Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, specifically to a rotary tillage and fertilization device for millet sowing. Background Technology

[0002] Millet, as an important coarse grain crop in the arid and semi-arid regions of northern my country, is characterized by drought resistance, tolerance to poor soil, and a short growing season. It plays an important role in ensuring food security and diversifying the agricultural planting structure. However, in the process of millet cultivation, the synergistic effect of rotary tillage and fertilization directly affects its germination rate, growth status, and final yield.

[0003] In existing technologies, rotary tillage and fertilization devices typically consist of a rotary tiller shaft, a fertilizer box, and a transmission mechanism. The rotary tiller shaft breaks up the soil through high-speed rotation, while the fertilizer box applies fertilizer to the soil via gravity conveying. The connection between the rotary tiller blades and the shaft is rigidly fixed. When the rotary tiller blades come into contact with impurities such as stones or hard roots in the soil, these impurities impact the blades and shaft. At the same time, roots and clay become entangled and adhere to the outer wall of the rotary tiller blades, causing the shaft to jam during rotation and preventing the rotary tiller from working properly. To address this issue, a rotary tillage and fertilization device for millet sowing has been designed. Utility Model Content

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] 1. This utility model features a sliding plate and a cleaning plate at the bottom of the rotary tiller. When the operator rotates the rotary tiller shaft, the cleaning plate intermittently cleans the rotary tiller blades. The rotating shaft drives a rotating disk to rotate circumferentially, which in turn pushes a sliding wheel to slide horizontally back and forth. The sliding wheel then pushes a push rod and a push block to slide back and forth. The push block then pushes the sliding plate to slide. Finally, the sliding plate returns to its original position due to the elasticity of a spring rod. The reciprocating motion of the spring rod and push rod enables the cleaning plate and wire brush to slide back and forth, intermittently cleaning the surface of the rotary tiller blades, removing stubborn clay and improving the tilling efficiency.

[0017] 2. This utility model features a cleaning component installed on the inner wall of the rotary tiller. When the cleaning plate and wire brush perform intermittent cleaning through reciprocating motion, the cleaning component can clean the wire brush during these intermittent periods, further improving the cleaning efficiency of the wire brush. As the wire brush and cleaning plate move away from the rotary tiller blades, the cleaning plate slides and scrapes against the inner wall of the scraper, further removing the soil cleaned by the wire brush and improving its cleanliness. The scraped soil then falls onto the filter plate for further filtration, separating recyclable fine soil for reuse. Attached Figure Description

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-6 The diagram illustrates a rotary tillage and fertilization device for millet sowing according to an embodiment of the present invention. It includes a rotary tillage frame 1, a rotary tillage shaft 2 rotatably connected to the bottom of the frame 1, two rotating disks 5 symmetrically fixed to the outer wall of the shaft 2, and two push rods 501 symmetrically slidably connected to the inner wall of the frame 1, near one end of the rotating disks 5. Two sliding wheels 503 are fixedly connected to one end of each push rod 501, with the outer wall of each wheel 503 slidably connected to the inner wall of the rotating disks 5. The end of the push rod 501 furthest from the sliding wheels 503... A push block 504 is fixedly connected. A sliding plate 601 is slidably connected to the bottom of the rotary tiller 1 at the end away from the rotary tiller shaft 2. Multiple spring rods 602 are fixedly connected to the outer wall of the sliding plate 601. A cleaning plate 603 is fixedly connected to the end of the sliding plate 601 away from the spring rods 602. A wire brush 604 is fixedly connected to the outer wall of the cleaning plate 603. A baffle 6 is fixedly connected to the outer wall of the rotary tiller 1. The inner wall of the baffle 6 is slidably connected to the outer wall of the multiple spring rods 602. A cleaning component 7 is provided on the outer wall of the wire brush 604.

[0033] Among them, a plurality of rotary tillage blades 201 are fixedly connected to the outer wall of the rotary shaft 2 at the end away from the rotary disk 5.

[0034] It should be noted that after the rotating disk 5 rotates, it pushes the sliding wheel 503 to slide horizontally back and forth. The sliding wheel 503 then pushes the push rod 501 to slide horizontally back and forth on the inner wall of the guide block 502. The guide block 502 then pushes the push block 504 to slide horizontally back and forth. When the push block 504 slides towards the sliding plate 601, it pushes the sliding plate 601 to continue sliding. At this time, the sliding plate 601 will squeeze the spring rod 602, and at the same time, the sliding plate 601 drives... The cleaning plate 603 and the wire brush 604 move away from the rotary tiller blade 201. When the push block 504 and the push rod 501 slide in opposite directions, the sliding plate 601 and the spring rod 602 lose their pushing force. The sliding plate 601 will rebound under the elastic force of the spring rod 602. The sliding plate 601 drives the cleaning plate 603 and the wire brush 604 to slide in opposite directions. After the sliding plate 601 returns to its original position, the wire brush 604 contacts the rotary tiller blade 201 for cleaning, thereby realizing the intermittent cleaning of the rotary tiller blade 201 by the wire brush 604.

