Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to the field of agricultural machinery power, and specifically refers to an agricultural machinery transmission device. Background Art

[0002] As an indispensable mechanical equipment in agricultural production, agricultural machinery is widely used in various links such as crop planting, harvesting, and field management. When farmers cultivate in mountainous areas, terraced fields, or small cultivated land, they cannot use large agricultural equipment due to the influence of the terrain, so they often use small agricultural machinery to improve agricultural production efficiency.

[0003] Compared with plains and large cultivated land, due to objective factors such as narrow road space and difficulty in turning agricultural machinery in mountains, terraces or small cultivated land, in order to facilitate farmers' use, small agricultural machinery is required to be as compact as possible and as small as possible; at the same time, since most small agricultural machinery is operated in outdoor fields, the operating environment is complex, in order to avoid the increase in maintenance costs caused by frequent failures, higher requirements are placed on the reliability of small agricultural machinery. As an indispensable component of small agricultural machinery, the compactness and reliability of the transmission device will directly affect the applicability and durability of small agricultural machinery.

[0004] The transmission devices in the small agricultural machinery commonly found on the market currently have some problems in actual use. For example, the pulleys and belts used by the transmission device to transmit power to the walking mechanism and working mechanism of the small agricultural machinery are usually located outside the housing of the transmission device. Since they are directly exposed to the external environment, the belts and pulleys are easily affected by wind and sun and are prone to aging and breaking. At the same time, when working in cultivated land, paddy fields and other environments, the belts and pulleys are easily contaminated and damaged by sand, gravel, mud and water, further reducing the durability of the belts and pulleys. In addition, the housing of the transmission device of the existing small agricultural machinery is usually spliced ​​by multiple sections of the housing located on both sides of the transmission device. During the splicing process of the housing, it is very easy to accumulate assembly errors, resulting in a reduction in the assembly accuracy of the housing and the transmission components, so that the transmission device needs to overcome additional friction resistance when working, which leads to a reduction in the transmission efficiency of the transmission device, which undoubtedly reduces the working efficiency of the small agricultural machinery.

[0049] 1. Power input of power unit

[0050] The power of the power unit is transmitted to the clutch body 2101 through the power input shaft of the clutch body 2101. The clutch body 2101 can be controlled by the separator 2102 to transmit power to the power output shaft of the clutch or cut off the power transmission. If the rotation direction of the walking wheels and other walking parts is defined as forward rotation when the agricultural machinery moves forward, the power of the power unit is transmitted to the first rotating shaft 2201 through the first gear 2301 and the second gear 2302, driving the first rotating shaft 2201 and the third gear 2303 to rotate in the opposite direction, and driving the fourth gear 2304 and the second rotating shaft 2202 to rotate forward through the third gear 2303.

[0051] 2. Speed ​​gear control of agricultural machinery

[0052] Gear position 1: When the first shift fork 2403 shifts the fifth gear 2305, causing the fifth gear 2305 to slide along the axial direction of the second rotating shaft 2202 and causing the first meshing portion of the fifth gear 2305 to mesh with the fourteenth gear 2314, the fifth gear 2305 drives the fourteenth gear 2314 and the fourth rotating shaft 2204 to rotate in the opposite direction, and at the same time, the eleventh gear 2311 drives the seventh gear 2307 to rotate in the opposite direction through the sixth gear 2306, and the eighth gear 2308 drives the tenth gear 2310 and the sixth rotating shaft 2206 to rotate in the positive direction, and drives the traveling wheels and other traveling parts to rotate in the positive direction through the first power output assembly;

[0053] Gear position 2: When the first shift fork 2403 shifts the fifth gear 2305, causing the fifth gear 2305 to slide along the axial direction of the second rotating shaft 2202 and causing the second meshing portion of the fifth gear 2305 to mesh with the twelfth gear 2312, the fifth gear 2305 drives the twelfth gear 2312 and the fourth rotating shaft 2204 to rotate in the opposite direction, and at the same time, the eleventh gear 2311 drives the seventh gear 2307 to rotate in the opposite direction through the sixth gear 2306, and the eighth gear 2308 drives the tenth gear 2310 and the sixth rotating shaft 2206 to rotate in the positive direction, and drives the traveling wheels and other traveling parts to rotate in the positive direction through the first power output assembly;

[0054] Gear position three: when the first shift fork 2403 shifts the fifth gear 2305, so that the fifth gear 2305 slides along the axial direction of the second rotating shaft 2202 and the second meshing portion of the fifth gear 2305 meshes with the ninth gear 2309, the fifth gear 2305 drives the fourteenth gear 2314 and the fourth rotating shaft 2204 to rotate forwardly through the ninth gear 2309, and at the same time, the eleventh gear 2311 drives the seventh gear 2307 to rotate forwardly through the sixth gear 2306, and the eighth gear 2308 drives the tenth gear 2310 and the sixth rotating shaft 2206 to rotate in the opposite direction, and drives the traveling wheels and other traveling parts to rotate in the opposite direction through the first power output assembly. This is the reverse gear of the agricultural machine.

