Description

Technical Field

[0001] This utility model relates to an agricultural machine, specifically a strip tiller with an openable and closable anti-clogging cover. Background Technology

[0002] In recent years, the area of ​​corn planted using conservation tillage techniques in my country has gradually increased, leading to the development of row tillage technology that combines straw retention with soil fertility improvement. This technology satisfies the agronomical requirements of preserving straw, improving soil fertility, and creating a level seedbed with a firm topsoil and compacted bottom, thus ensuring a high germination rate. However, existing row tillers often experience soil sticking. If the soil is slightly moist, a lot of soil adheres to the cover plate above the rotary tiller rollers, making operation difficult and accelerating wear on the rotary tiller blades. To address this issue, this invention designs a row tiller with an openable anti-clogging cover plate. When the soil is relatively dry, the cover plate is closed, and there is an inner rubber protective cover plate. Due to the elasticity of the rubber protective cover plate, the dry soil particles do not stick to it. When the soil is relatively moist, the rubber protective cover plate is removed, and the openable cover plate is opened. This expands the space above the rotary tiller rollers, preventing wet soil from sticking to the cover plate, effectively solving the problem. Utility Model Content

[0003] The purpose of this invention is to provide a strip tiller with an openable and closable anti-clogging cover to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A strip tiller with an openable and closable anti-blocking cover plate includes: a frame, a gearbox, a lower suspension frame, a subsoil shovel, a subsoil shovel seat, a weeding wheel, an upper suspension frame, a front cover plate fixing support plate, a cover plate hinge, a front cover plate, a coupling safety cover, a side gearbox, a cover plate buckle, a radiator, an oil tank, a press roller transmission box, a press roller drive hydraulic motor, a hydraulic pump, a coupling, a rear cover plate, a press roller bracket, a press roller, a soil covering disc bracket, and a soil covering disc. The invention comprises a disc, a depth-limiting wheel adjusting screw, a depth-limiting wheel mounting base, a depth-limiting wheel, a rear cover plate fixing support plate, a support plate fixing base, a rubber protective cover plate, a rotary tiller roller, a rotary tiller blade, and a cover plate fixing clip. Its characteristic feature is that a detachable rubber protective cover plate is located inside the front and rear cover plates. When the working soil is relatively dry, the front and rear cover plates are closed, revealing the rubber protective cover plate. When broken soil is applied to the rubber protective cover plate, due to the good elasticity of the rubber protective cover plate, the broken soil is shaken off and does not stick together.

[0005] Furthermore, the front and rear cover plates are opened forward to remove the inner rubber protective cover. The opening angle of the front cover plate is α, which can be selected within the range of 0 to 45°. By connecting the front cover plate fixing support plate to the support plate fixing seat, the front cover plate can be fixed at any angle between 0 and 45°. Similarly, the opening angle of the rear cover plate is β, which can also be selected within the range of 0 to 45°. By connecting the rear cover plate fixing support plate to the support plate fixing seat, the rear cover plate can be fixed at any angle between 0 and 45°. When the soil is sticky, this method is used because the inner rubber protective cover is removed, and the front and rear cover plates are opened forward, increasing the working space of the rotary tiller roller. The wet soil thrown out by the rotary tiller roller hits the opened cover plate with less force. By appropriately adjusting the opening angle of the front and rear cover plates, the wet soil is bounced back, greatly reducing the possibility of sticking. In addition, the opened front and rear cover plates are also easy to clean. Attached Figure Description

