Mechanical connecting rod mechanism

Abstract

The invention belongs to the technical field of mechanical connecting rods, and particularly relates to a mechanical connecting rod mechanism. The mechanical connecting rod mechanism comprises a rotating connecting rod mechanism, a first connecting rod adjusting mechanism and a connecting rod transmission track combination. The rotating connecting rod mechanism comprises a rotating assembly arranged on a first connecting rod support and used for driving the connecting rod transmission track combination to rotate. The first connecting rod adjusting mechanism comprises a second connecting rod support rotationally connected with the first connecting rod support, a sliding assembly is fixedly connected with a first handle combination and rotationally connected with the first connecting rod support, and a sliding rail assembly is arranged on the second connecting rod support. The connecting rod transmission track combination comprises a plurality of track assemblies and a plurality of output end mounting assemblies, and the track assemblies and the output end mounting assemblies are annularly connected. Therefore, a first handle is in transmission connection with the output end, the first handle is adjusted to change the change of the transmission length of the output end, and the purpose of accurately adjusting the extension length of the output end is achieved.

Description

technical field [0001] The invention belongs to the technical field of seeders, and in particular relates to a mechanical linkage mechanism. Background technique [0002] Currently known seeding machines, such as corn planters, peanut planters, garlic planters, etc., in order to achieve single-grain seeding, often adopt the principles of spoon wheel type, air suction type, etc., but the above two seeding principles need to be matched. Corresponding accessories, such as spoon wheel seed meter, fan, etc. [0003] However, in the prior art, the joint work of the whole set of sowing machinery has not been realized through the mechanical linkage mechanism on the above-mentioned machinery, and most of the auxiliary devices in the prior art lead to the large size of the sowing machine, high cost, and inconvenient maintenance. It is difficult to apply to small and medium-sized seeders. The existing small and medium-sized seeders have not realized the drive of the seed scoop through...

Problems solved by technology

[0002] Currently known seeding machines, such as corn planters, peanut planters, garlic planters, etc., in order to achieve single-grain seeding, often adopt the principles of spoon wheel type, air suction type, etc., but the above two seeding principles need to be matched. Corresponding accessories, such as spoon wheel seed meter, fan, etc.

[0003] However, in the prior art, the joint work of the whole set of sowing machinery has not been realized through the mechanical linkage mechanism on the above-mentioned machinery, and most of the auxiliary devices in the prior art lead to the large size of the sowing machine, high cost, and inconvenient maintenance. It is difficult to apply to small and medium-sized seeders. The existing small and medium-sized seeders have not realized the drive of the seed scoop through the mechanical linkage mechanism to control the extension length of the seed scoop, so as to accurately adjust the sowing quantity of the sowing machine

[0004] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
