DETAILED DESCRIPTION
[0029] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the following embodiments will be described in detail in combination with the drawings. It should be noted that the descriptions of these embodiments are used to help understand the present application, but do not constitute a limitation of the present application.
[0030] The agricultural soil turning and sowing synchronous device in the present embodiment is used for sowing predetermined seeds on a predetermined ground. Specifically, the agricultural soil turning and sowing synchronous device is in the form of a vehicle body and moves along a straight traveling direction D on the predetermined ground.
[0031] As shown in Figure 1 , the agricultural soil turning and sowing synchronous device 100 comprises a device base 10, and a drive assembly 20, a soil turning assembly 30, a sowing assembly 40, a watering assembly 50, and a soil filling assembly, all of which are arranged on the device base 10.
[0032] As shown in Figure 2 , the device base 10 is in the form of a plate rack structure, the bottom of the plate rack structure has a traveling wheel 11 and a main drive wheel shaft 12. Specifically, the device base 10 is also welded with a vertically extending device frame 100A for fixing components.
[0033] The device base 10 moves on a predetermined ground via travel wheels 11. The travel wheels 11 are coaxially mounted on the main drive wheel axle 12, and a third output synchronous wheel 121 is mounted on the main drive wheel axle 12. Specifically, the device base 10 has four travel wheels 11. A pair of new travel wheels 11, which serve as the front wheels based on the direction of travel D, are respectively associated with a pair of main drive wheel axles 12. The pair of main drive wheel axles 12 are coaxially mounted, and the device base 10 adopts a front-wheel drive method.
[0034] The drive assembly 20 includes a drive motor 21 and a linkage shaft system 22 coupled to the output of the drive motor 21. Specifically, both the drive motor 21 and the linkage shaft system 22 are mounted on the device frame 100A.
[0035] The output shaft of the drive motor 21 is parallel to the linkage shaft system 22. A drive synchronous pulley 211 is coaxially arranged on the output shaft of the drive motor 21. An intermediate input synchronous pulley 221, a first intermediate output synchronous pulley 222, a second intermediate output synchronous pulley 223, and a third intermediate output synchronous pulley 224 are coaxially arranged on the linkage shaft system 22. The intermediate input synchronous pulley 221 forms a first synchronous belt pulley mechanism with the drive synchronous pulley 211 through a first synchronous belt 221a. The third intermediate output synchronous pulley 224 forms a fourth synchronous belt pulley mechanism with the third output synchronous pulley 121 through a fourth synchronous belt 224a.
[0036] Specifically, there is a pair of drive motors 21 and linkage shafts 22, that is, a pair of drive motors 21 drive a pair of main drive wheel shafts 12 respectively through the corresponding linkage shafts.
[0037] The soil turning assembly 30 includes a soil turning shaft 31 and a plurality of soil turning blades 32 passing through the soil turning shaft 31. A first output synchronous pulley 311 is coaxially arranged on the soil turning shaft 31. The first output synchronous pulley 311 forms a second synchronous belt pulley mechanism with the first intermediate output synchronous pulley 222 through a second synchronous belt 222a. In this embodiment, there is one first output synchronous pulley 311, which is located at one end of the soil turning shaft 31.
[0038] Specifically, the soil-turning blade 32 is arranged along a vertical plane and has multiple cutter heads arranged radially symmetrically in the circumferential direction. When the soil-turning shaft 31 rotates, the multiple cutter heads turn the soil on the predetermined ground at equal intervals.
[0039] like Figures 3 to 5 As shown, the sowing assembly 30 includes a seed storage container 41, a sowing base shell 42, a sowing shaft 43, and a sowing wheel 44. Specifically, the sowing assembly 40, a pair of traveling wheels 11 with the traveling direction D as the front wheels, and the soil turning assembly 30 are arranged sequentially along the traveling direction D.
[0040] The output shaft of the drive motor 21, the linkage shaft system 22, the soil turning shaft 31, and the sowing shaft 43 are parallel to each other.
