Description

A mechanism for cleaning straw of a no-till seeder

technical field

The invention relates to a seeder technology, in particular to a straw cleaning mechanism for a no-tillage seeder.

Background technique

In order to adapt to the national policy of banning straw burning, the wheat straw after harvesting is basically crushed and returned to the field. If soybeans are planted, the crushed wheat straw will be pushed together by the two rows of openers of the planter due to the small ridge spacing of soybeans. Farmers have to remove the wheat stalks and transport them away, which is time-consuming and laborious, and loses the effect of returning the stalks to the field to increase soil fertility.

Contents of the invention

The problem to be solved by the present invention is that after the harvested wheat straw is crushed and returned to the field, it covers the soil surface. The existing ditching type seeder has a small ridge distance. When sowing soybeans, the wheat straw on the ground will be pushed into piles. affect seeding. Provided is a mechanism for cleaning wheat stalks of a no-tillage seeder. When sowing soybeans, the wheat stalks collected by a ditch opener can be pushed backward and discharged, and the ditch opener can be cleaned for normal sowing.

The technical solution of the present invention is realized in the following manner, a mechanism for cleaning straw of a no-tillage planter, comprising a sowing frame (1), a ditch opener (2), and ground wheels (3) mounted on the sowing frame (1 ), a cleaning straw frame (4) is installed under the seeding frame (1), and cleaning teeth (6) are installed under each longitudinal column (5) of the cleaning straw frame (4). The cleaning teeth (6) are erected The guide rod (7) and the skid plate (8) are composed of the guide rod (7) and the skid plate (8), the front end of the skid plate (8) of each cleaning tooth (6) is connected with the shaft pin (9) below the longitudinal column (5), and the rear end The guide rod (7) is inserted into the guide hole (10) of the longitudinal column (5), and can move up and down with the shaft pin (9) as the axis. The position of the longitudinal column (5) is between two adjacent openers (2 ), and on both sides of the sowing frame (1), install the axle seat (11), install the swing arm (12) on the axle seat (11), the upper end of the swing arm (12) and the axle seat (11) Shaft connection, the lower end is connected with the shaft of the cleaning straw frame (4), on both sides of the cleaning straw frame (4), connect with one end of the connecting rod (13) with the pivot pin (9), and the other end of the connecting rod (13) is connected with The shaft pin (9) is connected with the rocker arm (14), and the two ground wheels (3) rotate synchronously, and are installed on the same ground wheel shaft (15). When rotating, the ground wheel (3) and the ground wheel shaft (15) are relatively stationary .

Rocking arm (14) is installed on the ground wheel (3).

The beneficial effect of the invention is that soybeans can be sown smoothly in the farmland covered with wheat straw, and the planting mode of returning the straw to the field is promoted.

Detailed ways

In the embodiment shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a mechanism for clearing straw of a no-till seeder includes a sowing frame 1, a ditch opener 2, and ground wheels 3 installed on the sowing frame 1. Above, a cleaning straw frame 4 is installed below the seeding frame 1, and a cleaning tooth 6 is installed below each longitudinal column 5 of the cleaning straw frame 4. The cleaning tooth 6 is composed of an upright guide rod 7 and a skid plate 8, each The front end of the skid plate 8 that cleans the teeth 6 is connected below the longitudinal column 5 with the pivot pin 9, and the guide rod 7 at the rear end is inserted into the guide hole 10 of the longitudinal column 5, and can move up and down with the pivot pin 9 as the axis, and the longitudinal The position of column 5 is between two adjacent ditch openers 2, again on the both sides of sowing frame 1, axle seat 11 is installed, swing arm 12 is installed on axle seat 11, the upper end of swing arm 12 and axle seat 11 axis connection, the lower end is connected with the 4-axis cleaning straw rack, on both sides of the straw cleaning rack 4, the pivot pin 9 is connected with one end of the connecting rod 13, and the other end of the connecting rod 13 is connected with the rocker arm 14 through the pivot pin 9, The two ground wheels 3 rotate synchronously, and are installed on the same ground wheel shaft 15. When rotating, the ground wheels 3 and the ground wheel shaft 15 are relatively stationary.

Rocking arm 14 is installed on the ground wheel 3.

Working process: the no-tillage planter is pulled by the tractor, and the two ground wheels 3 roll on the ground to control the height of the no-tillage planter frame from the ground. When ditch opener 2 moves forward, the ground is opened about 60 millimeters deep ditch, and bury seed. Two shaft seats 11 lift the cleaning straw frame 4 below the planting frame 1 through two swing arms 12, and the rocking arm 14 installed on the ground wheel 3 drives the cleaning straw frame 4 to reciprocate back and forth through the connecting rod 13. The skid plate 8 of the cleaning tooth 6 that is installed in each longitudinal column 5 below, the front end takes pivot pin 9 as the center of circle, and the guide bar 7 that the rear end erects moves up and down in the guide hole 10. When the rocking arm 14 on the ground wheel 3 was rotated from back to front for the upper half, the connecting rod 13 drove the cleaning straw frame 4 to move forward, and also drove the skid plate 8 of the cleaning tooth 6 to slide forward on the ground, pressing the straw. When the rocker arm 14 on the ground wheel 3 rotates from front to back for the second half circle, the cleaning straw rack 4 is driven to move backward through the connecting rod 13, and the guide rod 7 of the cleaning tooth 6 is lowered in the guide hole 10 by gravity and moves backward. Move to the position beyond the ditch opener 2, and the wheat stalks pushed by the ditch opener 2 are discharged backward by the vertical guide rod 7, so that the normal sowing is maintained by reciprocating.