[0035] like Figure 1 As shown, it illustrates a rotary tillage and fertilization device for millet sowing in another embodiment of the present invention. A connecting frame 3 is fixedly connected to the upper surface of the rotary tillage frame 1, and two connecting blocks 301 are symmetrically fixedly connected to one end of the rotary tillage frame 1 near the connecting frame 3.

[0036] It should be noted that the connecting frame 3 is fixedly supported at the bottom of the rotary tiller 1, and a connecting plate is provided at the top of the connecting frame 3. Two connecting blocks 301 are symmetrically fixed at the front end of the rotary tiller 1. The connecting frame 3 and the connecting blocks 301 need to be connected and fixed to the back of the tractor by bolts. Through the connection of the connecting frame 3 and the connecting blocks 301, the tractor can pull the rotary tiller 1 to perform rotary tillage in the field.

[0037] like Figure 2 As shown, it illustrates a rotary tillage and fertilization device for millet sowing in another embodiment of the present invention. A transmission box 401 is fixedly connected to the upper surface of the rotary tillage frame 1 at one end near the connecting frame 3. Two rotating shafts 4 are symmetrically rotatably connected to the outer wall of the transmission box 401, and two gearboxes 402 are symmetrically fixedly connected to the outer wall of the rotary tillage frame 1.

[0038] It should be noted that the inner wall of the transmission box 401 is provided with multiple meshing bevel gears. Rotary shafts 4 are rotatably connected to both sides of the transmission box 401. After the tractor and rotary tiller 1 are installed, the rotary shaft on the back of the tractor needs to be connected to the top of the transmission box 401. When the tractor is started, the transmission box 401 drives the rotary shaft to rotate. The rotary shaft achieves the meshing and rotation of the internal bevel gears through the transmission box 401. Finally, the transmission box 401 rotates the power transmission rotary shaft 4.

[0039] like Figure 2 As shown, it illustrates a rotary tillage and fertilization device for millet sowing in another embodiment of the present invention. Two rotating shafts 4 extend into the inner walls of two gearboxes 402 at one end away from the transmission box 401. The extended ends of the rotating shafts 4 are connected to the inner walls of the gearboxes 402 in a driving connection. Both ends of the rotary tillage shaft 2 extend into the inner walls of the two gearboxes 402. The extended ends of the rotary tillage shaft 2 are connected to the inner walls of the gearboxes 402 in a driving connection.

[0040] It should be noted that multiple gears mesh on the inner wall of the gearbox 402. The top of the gearbox 402 is the driving end, and the bottom of the gearbox 402 is the driven end. The driving end of the gearbox 402 is connected to both ends of the rotating shaft 4, and the driven end of the gearbox 402 is rotatably connected to both ends of the rotary tillage shaft 2. When the rotating shaft 4 rotates, the rotating shaft 4 transmits power to the inner wall of the gearbox 402 through the driving end. Then, the gearbox 402 transmits power to both ends of the rotary tillage shaft 2 through the driven end. Finally, the rotary tillage shaft 2 drives the rotary tillage blades 201 to rotate through the transmission, and the rotating rotary tillage blades 201 till the land.

[0041] like Figure 6 As shown, it illustrates a rotary tillage and fertilization device for millet sowing in another embodiment of the present invention. Two guide blocks 502 are symmetrically fixedly connected to the inner wall of the rotary tillage frame 1 and to one end near the sliding wheel 503. The inner wall of the guide block 502 is slidably connected to the outer wall of the push rod 501.

[0042] It should be noted that the two guide blocks 502 are symmetrically fixed on the inner wall of the rotary tiller 1. The inner wall of the guide block 502 is provided with a sliding groove, which is slidably connected to the outer wall of the push rod 501. When the rotary tiller shaft 2 rotates and pushes the push rod 501 to slide horizontally, the push rod 501 will slide horizontally back and forth on the inner wall of the guide block 502. With the support of the guide block 502, the sliding of the push rod 501 is stably guided.