[0041] The seed storage container 41 and the sowing base shell 42 are fitted together vertically and communicate with each other. The sowing shaft 43 is horizontally inserted through the sowing base shell 42. The sowing wheel 44 is coaxially arranged on the sowing shaft 43 and is located inside the seed storage container 41 and the sowing base shell 42. The circumference of the sowing wheel 44 is located inside both the seed storage container 41 and the sowing base shell 42.
[0042] The seed storage container 41 is shaped like a bucket with a narrowed bottom, and the seed storage container 41 is continuously connected to the top of the seed base shell 42 through the bottom opening.
[0043] The seeding base shell 42 is hollow and extends vertically. The bottom end of the seeding base shell 42 has a seeding opening (not shown in the figure) that opens outward and faces the predetermined ground. The seeding base shell 42 has a rotating wheel setting part 42a and a seeding part 42b that are integrally connected from top to bottom.
[0044] The rotating wheel setting part 42a communicates with the lower opening of the seed storage container 41, and the sowing rotating wheel 44 is rotatably set inside the rotating wheel setting part 42a. The sowing rotating wheel 44 and the inner wall of the rotating wheel setting part 42a form a wheel shell gap, which is smaller than the outer diameter of the predetermined seed. Specifically, the rotating wheel setting part 42a is a vertical disc, and in order to make the sowing rotating wheel 44 detachable, the top semi-circular part of the sowing setting part 42a is a detachable seed shell 421, and the top of the detachable seed shell 421 is formed with a connecting port and a connecting flange (not shown in the figure). The detachable seed shell 421 is connected to the bottom of the seed storage container 41 through the connecting flange, and the connecting port communicates with the lower opening of the seed storage container 41. A part of the sowing rotating wheel 44 located in the rotating wheel setting part 42a enters the interior of the seed storage container 41 through the connecting port, and the rest are all located inside the rotating wheel setting part 42a.
[0045] The sowing shaft 43 is coaxially provided with a second output synchronous pulley 431. The second output synchronous pulley 431 forms a third synchronous belt pulley mechanism with the second intermediate output synchronous pulley through a third synchronous belt 223a. Specifically, the sowing shaft 43 is fixed on the device frame 100A through a bearing seat 43A.
[0046] Multiple seed-receiving pits 441 are evenly formed on the circumference of the sowing wheel 44. The total width of the gap between the seed-receiving pits 441 and the wheel housing is greater than the outer diameter of the predetermined seed. Thus, when the seeds stored in the seed storage container 41 are put into the seed-receiving pits 441, the seeds in the seed-receiving pits 441 will be rotated and transferred to the sowing section 42 in sequence by the rotation of the sowing wheel 44, and sown at the sowing position on the predetermined ground.
[0047] like Figure 6 As shown, the sprinkler assembly 50 includes a sprinkler tank 51, a water pump 52, and a sprinkler nozzle 53.
[0048] The watering assembly 50, the seeding assembly 40 and the soil turning assembly 30 are sequentially arranged along the advancing direction D.
[0049] The watering row 53 is hollow and has a plurality of watering openings (not shown in the drawings) on the surface for connecting the outside and the inside. The input port of the water delivery pump 52 is connected with the watering tank 51, and the output port of the water delivery pump 52 is connected with the inside of the watering row 53. After the seeding assembly 40 completes the seeding on the predetermined ground, the watering row 53 waters the predetermined ground, i.e. waters the seeding position.
[0050] The soil filling assembly comprises a soil filling shaft (not shown in the drawings) and a soil filling wheel 61 coaxially arranged on the soil filling shaft, and the soil filling wheel 61 is in rolling contact with the predetermined ground. After the watering assembly 50 completes the watering on the predetermined ground, the soil filling wheel 61 levels the soil of the predetermined ground, i.e. levels the soil of the seeding position.
[0051] The above embodiment is a preferred case of the present application and is not used to limit the protection scope of the present application. Various modifications or changes made by those skilled in the art within the scope of the appended claims without creative labor are still within the protection scope of the present application.
