Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and more particularly to an active anti-blocking device for a single-drive double-action seed drill. Background Art

[0002] At present, in modern agricultural farming methods, the stubble cleaning process is particularly important. The effect of stubble cleaning is related to the quality of the seedbed and the emergence rate in the later stage, and even affects the yield of crops. However, there are still some problems in the use of existing stubble cleaning mechanisms, which is not conducive to promotion and application. For example: the current stubble cleaning mechanism is a passive anti-congestion device, which is prone to congestion when operating at high speed and with a large amount of straw, which is not conducive to the normal operation of the stubble cleaning mechanism, and there are problems such as poor straw cleaning effect. The current problems of the stubble cleaning mechanism will greatly affect the operating speed and sowing quality of the seeder, causing direct economic losses to farmers.

[0013] Preferably, the straw cleaning disc is arranged outside the gathered end of the bracket, and the straw cleaning disc is parallel to the gathered end of the bracket. The gathered end of the bracket is close to the middle, so that the straw cleaning disc is better moved to the middle.

[0014] Preferably, the straw cleaning disc is connected to the bracket via a mounting shaft, and the mounting shaft is rotatably connected to the bracket. Through the mounting shaft connection, the straw cleaning disc and the gathered end of the bracket can be kept parallel, thereby ensuring stable rotation of the straw cleaning disc.

[0015] Preferably, the transmission assembly includes: a first sprocket, a second sprocket, and a chain; the first sprocket is connected to the mounting shaft, the second sprocket is connected to the output shaft of the motor, and the chain is sleeved on the outside of the first sprocket and the second sprocket.