[0055] Gear position 4: When the first shift fork 2403 shifts the fifth gear 2305, so that the fifth gear 2305 slides along the axial direction of the second rotating shaft 2202 and the fifth gear 2305 is not meshed with any gear, the fifth gear 2305 idles, and the power of the power device will not continue to be transmitted to other rotating shafts. At this time, the agricultural machine is in neutral gear;

[0056] Since the diameter of the first meshing portion of the fifth gear 2305 is smaller than the diameter of the second meshing portion, and the diameter of the twelfth gear 2312 is smaller than the diameter of the fourteenth gear 2314, the speed ratio when the fifth gear 2305 is meshed with the twelfth gear 2312 is greater than the speed ratio when the fifth gear 2305 is meshed with the fourteenth gear 2314. At the same time, since the first power shaft 2501 is equipped with walking wheels and other components for walking, the first gear is the slow forward gear of the agricultural machinery, and the second gear is the fast forward gear of the agricultural machinery. When the second rotating shaft 2202 rotates forward, the position of the fifth gear 2305 is shifted by the first fork 2403, so that the agricultural machinery can switch between the slow forward gear, the fast forward gear, the reverse gear, and the neutral gear.

[0057] 3. Second power output assembly power transmission

[0058] Since the second power shaft 2601 is equipped with working parts such as a rotary tiller, the working parts can be rotated forward, reversed or stopped by controlling the rotation direction of the seventh rotating shaft 2207;

[0059] Working parts forward gear position: when the agricultural machine is in the slow forward gear or the fast forward gear, the fourth rotating shaft 2204 rotates in the reverse direction, and the thirteenth gear 2313 is moved by the second fork 2404, so that the thirteenth gear 2313 slides along the axial direction of the fourth rotating shaft 2204 and the thirteenth gear 2313 is meshed with the eighteenth gear 2318, and the thirteenth gear 2313 drives the eighteenth gear 2318 and the seventh rotating shaft 2207 to rotate forward, and drives the rotary blade and other working parts to rotate forward through the second power output assembly;

[0060] When the agricultural machine is in reverse gear, the fourth rotating shaft 2204 rotates forward, and the second fork 2404 shifts the thirteenth gear 2313, so that the thirteenth gear 2313 slides along the axial direction of the fourth rotating shaft 2204 and the thirteenth gear 2313 meshes with the fifteenth gear 2315, and the thirteenth gear 2313 drives the fifteenth gear 2315 and the fifth rotating shaft 2205 to rotate in the opposite direction, and at the same time, the sixteenth gear 2316 drives the seventeenth gear 2317 and the seventh rotating shaft 2207 to rotate forward, and drives the rotary blade and other working parts to rotate forward through the second power output assembly;

[0061] Working component reverse gear: when the agricultural machine is in the slow forward gear or the fast forward gear, the second fork 2404 shifts the thirteenth gear 2313, so that the thirteenth gear 2313 slides along the axial direction of the fourth rotating shaft 2204 and the thirteenth gear 2313 meshes with the fifteenth gear 2315, and the thirteenth gear 2313 drives the fifteenth gear 2315 and the fifth rotating shaft 2205 to rotate forwardly, while the sixteenth gear 2316 drives the seventeenth gear 2317 and the seventh rotating shaft 2207 to rotate in the reverse direction, and drives the rotary blade and other working components to rotate in the reverse direction through the second power output assembly;

[0062] When the agricultural machine is in reverse gear, the fourth rotating shaft 2204 rotates forward, and the second fork 2404 shifts the thirteenth gear 2313, so that the thirteenth gear 2313 slides along the axial direction of the fourth rotating shaft 2204 and the thirteenth gear 2313 meshes with the eighteenth gear 2318, and the thirteenth gear 2313 drives the eighteenth gear 2318 and the seventh rotating shaft 2207 to rotate in the opposite direction, and drives the rotary blade and other working parts to rotate in the opposite direction through the second power output assembly;

[0063] The working part stops rotating. When the thirteenth gear 2313 slides axially along the fourth rotating shaft 2204 to a position where it is not engaged with any gear, the thirteenth gear 2313 idles, and therefore power is not transmitted to the fifth rotating shaft 2205 and the seventh rotating shaft 2207, thereby causing the second power output assembly to lose power and the working part stops rotating.
