Description
Technical Field
[0001] The utility model relates to the technical field of wheat seeders, in particular to a floating adjustable straw removing device. Background Art
[0002] Rice and wheat are the main crop rotation methods for grain production in Jiangsu Province. When farming in the usual way, the rice straw from the previous crop is broken up and returned to the field, often located in the shallow soil layer or floating on the soil surface. When the subsequent wheat crop is sown, the seeds cannot fully contact the soil, resulting in problems such as late emergence and low germination rate, which affects wheat yield.
[0003] To solve this problem, the prior art discloses an intelligent deep fertilization seeder with rotary tillage in a clean area of a full straw stubble field. This seeder discloses a straw auger assembly, which serves as a straw cleaning mechanism for returning straw to rows. This straw auger assembly includes two augers arranged on the left and right, and the two parallel augers on the left and right correspond to three sowing rows respectively. Before sowing, the straw auger assembly first collects the straw on the surface of the sowing row and transports it to the outside of the side sowing row, so as to achieve the effect of straw cleaning and ensure efficient sowing.
[0004] However, the use of this type of auger to transport and collect straw also has the following disadvantages: 1. After the straw enters the auger, the straw will be compacted during the transportation process, and the straw discharged from both sides will eventually be arranged in rows. After the straw is compacted, it is not fluffy enough, and the thickness of the straw stack is also large, which can no longer achieve the purpose and effect of straw covering; 2. When the auger is used to transport the straw, the length of the auger is generally large, and the augers on both sides correspond to multiple rows of sowing rows. After the straw is collected, the straw is concentrated on both sides of the multiple rows of sowing rows, and the straw coverage rate of the multiple rows of sowing rows decreases as a whole, and the purpose and effect of straw covering still cannot be achieved; 3. This type of auger structure needs to be close to the ground to collect the straw, and the soil surface is uneven, so the ground straw of the sowing row may not be collected cleanly.

DETAILED DESCRIPTION
[0021] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.
[0022] like Figure 4 As shown, the floating adjustable straw-stripping device is installed at the front end of the wheat seed drill frame, including a stripping mounting frame 1, which serves as the mounting base of the device. In this embodiment, the stripping mounting frame 1 is fixedly connected to the front of the wheat seed drill, corresponding to the sowing row one by one, and is used to clean the straw of the sowing row first. After the straw is cleaned, a series of operations such as rotary tillage, fertilization, sowing, and suppression are performed. This machine can remove the straw of the sowing row under the condition of straw covering and returning to the field, realize the sowing operation under the condition of no straw, and greatly improve the sowing quality; the core of the technology of this application is to cleverly open up a straw concentrated covering area in the wheat field, so that the straw not only does not interfere with wheat sowing, but also provides a better microenvironment for wheat growth. By returning the crushed straw to both sides of the row, the soil of the cleaned sowing belt is deep loosened and shallowly plowed for sowing, the requirements of protective tillage and less tillage and land preparation under the condition of straw covering are met, the content of straw in the soil of the seedling belt is reduced, and the seeds are sown into the soil. The rear-placed suppression roller ensures the soil shaping and suppression effect.
[0023] See also Figures 1 to 3Two straw external rotation components are installed on the separating mounting frame 1 and are arranged side by side. The straw external rotation components are tilted toward the front and lower part of the whole machine. An angle-adjustable device for controlling the separating mounting frame 1 to drive the straw external rotation components to tilt forward and downward is provided between the separating mounting frame 1 and the frame; the two straw external rotation components are located on both sides of the corresponding sowing row and the adjacent sides of the two straw external rotation components are overlapped. An external rotation separating driving device is also provided between the separating mounting frame 1 and the straw external rotation components. The external rotation separating driving device drives the two straw external rotation components to rotate outwards respectively to cooperate in separating the surface straw of the sowing row to the space between the two sides of the sowing row. Before sowing wheat, the inclination angle between the straw external rotation component and the ground is adjusted by the angle-adjustable device to ensure that the straw external rotation component can contact the ground surface; when removing the straw, the external rotation removal driving device drives the two straw external rotation components to move simultaneously, and the straw external rotation components rotate outward to remove the surface straw on the sowing row outward to the space between the rows on both sides of the sowing row. Since the adjacent sides of the two straw external rotation components overlap, the sowing row is fully covered, avoiding areas on the surface of the sowing row that are missed.
