Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a multifunctional agricultural tillage machine. Background Technology

[0002] Agricultural tillage machines are agricultural machines used for soil preparation, land preparation before sowing, and field management. Their core functions include loosening soil, weeding, tilling, ditching, sowing, and fertilizing. Their main classifications include small handheld, walking, large tractor-mounted, and tracked special types. Based on their characteristics, they can be used appropriately in different scenarios.

[0003] Chinese Publication No. CN108464071A discloses a multi-functional agricultural tillage machine, including a traveling vehicle, a soil loosening device, a ditching and sowing device, a soil covering device, a mulching device, and a lifting device. The soil loosening device is located at the front end of the traveling vehicle. The ditching and sowing device, the soil covering device, and the mulching device are sequentially arranged at the lower end of the traveling vehicle. A swing frame extending to both sides of the mulching device is also provided at the lower end of the traveling vehicle. A plowshare is mounted on the swing frame. A support frame is pivotally connected to the rear end of the traveling vehicle. The rotating roller of the mulching device is rotatably mounted on the support frame. A lifting device for driving the mulching device to rise and fall is also provided at the rear end of the traveling vehicle. The multi-functional agricultural tillage machine provided in this application solves the technical problems of existing agricultural machinery having limited functions, being time-consuming and labor-intensive, and being unable to flexibly switch between situations requiring and not requiring mulching.

[0004] Although the aforementioned patents have solved the technical problems of existing agricultural machinery being single-function, time-consuming, labor-intensive, and unable to flexibly switch between situations where mulch needs to be laid and those where it does not, by utilizing components such as walking vehicles and lifting devices, it is still necessary to consider the issue of sowing spacing during the tilling and sowing process, as different plant growth conditions require different considerations. If the spacing between plants is too small, it will reduce the absorption efficiency of water and minerals in the soil, leading to situations such as tangling, lack of fertilizer, and drought.

[0005] In view of this, we propose a multi-functional agricultural tillage machine. Summary of the Invention

[0040] like Figure 7-8As shown, the feeding device 4 includes multiple first guard plates 41. The first guard plates 41 are fixedly connected to the side of the protective cover 21 away from the extension plate 26. The second transmission wheel 252 is rotatably connected to the outer wall of the first guard plate 41. The multiple first guard plates 41 are fixedly connected to both sides of the fixed cover 3. The inner side of the first guard plate 41 is fixedly connected to a first fixed plate 42. The first fixed plate 42 is fixedly connected to a second fixed plate 421 on the side away from the first guard plate 41. A square hole 422 is opened at the middle of the lower end of the second fixed plate 421. A third slider 423 is slidably connected in the square hole 422. Multiple triangular material dividing parts 43 are fixedly connected between the two third sliders 423 by a crossbar. A material dividing plate 43 is provided below each of the multiple triangular material dividing parts 43. 1. The material distribution plate 431 is fixedly connected to the inner wall of the discharge hopper 14. The second fixed plate 421 has a fixed block 424 fixedly connected to the middle of the side near the first guard plate 41. A spring 425 is fixedly connected between the fixed block 424 and the third slider 423. Multiple conveyor belts 44 are arranged between the two second fixed plates 421. Multiple conveyor wheels 442 are arranged on the inner wall of the multiple conveyor belts 44. The conveyor belts 44 are sleeved on the outer wall of the multiple conveyor wheels 442. The second drive wheel 252 is fixedly connected to the end of the lower conveyor wheel 442 on one side. Multiple conveyor plates 441 are fixedly connected to the outer wall of both conveyor belts 44. The positions of the two conveyor plates 441 fit each other, and the ends of the conveyor plates 441 located on the upper inner side of the conveyor belts 44 are attached to each other.

[0041] Among them, the conveyor belt 44 is supported by multiple conveyor wheels 442. The side of the two conveyor belts 44 that are close to each other has a smaller upper space width and a gradually larger lower space width. In the position where the upper space width of the two conveyor belts 44 is smaller, the ends of the conveyor plates 441 on both sides are in a closed state.

[0042] like Figures 8-9As shown, the ends of the conveyor wheels 442 at the middle of both sides are fixedly connected to spur gears 443, and the two spur gears 443 mesh with each other. The end of the lower conveyor wheel 442 is fixedly connected to a second rotating wheel 444. A second transmission belt 445 is fitted on the outer wall of the second rotating wheel 444. A third rotating wheel 45 is provided on the inner wall of the end of the second transmission belt 445 away from the second rotating wheel 444.

The third rotating wheel 45 is rotatably connected to the outer wall of the first guard plate 41 away from the protective cover 21. The third rotating wheels 443 on both sides are connected to the second rotating wheel 444. A coating wheel 451 is rotatably connected between the two plates.

A restoration plate 454 is fixedly connected to the lower end of the second guard plate 452. The restoration plate 454 is located on one side of the discharge funnel 14. A sliding strip 46 is fixedly connected to the top of the second guard plate 452. The sliding strip 46 is electrically slidably connected to the inner wall of the first guard plate 41 on both sides.

