed guide tube arranged below the seeding disk; the second rotating shaft is connected to the first rotating shaft 22 through a second transmission assembly 43.

[0072] Specifically, the first transmission assembly 24 in this embodiment includes a first driving gear 241 coaxially arranged with the output shaft of the drive motor 23, a first driven gear 242 coaxially arranged with one end of the first rotating shaft 22, and the first driven gear 242 and the first driving gear 241 are connected by a chain transmission. The second transmission assembly 43 includes a second driving gear 431 coaxially arranged with the other end of the first rotating shaft 22, and a second driven gear 432 coaxially arranged with the second rotating shaft, and the second driven gear 432 and the second driving gear 431 are connected by a chain transmission.

[0073] The traveling mechanism 2 and the seeding mechanism 4 in this embodiment are driven by the same motor, which reduces the cost on the one hand and can simultaneously control the rotation of the traveling wheel 21 and the seeding disc on the other hand, facilitating unified control.

[0074] The compaction mechanism 7 in this embodiment includes a compaction frame rotatably mounted on the frame 1 and compaction wheels rotatably mounted on the compaction frame. Of course, the compaction mechanism 7 in this embodiment can also adopt compaction mechanisms 7 with other structures on the market, as long as it can flatten the bottom surface after covering the soil. There is no absolute limitation on the compaction mechanism 7 here. At the same time, it should be understood that the soil covering mechanism 6 in this embodiment adopts a soil covering mechanism 6 that can be purchased on the market or can be easily thought of by those skilled in the art. The specific structure of the soil covering mechanism 6 will not be elaborated in detail here.

[0075] It should be understood that the seeding device in this embodiment should also include a handrail 9 for the operator to hold. During use, the operator places both hands on the handrail 9 to control the stability and direction of the seeding device.

[0076] The working process of the seeding device in this embodiment is as follows and is carried out in sequence:

[0077] Ditching stage: After all preparations are made, each device is powered on. The driving motor 23 drives the traveling wheels 21 through the first transmission assembly 24, driving the entire frame 1 to travel. The plow of the ditching mechanism 3 digs out a seed furrow with a flat bottom surface as shown in the appendix. Figure 2 as shown.

[0078] Seeding stage: The seed metering assembly 42 adopts a cell wheel type and is driven in a driving relationship with the traveling wheels 21 through the second transmission assembly 43 to drive the seed metering assembly 42 to seed.

[0079] Intermittent discharging of bacterial soil stage: The discharging motor 522 drives the stirring unit 523 to rotate, discharging the bacterial soil in the storage bin 521 into the guide tube. At this time, the first push electromagnet 542 is de-energized, and the second push electromagnet 81 is energized. When the guide tube is full of discharged material, the second push electromagnet 81 is de-energized, and the first push electromagnet 542 is energized, quantitatively discharging the bacterial soil at the lower part of the guide tube. By controlling the energization and de-energization of the two push electromagnets, the quantitative and positioned discharging of the bacterial soil is realized. It should be further noted that, in order to achieve full automation as much as possible, an optoelectronic sensor can be installed at the end of the guide pipe. When seeds are detected, the information is transmitted to the PLC control module 10 control system, and then the PLC control module 10 controls the discharging motor 522 to rotate, and the bacterial soil falls into the guide pipe to ensure the smooth progress of discharging. In this embodiment, a quantitative assembly 8 can be used to quantitatively discharge the bacterial soil, or the PLC control module 10 can calculate the discharging time and the diameter of the guide pipe for quantification. Specifically, the storage time is determined by calculating the time required for the discharging assembly to discharge the required quantitative bacterial soil, and the final fertilizing time is calculated based on the time from when the seeds pass through the optoelectronic sensor of the seed guiding pipe to reaching the ground and the distance between the guide pipe and the seed guiding pipe orifice, so as to achieve intermittent quantitative bacterial soil and precisely cover the seeds as shown in the appendix. Figure 4As shown. In the final discharging stage, the first push electromagnet 542 drives the first push plate 544 and the second push plate 545, and drives the first push plate 544 and the second push plate 545 to open and close through the principle of the scale bar of the gear set 546, so as to achieve the effect of rapid discharging, which can greatly increase the formation of the material pile.

[0080] Soil covering stage: When the ditch opening stage, the seeding stage, and the intermittent bacterial soil discharging stage are completed, the soil covering component evenly pushes the soil on both sides of the seeding ditch onto the seeding ditch.

[0081] Soil compaction stage: Reasonably compact the soil evenly covered in the soil covering stage.

[0082] Stopping stage: When the speed sensor detects that the stopping speed of the whole machine is 0, the PLC control module 10 controls the discharging motor 522 to stop, so as to stop discharging to avoid waste of bacterial soil.

[0083] The seeding mechanism of this embodiment realizes the mechanized seeding of sorghum smut through each mechanism. The seed spacing is more reasonable, the seeding depth is uniform, and the covering amount of bacterial soil is accurate, effectively improving the seeding of sorghum smut and realizing scientific planting.

[0084] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or variations derived from the spirit of the present invention are still within the protection scope of the present invention.
