Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The discharger driving structure of the agricultural machine shown in the attached drawing 1 is used for driving the discharger of the agricultural machine, and the discharger of the agricultural machine can continuously distribute agricultural materials such as seeds and fertilizers with stable flow, so that the materials can be uniformly put in when the agricultural machine spreads the seeds or the fertilizers. The discharging frequency of the discharger is influenced by the rotating speed of the main shaft of the discharger, and the faster the rotating speed of the main shaft is, the faster the discharging frequency of the discharger is, and the more agricultural materials are discharged.
The discharger driving structure comprises a land wheel 1, a transmission relation is arranged between the land wheel 1 and a main shaft of the discharger, when the agricultural machine runs, the land wheel 1 is always contacted with the ground, the interaction relation between the ground and the land wheel 1 can enable the land wheel 1 to rotate spontaneously along with the movement of the agricultural machine in the ground, and the faster the agricultural machine moves, the faster the rotating speed of the land wheel 1 is, so that the proportional relation between the rotating speed of the land wheel 1 and the moving speed of the agricultural machine can be established, because the transmission relation is arranged between the land wheel 1 and the main shaft of the discharger, the rotating speed of the main shaft of the discharger is directly related to the moving speed of the agricultural machine, and the transmission ratio of the land wheel 1 and the main shaft of the discharger is determined, so that how large the agricultural machine moves, the number of turns of the rotation of the main shaft of the discharger is determined, the land wheel and the discharger have good synchronism, and no matter how the, the materials spread by the material spreader are uniform all the time, and the difficulty in controlling the rotating speed of the main shaft of the discharger is greatly reduced.
As shown in fig. 1 and 4, the land wheel 1 includes an inner rim 12 with a hollow structure, and a plurality of anti-skid blades 11 are arranged on the outer circumference of the inner rim 12 in an array. Specifically, the anti-skid blades 11 are L-shaped, and have fixing portions welded to the inner ring 12 and anti-skid portions extending in the radial direction of the inner ring 12, the fixing portions of the anti-skid blades 11 are connected end to end and welded and fixed, and reinforcing ribs 14 are disposed between the fixing portions and the inner ring 12, so that the land wheel 1 is light in weight and stable and reliable in structure; when agricultural machine removed, the antiskid portion of each anti-skidding blade 11 embedded in turn makes land wheel 1 wholly roll in earth, and can not skid, has effectively guaranteed the relation between land wheel 1 pivoted angle displacement and agricultural machine's the removal displacement for the row's of material ware main shaft rotates accurately, and then guarantees the homogeneity that the material was scattered. The turning position of the anti-skid blades 11 is provided with the hollow holes 13, the arrangement of the hollow holes 13 can prevent soil from accumulating and caking at the turning position of the L-shaped anti-skid blades 11 to fill the gaps between the anti-skid parts of the two adjacent anti-skid blades 11, so that the anti-skid blades 11 lose the anti-skid effect, and after the hollow holes 13 are arranged, the soil can be timely discharged from the hollow holes 13.
Preferably, the ground wheel 1 establishes a transmission relationship with a main shaft of the discharger through a flexible shaft 3. The input end of the flexible shaft 3 establishes a transmission relation with the rotating shaft of the land wheel 1 through the bevel gear set 4, and the output end of the flexible shaft 3 is connected with a main shaft of a discharger (not shown in the drawing). Because the transmission distance between the land wheel 1 and the main shaft of the discharger is far, the transition structure between the land wheel 1 and the main shaft of the discharger is complex, the relative position relation between the land wheel 1 and the main shaft of the discharger is not definite, the transmission structure between the land wheel 1 and the main shaft of the discharger can be greatly simplified by arranging the flexible shaft 3, and the cost is saved. In addition, the output end of the flexible shaft 3 can output power to a plurality of groups of discharging devices, for example, an agricultural machine is provided with the discharging device for seed distribution and the discharging device for fertilizer distribution, and can simultaneously perform seed scattering and fertilization operations, in this case, the flexible shaft 3 can be directly connected with the main shaft of one discharging device, and the power can be synchronously supplied to the main shaft of one discharging device through a chain 5 or a synchronous belt.

The transmission mechanism 24 includes a first rod portion 241, a second rod portion 242, and a third rod portion 243, which form a four-bar linkage with the frame connecting seat 22, wherein the first rod portion 241 and the third rod portion 243 are both side links; the gear lever 23 is fixed on the first lever part 241, and the third lever part 243 is connected with the ground wheel frame 21; through the four-bar linkage structure, when the gear lever 23 is toggled back and forth, the land wheel frame 21 can be lifted up or put down, so that the land wheel 1 is switched; and when the land wheel 1 is in a use state, the first rod part 241 and the second rod part 242 are collinear, and the four-bar linkage structure is at a dead point, so that the design can effectively prevent the gear lever 23 from being separated from the current gear due to the mechanical impact between the land wheel 1 and the ground or other mechanical impacts are overlarge, so that the land wheel 1 cannot firmly grab the ground or is separated from the ground, and the discharging of the discharger is uneven.
Preferably, in order to maintain the effective contact between the land wheel 1 and the ground at all times, a pressure structure is provided between the third rod part 243 and the land wheel frame 21, and the pressure structure can make the land wheel 1 always maintain the contact with the ground. Specifically, as shown in fig. 3, the pressure structure includes a first rotating shaft 25 and a second rotating shaft 26, which are rotatably mounted on the wheel frame 21 and the third rod portion 243, respectively; the first rotating shaft 25 is connected with an adjusting seat 27, and the second rotating shaft 26 is slidably provided with an adjusting screw 28; the head of the adjusting screw 28 is screwed into the adjusting seat 27, and a first spring 29 is disposed between the adjusting seat 27 and the second rotating shaft 26.
Through the structure, the first spring 29 can play a role in maintaining the contact between the land wheel 1 and the ground, and when the land wheel 1 is subjected to larger reaction force or mechanical impact, the first spring 29 also plays a role in buffering and absorbing shock, so that the land wheel 1 can be effectively protected from deformation. In addition, the elevation angle of the land wheel frame 21 can be adjusted by rotating the adjusting screw 28, so that the anti-skid blades 11 of the land wheel 1 have different ground penetration depths, the land wheel 1 can adapt to different grounds, when the land wheel frame 21 is pressed down as much as possible when the land wheel is used in a paddy field, the ground penetration depth of the land wheel 1 is as deep as possible to ensure no skid, and when the land wheel frame 21 is used in a muddy field, the land wheel frame 21 can be properly lifted.
In order to facilitate the gear lever 23 to be retained at the gear position, the frame connecting seat 22 is provided with a sliding groove 221 (shown in fig. 2) for the gear lever 23 to move therein, and two ends of the sliding groove 221 are respectively provided with a retaining groove 222 (shown in fig. 5) for the gear lever 23 to be inserted into. A second spring 210 is disposed between the shift lever 23 and the rack connecting seat 22, and the second spring 210 can provide a pulling force to maintain the shift lever 23 in the retaining groove 222 where the shift lever is located, so that the shift lever 23 cannot be accidentally disengaged. When the gear position needs to be switched, the user only needs to disengage the gear position lever 23 from the current retaining groove 222 and twist the gear position lever 23 to move along the sliding groove 221 to the other end of the sliding groove 221 and insert the gear position lever into the retaining groove 222 at the other end.