[0043] Therefore, it can be concluded that when agricultural tillage machines are in operation, such as Figures 2-4 As shown, during the preparation stage, the staff connects the two ends of the water jet 261 to the external water tank and the medicine tank respectively. After pouring the seeds into the feed funnel 11, the staff installs the device on the tractor or tracked vehicle and drives the device to move. After arriving at the field, the device starts to work. The device first enters the field with the water jet 261 and sprays water according to the dryness of the field. Then, under the internal transmission of the transmission component 2, the tillage wheel 24 and the tillage shovel 241 are driven to till the field.

[0044] Driven by motor 12, the first rotating wheel 121 rotates, and at the same time, the first rotating wheel 121 drives multiple sprockets 23 and chains 231 to rotate together. During the rotation of the chain 231, the second slider 222 will move together. When the second slider 222 moves from the upper position of the triangular chain 231 to the lower position, the second slider 222 will slide in the second strip hole 221 inside the fixed bar 22, and together drive the fixed bar 22, the first slider 214, the sliding plate 215 and the tillage wheel 24 to move down. At this time, the tillage wheel 24 gradually moves down to the top position of the field, and the tillage shovel 241 is inserted into the field. As the equipment is driven to continue moving, it will drive the tillage shovel 241 to rotate. At this time, the soil shoveled by the tillage shovel 241 will slide back onto the field after the tillage wheel 24 rotates, ensuring that the seeding can be carried out at a fixed interval after tilling.

[0045] It should be noted that when the second slider 222 moves with the chain 231 to the position of the triangular base of the triangular chain 231, it will move horizontally for a period of time. At this time, the second slider 222 will not drive the first slider 214, the sliding disk 215 and the tillage wheel 24 to move up and down. During this process, the tillage wheel 24 will perform tillage operation on the area to be sown, realizing intermittent tillage of the field, which can be coordinated with subsequent sowing.

[0046] At the same time, the sprocket 23 at the lower end will drive the first transmission wheel 25 to rotate, and the first transmission wheel 25 will drive the second transmission wheel 252 to rotate together through the first transmission belt 251. During the rotation of the second transmission wheel 252, the conveyor wheel 442 will also rotate. The conveyor wheel 442 will drive multiple conveyor wheels 442 to rotate together through the transmission of the conveyor belt 44. At this time, when the seeds fall from the feed hopper 11 into the small space at the upper end of the conveyor belt 44, they are gradually conveyed downwards by the obstruction of the conveyor plate 441.

[0047] During the process of seeds being conveyed downward by the conveyor plate 441, when the conveyor plate 441 moves to the lower inner end of the conveyor belts 44 on both sides, as the width of the conveyor belts 44 on both sides increases, the conveyor plates 441 on both sides gradually unfold and open from a closed state. At this time, the seeds flow downward from the opening formed by the conveyor plates 441 on both sides. When they flow to the position of the triangular dividing piece 43, they are blocked by the triangular dividing piece 43 and the dividing plate 431 at its bottom, and the seeds are divided into multiple streams and fall into the discharge funnel 14, and finally fall onto the field. The intermittent sowing is achieved by the batch conveying of the conveyor belts 44 and the conveyor plate 441 to prevent the sowing interval from being too small, which would affect the growth of the plants.

[0048] It should be noted that the two conveyor belts 44 rotate in opposite directions due to the meshing of the two spur gears 443. Under the tension of the spring 425, the triangular dividing member 43 always has an upward force. When the conveyor plate 441 moves down to the position of the triangular dividing member 43, it presses the member down. At this time, the spring 425 is stretched. As mentioned above, when the conveyor plate 441 presses the triangular dividing member 43 down to a position where the width of the conveyor belt 44 gradually increases, the conveyor plate 441 also gradually forms an opening. The opening formed by the triangular material divider 43 continues to move downward from both sides and no longer exerts pressure on the triangular material divider 43. At this time, under the action of the spring 425, the triangular material divider 43 rebounds and moves upward, producing an up-and-down vibration effect. At this time, the seeds that have formed the opening will first fall to the top of the triangular material divider 43, and under the effect of the up-and-down vibration of the triangular material divider 43, the seeds will be shaken off quickly to prevent the seeds from being left on the top and dying, which would affect the quality of subsequent seeds. After the triangular material divider 43 moves to the topmost position, it will be moved again by the action of the next conveyor plate 441.

[0049] In addition, after sowing, the soil piled up by the tillage shovel 241 is pushed and leveled using the restoration plate 454, and the soil is then covered back onto the seeds in the field.

[0050] At the same time, the conveyor wheel 442 will drive the second rotating wheel 444 to rotate. The second rotating wheel 444 will drive the third rotating wheel 45 and the film covering wheel 451 to rotate through the second transmission belt 445. After sowing, the field will be covered with film. After sowing, the sliding bar 46 and the cutting tooth 453 will be moved down by the electric drive of the first guard plate 41, and the film will be cut by the cutting tooth 453.
