Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] Such as Figure 1-Figure 3 As shown, the structure of the no-tillage anti-blocking device of the rotary claw pressing type is as follows: the anti-blocking drive shaft 7 is installed on the frame 1 through the bearing, the first-stage power transmission gear 12 and the first-stage power distribution gear 9 mesh with each other, and the row drive The shaft 6 is assembled on the anti-blocking drive shaft 7 through the first-stage power transmission gear 12 and the first-stage power distribution gear 9, and the height of the row drive shaft 6 is 200-250mm. Its end is equipped with a pair of II-level power transmission gears 8 (the two bevel gears are mounted on the large end faces), and the II-level power transmission gears 8 and the final-stage gear 11 mesh with each other. The gear 8 is assembled on the row drive shaft 6, and the number of finger working groups ...

Abstract

The invention discloses a rotational claw pressed no-tillage anti-blockage device and belongs to the technical field of agricultural machinery. The device is structurally characterized in that an anti-blockage drive shaft is arranged on a rack through a bearing; an I-level power transmission gear and an I-level power distribution gear are mutually meshed; a traveling drive shaft is assembled on the anti-blockage drive shaft through the I-level power transmission gear and the I-level power distribution gear; the tail end of the traveling drive shaft is provided with a pair of II-level power transmission gears which are mutually meshed with an ultimate gear; poking working groups are assembled on the traveling drive shaft through the ultimate gear and the II-level power transmission gears; and an opener is arranged at a position no larger than 5cm away from the middle point of the connection line of the two adjacent poking working groups. The anti-blockage device provided by the invention has the beneficial effects of effectively reducing the operation amount, and being especially suitable for yield two crops a year of more moisture content of straws.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a no-tillage anti-blocking device of a counter-rotating claw pressing type. technical background [0002] Conservation tillage technology has been widely promoted in two-crop areas in my country. Due to the short harvest and sowing time in this area, the previous crops have high moisture and strong toughness, so they are not easy to be cut off. At present, the anti-blocking devices commonly used in this area mostly use the power stubble cutting type for anti-blocking and stubble cutting operations. Among them, the main power stubble cutting anti-blocking devices include strip crushing anti-blocking devices, belt-shaped rotary tillage anti-blocking devices, sawtooth anti-blocking devices, saw blade anti-blocking devices, driving notch disc-type anti-blocking devices and cutting and digging knives. Type anti-blocking device, etc. These anti-blocking de...