[0024] See also Figure 1 and Figure 4 The angle adjustable device includes a mounting frame compression spring 2 arranged between the frame and the disengagement mounting frame 1 for controlling the disengagement mounting frame 1 to tilt backward and downward, one end of the mounting frame compression spring 2 is connected to the frame, and the other end of the mounting frame compression spring 2 is threadedly connected to the disengagement mounting frame 1 through an adjusting screw 3, and a threaded rod seat 4 threadedly connected to the adjusting screw 3 is provided on the disengagement mounting frame 1, one end of the adjusting screw 3 is threadedly connected to the threaded rod seat 4, and the other end is hooked and connected to the mounting frame compression spring 2 for easy disassembly and adjustment.
[0025] When the tilt angle needs to be adjusted, the contraction state of the mounting frame compression spring 2 can be adjusted by rotating the adjusting screw 3. The mounting frame compression spring 2 is the main component supporting the disengagement mounting frame 1. The device mainly adjusts the tilt angle through the adjusting screw 3, and the mounting frame compression spring 2 is used to support the disengagement mounting frame 1 upward. Since the mounting frame compression spring 2 has a certain amount of contraction, in actual use, the straw external rotation component is tilted forward and downward. Therefore, when moving forward to disengage the straw, if an obstacle is encountered in front of the straw external rotation component, the straw external rotation component will be pushed backward. At this time, due to the presence of the mounting frame compression spring 2, the straw external rotation component has a certain amount of floating, which can reduce the destructive force on the straw external rotation component.
[0026] In this embodiment, the angle adjustment range required by the straw external rotation component is relatively small. Generally, after the angle adjustment is completed, it can remain basically unchanged. However, in special circumstances, such as long slope routes, it is necessary to adjust the angle appropriately to ensure better contact with the soil ground.
[0027] The straw external rotation component includes a straw external rotation wheel 6, the upper part of the straw external rotation wheel 6 is connected to an external rotation wheel shaft 7, the top of the external rotation wheel shaft 7 is rotatably mounted on the separation mounting frame 1, and the bottom outer circumference of the straw external rotation wheel 6 is installed with a straw separation brush 8, and the external rotation separation driving device drives the external rotation wheel shaft to rotate, thereby driving the straw external rotation wheel 6 and the straw separation brush 8 to rotate. The adjacent sides of the straw separation brushes 8 on the left and right straw external rotation components are arranged in an interlaced and overlapping manner to avoid the area in the middle of the sowing row from being missed. The straw separation brush 8 is a separation elastic comb tooth with the bottom end extending obliquely toward the periphery. The separation elastic comb tooth is made of a rubber material with certain flexibility and toughness, and has good wear resistance. In the present embodiment, since this type of elastic comb teeth for removing straw have certain flexibility and good deformability, the profiling effect can be achieved without adding a profiling device. When the soil surface is uneven, the comb teeth can deform naturally and adapt to the uneven soil better, without affecting the straw removal effect and without hard collision with compacted soil blocks. Especially when used in conjunction with the mounting frame compression spring 2 in the angle adjustable device, it can better adapt to the soil and better remove the straw from the surface of the sowing row. Compared with the prior art auger structure, it has the advantages of simplified structure and low cost, and has its own profiling effect, and the removal effect is better.
[0028] The straw external rotation wheel 6 is detachably fixedly connected to the external rotation wheel shaft by bolts, so that the worn elastic comb teeth can be easily replaced. When straw cleaning is not needed, the straw external rotation component can also be removed without affecting the rotary tillage and sowing operations of the wheat seeder.