[0043] like Figure 4 As shown, it illustrates a rotary tillage and fertilization device for millet sowing in another embodiment of the present invention, including a fixed plate 702 fixedly connected to the inner wall of the rotary tillage frame 1 and located near one end of the rotary cleaning plate 603, and a scraper 701 fixedly connected to the inner wall of the fixed plate 702.

[0044] The inner wall of the scraper 701 is slidably connected to the outer wall of the wire brush 604, and a filter plate 703 is fixedly connected to the inner wall of the rotary tiller 1 at one end near the scraper 701.

[0045] It should be noted that the scraper 701 is fixedly mounted on the inner wall of the rotary tiller 1 by the fixing plate 702. The inner wall of the scraper 701 has multiple scraping holes arranged in it. The inner wall of the scraping holes is slidably connected to the outer wall of multiple wire brushes 604. When the push rod 501 pushes the wire brushes 604 to slide horizontally back and forth, the wire brushes 604 will slide on the inner wall of the scraping holes through the back and forth motion. The soil is scraped off by the sliding of the scraping holes and the wire brushes 604. The scraped soil will fall onto the upper surface of the filter plate 703 for filtration. The soil is further divided into recyclable fine soil through filtration.

[0046] like Figure 3As shown, it illustrates a rotary tillage and fertilization device for millet sowing in another embodiment of the present invention. A support plate 101 is fixedly connected to the top of the rotary tillage frame 1, a fertilizer frame 8 is fixedly connected to the top of the support plate 101, and a plurality of fertilizer discharge components 801 are fixedly connected to the bottom of the fertilizer frame 8.

[0047] The bottom end of the fertilizer discharge component 801 is fixedly connected to a guide pipe 803, and the inner wall of the support plate 101 and the end located near the guide pipe 803 are fixedly connected to a guide plate 802.

[0048] It should be noted that the fertilizer discharge unit 801 consists of a fertilizer discharge wheel and a frame. The fertilizer discharge wheels of multiple fertilizer discharge units 801 are connected by a rotating rod. During fertilization, the fertilizer frame 8 conveys the fertilizer to the inner wall of the fertilizer discharge unit 801 by gravity. The fertilizer discharge unit 801 then conveys the fertilizer to the guide pipe 803 for discharge through the fertilizer discharge wheel. The fertilizer falls through the guide pipe 803 onto the upper surface of the guide plate 802, and is then guided by the guide plate 802 to the surface of the tilled soil.

[0049] Working principle and usage process of this utility model:

[0050] The specific operation is as follows: the operator starts the tractor and pushes the rotary tiller 1 to perform rotary tillage. After the tractor starts, the transmission box 401 drives the rotating shaft 4 to rotate. The rotating shaft 4, after rotating, drives the inner wall of the gearbox 402 to transmit power. Then, the gearbox 402 drives the rotary tillage shaft 2 to rotate. When the rotary tillage shaft 2 rotates, it drives the rotating disk 5 and the rotary tillage blades 201 to rotate. The rotation of multiple rotary tillage blades 201 performs rotary tillage on the land. At the same time, after the rotating disk 5 rotates, it pushes the sliding wheel 503 to slide horizontally back and forth. The sliding wheel 503 then pushes the push rod 501 to slide horizontally back and forth on the inner wall of the guide block 502. The guide block 502 then pushes the push block 504 to perform horizontal back and forth sliding. The horizontal reciprocating sliding mechanism pushes the sliding plate 601 as it slides towards it. This pushes the sliding plate 601, causing it to continue sliding. Simultaneously, the sliding plate 601 compresses the spring rod 602, and the cleaning plate 603 and wire brush 604 move away from the rotary tiller blade 201. When the pusher 504 and push rod 501 slide in opposite directions, the sliding plate 601 and spring rod 602 lose their pushing force. The sliding plate 601 rebounds under the elastic force of the spring rod 602, causing the cleaning plate 603 and wire brush 604 to slide in opposite directions. After the sliding plate 601 returns to its original position, the wire brush 604 contacts and cleans the rotary tiller blade 201, thus achieving intermittent cleaning of the rotary tiller blade 201 by the wire brush 604.

[0051] When the sliding plate 601 slides under the pushing force of the pusher block 504, the sliding plate 601 drives the wire brush 604 to slide away from the rotary tiller blade 201. At this time, the wire brush 604 will slide on the inner wall of the scraper plate 701. While sliding, the scraper plate 701 will further clean the soil clods remaining on the surface of the wire brush 604, thereby cleaning the wire brush 604. The scraped soil will fall to the top of the filter plate 703 and be filtered out by the filter plate 703. The recovered fine soil can be further used for seed covering to form a loose and breathable covering layer, thus achieving recycling while cleaning the wire brush 604.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
