Abstract

The invention discloses a seeder with advancing and seeding noninterference and smoother clutch, comprising an output shaft chain wheel, a land wheel chain wheel, a speed changer chain wheel group, a seeding wheel chain wheel and a chain, wherein the output shaft chain wheel is linked with a first chain wheel in the speed changer chain wheel group, a second chain wheel in the speed changer chain wheel group is linked with the land wheel chain wheel, a clutch chain wheel arranged on a clutch is linked with the seeding wheel chain wheel, and the clutch is coaxially and movably matched with a speed changer. A speed reducer divides power into two paths and transmits the power to the land wheel chain wheel and the seeding wheel chain wheel, intermediate transmission links are reduced, and the transmission resistance is reduced; the clutch is modified on the speed changer, and the clutch is arranged in the upper level of the seeding wheel in transitive relation, therefore, when the clutch acts, the impact suffered by the seeding wheel is reduced, and the seeding operation and the seeder walking can more smoothly clutch.

Description

technical field

[0001] The invention relates to an agricultural seeder. Background technique

[0002] The power transmission of common seeders adopts a step-by-step transmission process, that is, the output shaft of the engine is first linked to the transmission, the transmission is linked to the ground wheel, and the ground wheel is linked to the sowing wheel. There is sowing and walking synchronous work in this planter, and walking and sowing must be carried out simultaneously, stop walking sowing and just can't carry out, therefore, sowing will be restricted by walking action, can not make sowing operation and walking separation. Often, it is often encountered that the planter is driven into the ground, but at this time there is no need for sowing, and the method of not putting seeds in the seed box can only be taken temporarily, and the seeds are poured into the seed box when the seeds are to be planted. In order to solve the problem that this type of planter can only w...

Embodiment Construction

[0008] figure 1 Shown, the present invention comprises output shaft sprocket 2, ground wheel sprocket 9, speed changer sprocket set, planting wheel sprocket 7, clutch sprocket 5 and chain. The output shaft sprocket 2 is linked with the first sprocket 3 in the transmission sprocket set through the first chain 1, and the second sprocket 4 in the transmission sprocket set is linked with the ground wheel sprocket 9 through the second chain 8. The clutch sprocket 5 on the clutch is linked by the 3rd chain 6 and the sowing wheel sprocket 7. The clutch and the speed changer are installed on the same shaft, and the clutch and the speed changer are movably matched. The clutch that the present invention adopts is the patent product that I applied for earlier, and the patent number is ZL200720102525.1. During work, operate clutch, sowing wheel sprocket 7 is separated with speed changer, and this moment, planter advances by ground wheel, and sowing work stops. When the planter advances...