[0013] like Figures 1-5As shown, this utility model includes a frame 1, a lower suspension frame 3 is provided at an appropriate position at the front of the frame 1, and an upper suspension frame 7 is installed at the middle position of the upper part of the frame 1. The lower suspension frame 3 and the upper suspension frame 7 form a complete suspension mechanism. A gearbox 2 is installed at the middle position of the upper part of the frame 1. Couplings 19 are connected to the output shafts at both ends of the gearbox 2, and the couplings 19 are connected to the side gearboxes 12 on both sides. The other end of the side gearboxes 12 is connected to the rotary tiller rollers 31. The rotary tillers 32 are installed on the sheaths of the rotary tiller rollers 31. The gearbox 2, couplings 19, side gearboxes 12, rotary tiller rollers 31 and rotary tillers 32 constitute a strip tillage operation system. A deep tillage shovel seat 5 is provided at the middle position corresponding to the rotary tillage roller 31, and the deep tillage shovel 4 is installed on the deep tillage shovel seat 5 to complete the deep tillage operation of the implement; at the front part of the frame 1, corresponding to both ends of the rotary tillage roller 31, weed-removing wheels 6 are provided. The weed-removing wheels 6 clear the small amount of straw left by the return tillage machine to both sides, clearing a clean working area for the strip tillage operation; at both ends of the frame 1, on the outside of the gearbox 12, there are depth-limiting ground wheel mounting seats 26, and depth-limiting ground wheels 27 are installed on the depth-limiting ground wheel mounting seats 26. The depth-limiting ground wheel mounting seats 26 are also provided with depth-limiting ground wheel adjusting screws 25. By adjusting the depth-limiting ground wheel adjusting screws 25, the height of the depth-limiting ground wheel 27 can be adjusted. The height of the rotary tiller roller 31 is adjusted to ensure the strip tillage depth meets the requirement of 5-8 cm. A coupling safety cover 11 is installed on the upper part of the coupling 19. A front cover plate 10 and a rear cover plate 20 are installed between the upper part of the frame 1 and the coupling safety cover 11. The cover plate hinge 9 of the front cover plate 10 is installed on the front frame of the frame 1, and the cover plate buckle 13 of the front cover plate 10 is installed on the coupling safety cover 11. The cover plate buckle 13 and the cover plate fixing clip 33 on the front cover plate 10 form the locking mechanism of the front cover plate 10. Conversely, the cover plate hinge 9 of the rear cover plate 20 is installed on the coupling safety cover 11, and the cover plate buckle 13 of the rear cover plate 20 is installed on the coupling safety cover 11. On the rear frame of the machine frame 1, the cover plate buckle 13 and the cover plate fixing clip 33 on the rear cover plate 20 form the locking mechanism of the rear cover plate 20. When the working soil is relatively dry, it will not form a sticky sticking phenomenon. At this time, the front cover plate 10 and the rear cover plate 20 are covered and locked to the coupling safety cover 11 and the rear frame of the machine frame 1 by the cover plate buckle 13 and the cover plate fixing clip 33 respectively. A rubber protective cover plate 30 is installed inside the cover plate. The rubber protective cover plate 30 plays a protective role. The broken soil is stirred up by the rotary tiller roller 31 and thrown onto the rubber protective cover plate 30. Due to the elasticity of the rubber protective cover plate 30, the broken soil is bounced back to the ground and will not stick to the rubber protective cover plate 30.When the working soil is relatively wet, a sticky residue will form. In this case, remove the rubber protective cover plate 30 inside the cover plate, open the cover plate buckles 13 of the front cover plate 10 and the rear cover plate 20, open the front cover plate 10 forward around the cover plate hinge 9, and open the rear cover plate 20 forward around its cover plate hinge 9 as well. Connect the front cover plate fixing support plate 8 and the support plate fixing seat 29. Adjust the opening angle α of the front cover plate 10 to an angle between 0 and 45° as needed. This angle should be such that the soil hitting the front cover plate 10 is bounced back into the ground and not thrown out. Similarly, connect the rear cover plate fixing support plate 28 and the support plate. The fixed base 29 is connected, and the β angle of the rear cover plate 20 is adjusted to a range of 0 to 45° as needed. This angle is ideal so that the soil hitting the rear cover plate 20 is bounced back into the ground and not thrown out. At this time, since the rubber protective cover plate 30 is removed and the front cover plate 10 and the rear cover plate 20 are opened, the working space of the rotary tiller roller 31 is increased. The force of the soil fragments thrown up by the rotary tiller roller 31 hitting the front cover plate 10 and the rear cover plate 20 is reduced, and they are easily shaken off, thus preventing the formation of sticky soil. Hydraulic pumps 18 are installed on both sides of the gearbox 2, and an oil tank 1 is installed on the upper part of the gearbox 2. 5. A radiator 14 is installed at the rear of the frame 1. A soil covering disc support 23 is also installed on the rear beam of the frame 1. The soil covering disc 24 is installed on the soil covering disc support 23. The soil covering disc 24 gathers the soil thrown out by the rotary tiller roller 31 into the strip tillage belt so that a regular strip tillage belt can be formed in the subsequent compaction operation. A compaction roller support 21 is also installed on the rear beam of the frame 1. The compaction roller 22 is installed on the compaction roller support 21. A compaction roller drive box 16 is installed on the left side of the compaction roller 22. A compaction roller drive hydraulic motor 17 is set on the upper part of the compaction roller drive box 16. The hydraulic motor 17 drives the press roller 22 to rotate via the press roller transmission box 16, completing the pressing operation and forming a flat and strong strip of tillage. The gearbox 2 drives the hydraulic pump 18 to provide power to the press roller drive hydraulic motor 17. The oil tank 15 provides hydraulic oil to the hydraulic pump 18 and the press roller drive hydraulic motor 17. After the hydraulic oil has been used by the hydraulic pump 18 and the press roller drive hydraulic motor 17, it flows to the radiator 14, is cooled by the radiator 14, and then flows back to the oil tank 15. The oil tank 15, the hydraulic pump 18, the press roller drive hydraulic motor 17, and the radiator 14 constitute the hydraulic system of the implement.
