Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery and equipment, and particularly relates to an agricultural hybrid transmission Background Technique

[0002] With the development of technology, the existing farming methods have been transformed from traditional manual farming to mechanized production. Among them, the transformation of agricultural equipment is particularly obvious. Typical agricultural equipment includes micro-tillers, ridgers, seeders, and so on. For agricultural equipment, due to its limited terrain and poor working conditions, the requirements for agricultural equipment include large power demand, simplicity, reliability, and convenient maintenance.

[0003] Based on this, most of the power sources of agricultural equipment use diesel engines. When the diesel engine is actually running, in order to ensure sufficient power, surplus power will be provided, which will undoubtedly cause energy waste. In view of this situation, the hybrid power method can be used to solve the problem of energy waste, that is, the output end of the diesel engine is connected to a generator to convert the surplus energy into electric energy to reduce energy waste. However, the optimal efficiency of the generator is within a fixed range, and the rotational speed of the diesel engine itself is relatively low, making it difficult to maintain a high rotational speed and difficult to keep the generator in the optimal power generation range.

Detailed implementation manners

[0025] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 and Figure 2 shown:

[0027] An agricultural hybrid transmission includes a transmission body 1. The transmission body 1 is a transmission structure composed of a box body and a box cover, which will not be described in detail here. Among them, an input shaft 101, a first output shaft 102, and a second output shaft 103 are rotatably arranged in the transmission body 1, and the input shaft 101, the first output shaft 102, and the second output shaft 103 are all installed in the transmission body 1 through bearings, and the three bearings are parallel to each other.

[0028] During implementation, the left end of the input shaft 101 extends out of the transmission body 1 and is connected to the output end of the diesel engine 2. The power of the diesel engine is transmitted into the transmission body 1 through the input shaft 101 for distribution. Among them, a disc clutch 201 is provided at the output end of the diesel engine 2, and a release bearing 109 cooperating with the disc clutch 201 is provided at the left end of the input shaft 101. Through the setting of the disc clutch 201, the vibration at the connection between the output end of the diesel engine 2 and the input shaft 101 can be reduced, and the stability is better. Moreover, the size and mass of the disc clutch are relatively small, which is beneficial for weight reduction.

[0029] During implementation, a connecting pipe 110 is flange-connected between the transmission body 1 and the diesel engine 2. Bearings are provided on both sides of the connecting pipe 110. The input shaft 101 is installed in the connecting pipe 110 through the bearings. Through the setting of the connecting pipe 110, it can play a role in fixing and supporting the input shaft 101, reducing the wear of the bearings in the transmission body 1, and can also play a protective role for the input shaft 101, effectively improving the accuracy.

[0030] During implementation, a first transmission gear 104 and a first motor gear 105 are sequentially arranged on the part of the input shaft 101 in the transmission body 1 from left to right. The first transmission gear 104 is mainly used for power output, and the first motor gear 105 is mainly used for driving the generator 3. Specifically, a secondary shaft 111 is also provided in the transmission body 1, a second transmission gear 112 is provided on the secondary shaft 111, and a first driven gear 106 is provided on the first output shaft. The first transmission gear 104 meshes with the second transmission gear 112, and the second transmission gear 112 meshes with the first driven gear 106. Specifically, the pitch circle diameters of the first transmission gear 104, the second transmission gear 112, and the first driven gear 106 increase in sequence. The advantage of this is that through the setting of the pitch circle diameters of each gear, the speed of the input shaft 101 can be reduced and the power can be transmitted to the first output shaft 102 to achieve low-speed and high-torque output.

[0031] Specifically, a second motor gear 107 is provided on the second output shaft 103. The second motor gear 107 meshes with the first motor gear 105, and the pitch circle diameter of the second motor gear 107 is smaller than that of the first motor gear 105. Through this setting, the speed of the second output shaft 103 can be increased. During implementation, the right end of the second output shaft 103, that is, the output end 108, extends out from the right side of the transmission body 1 and is connected to the rotor of the generator 3. That is, after the speed of the second output shaft 103 is increased, it drives the rotor of the generator 3, so that the rotor of the generator 3 always remains in the optimal range.

[0032] During implementation, a fan blade �01 is connected to the end of the output end 108 of the second output shaft 103 through a coupling. The air outlet of the fan blade 301 corresponds to the generator 3. The fan blade 301 can dissipate heat from the generator 3. Among them, an installation housing 302 is also fixedly provided on the right side of the transmission body 1 through bolts. The installation housing 302 wraps the generator 3 as a whole, and a fan cover 303 is detachably provided at the right end of the installation housing 302 by screws, making it safer when the fan blade rotates.

[0033] During implementation, such as Figure 3, an oil guiding blind hole 113 is axially formed on the left side of the first output shaft 102. Specifically, an oil guiding through hole 114 is also radially formed on the left side of the first output shaft 102. Specifically, the oil guiding through hole 114 communicates with the oil guiding blind hole 113. There are multiple oil guiding through holes 114, which are evenly arranged on the first output shaft 102. The oil in the gearbox will enter the oil guiding blind hole 113, and then when the first output shaft 102 rotates, it will be thrown out through the oil guiding through holes 114 and enter the gear meshing position, reducing wear and having a longer service life. During implementation, a dial mounting wheel 115 is fixedly arranged on the first output shaft 102. An outer edge of the dial mounting wheel 115 is provided with a dial 116 through a connecting rod. A dial hole 117 is formed at the axial center position of the dial 116. The dial 116 will rotate with the first output shaft 102 and bring the gearbox oil to different positions of the gearbox. The setting of the dial hole 117 can effectively reduce the oil resistance during oil guiding, and the power loss is lower. During implementation, oil inlet holes 118 are also spacedly arranged in the circumferential direction of the dial mounting wheel 115. Through the setting of the oil inlet holes 118, the introduced gearbox oil can enter between the dial mounting wheel 115 and the first driven gear, and can also reach between the first driven gear 106 and the first output shaft 102, reducing the wear therebetween.

[0034] The principle of this solution is that when the diesel engine 2 is used as the power source of agricultural machinery and equipment, the power provided by the diesel engine 2 usually greatly exceeds the actual required power, and thus there is a situation of wasted redundant power. In this solution, the power is distributed through the input shaft 101 and each output shaft in the gearbox body 1. Then, a part of the redundant power is used to generate electricity for the generator 3, and the power is fully utilized, which is more environmentally friendly. When generating electricity, with the cooperation of the first motor gear 105 on the input shaft 101 and the second motor gear 107 on the second output shaft 103, the rotor of the generator 3 can be maintained at the optimal speed, and the power generation efficiency is better.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims.