[0029] The straw epicyclic wheel 6 is tilted toward the front of the whole machine, and the front bottom end of the straw-removing brush 8 serves as a sweeping brush action part, the height of which is lower than the soil plane and in contact with the ground to remove the straw on the surface. In this embodiment, the frontmost sweeping brush action part that can contact the ground is to reduce the friction between the spring teeth and the ground in the ineffective stage, so as to increase the service life of the spring teeth.
[0030] The extrorotatory expulsion drive device comprises an expulsion drive motor 9 mounted on the expulsion mounting frame 1, wherein a driving gear 10 is mounted on one of the extrorotatory wheel shafts 7, and a driven gear 11 is mounted on the other extrorotatory wheel shaft 7, wherein the driving gear 10 and the driven gear 11 are meshed with each other, and the corresponding extrorotatory wheel shaft 7 mounted with the driving gear 10 is connected to the output end of the expulsion drive motor 9. The expulsion drive motor 9 can also be a rotary hydraulic cylinder. When the expulsion drive motor 9 is working, it drives the driving gear 10 to rotate, and then drives the driven gear 11 to rotate, and the driving gear 10 and the driven gear 11 are respectively fixed on the corresponding extrorotatory wheel shafts 7, and the two extrorotatory wheel shafts 7 are driven to rotate, so that the straw extrorotatory wheel 6 and the straw expulsion brush 8 mounted thereon rotate accordingly. The straw expulsion brush 8 rotates outwardly around the axis to expel the surface straw outwardly.
[0031] In order to prevent the straw that is pushed away from the outside from being brought back into the sowing row by the rotating straw-pushing brush 8, the outer ends of the two straw outer-rotating wheels 6 are respectively installed with outer-rotating straw-blocking devices, and the outer-rotating straw-blocking devices are arranged on the outer sides of the corresponding straw outer-rotating wheels 6, and the length direction is parallel to the sowing belt, forming a straw-blocking and straw-removing surface on the outer side of the sowing belt. In the process of straw-pushing away, there is a phenomenon that the straw is retained between the spring teeth, and the straw is easily brought back into the sowing row, so that the straw cleaning effect cannot be optimized. The straw-blocking and straw-removing surface is arranged on the outer side of the straw outer-rotating wheel 6, which can prevent the straw that splashes backwards from moving toward the sowing row, and is used to reduce the straw from entering the sowing row.
[0032] The externally rotating straw-blocking device includes a straw-blocking mounting frame 12 fixed on the straw-blocking mounting frame 1, and an externally rotating straw-blocking comb tooth 13 is installed on the straw-blocking mounting frame 12. A plurality of the externally rotating straw-blocking comb teeth 13 are arranged along the length direction of the sowing belt to form the straw-blocking and straw-removing surface on the outer side of the straw-blocking brush 8. The outer end of the straw-blocking brush 8 passes through the straw-blocking and straw-removing surface of the externally rotating straw-blocking comb tooth 13 and extends to the outer side of the straw-blocking and straw-removing surface. The straw-blocking and straw-removing surface also serves as a sweeping brush cleaning part for cleaning the externally rotating straw-blocking comb teeth 13. A plurality of the outer rotating straw-blocking comb teeth 13 are arranged in a row to prevent the straw from splashing backwards and entering the sowing row. At the same time, since the outer rotating straw-blocking comb teeth 13 and the elastic comb teeth for removing are both tooth structures, and the outer end of the straw-sweeping brush 8 passes through the outer side of the straw-blocking and straw-removing surface, a part of the teeth between the two can cross. At this time, even if there is straw left between the straw-sweeping brushes 8, after passing through the straw-blocking and straw-removing surface, when the straw-sweeping brush 8 crosses and contacts with a plurality of the outer rotating straw-blocking comb teeth 13, the gap between the straw-sweeping brushes 8 will open, the remaining straw will fall off, and the outer rotating straw-blocking comb teeth 13 will also fork in between the straw-sweeping brushes 8, achieving the effect of cleaning the straw. In addition, the straw-removing surface can also block the straw splashed from the other side when cleaning straw, and avoid the straw from running around between adjacent rows when cleaning multiple rows at the same time, affecting the straw cleaning effect.
