Detailed Description

As shown in fig. 1 to 4, a reverse rotation rolling type seeder capable of avoiding automatically comprises a roller 1, a rotating shaft 2, a duckbill 3, a deflector rod 4, a spring 5, a bracket 6 and an interlock 7; the roller 1 is installed on the rotating shaft 2 through a bearing, the number of the duckbilled pieces 3 is 12, the duckbilled pieces 3 are evenly distributed on the circumference of the roller 1, the number of the shift lever 4 is consistent with the number of the duckbilled pieces 3, one end of the shift lever 4 is connected with the duckbilled pieces 3, the other end of the shift lever is an angle bending rod with an angle of 120 degrees and extends to the upper side of the disc surface of the roller 1, the shift lever 4 is connected with the roller 1 through a spring 5, the support 6 comprises two vertical rods 6-1 and push rods 6-2, the number of the vertical rods 6-1 is two, the two vertical rods 6-1 are arranged in parallel, the top ends of the two vertical rods 6-1 are connected through the push rods; the interlocking 7 comprises a fixed disc 7-1, a movable disc 7-2 and toggle wheels 7-3, the fixed disc 7-1 is square, limit blocks are arranged on one group of diagonal corners, one end of the other group of diagonal corners is fixedly arranged on a vertical bar 6-1 of the support 6 through bolts, the other end of the diagonal corners is movably connected with one end of the movable disc 7-2, the other end of the movable disc 7-2 is provided with the toggle wheels 7-3, the outer circle surface of the toggle wheels 7-3 is sequentially and movably pressed and connected with one end of a dog-ear rod of each toggle rod 4, the number of the toggle wheels 7-3 is 2, the toggle wheels are arranged at the same end of the movable disc 7-2 side by side, the outer circle of the toggle wheel 7-3 is made of rubber, and the rubber; in addition, an observation window is arranged on the disc surface of the roller 1, and a hook is arranged on a push rod 6-2 of the bracket 6.

As shown in fig. 5 and 6, the working process of the reverse-rotation automatic-avoiding rolling-type seeder is that corn seeds are added into the roller 1, and the roller 1 is pushed to rotate by the push rod 6-2; when the roller 1 rotates forwards, the outer circle surface of a poking wheel 7-3 of the interlocking 7 is always in movable pressure connection with one end of each poking rod 4 above the disc surface of the roller 1, namely one end of each bevel rod, so as to drive the duckbill 3 to open and seed, and then the duckbill is restored to the initial closed state through the spring 5; specifically, as shown in fig. 5, when the roller 1 rotates in the forward direction, that is, clockwise, the movable disc 7-2 of the interlock 7 is driven to rotate clockwise around the fixed disc 7-1, and when the roller rotates to a certain angle, the roller is limited by the limiting block to be compacted on the fixed disc 7-1 and fixed, so that the toggle wheel 7-3 is always movably pressed and connected with one end of the bevel lever adjacent to the toggle lever 4; as shown in fig. 6, when the roller 1 rotates in the opposite direction, that is, counterclockwise, the movable disc 7-2 still rotates counterclockwise with the fixed disc 7-1 as the axis, and is locked by the limit block on the fixed disc 7-1 when rotating to a certain angle, because the end of the poking wheel 7-3 contacted with the poking wheel 4 is the bevel lever with the angle greater than 90 degrees, the poking wheel 7-3 is only contacted with the tail end of the poking wheel 4, the duckbill 3 can not be opened, the rotation of the roller 1 can not be influenced, and the roller 1 can reach the idle state without seeding; therefore, the rolling seeder can ensure that the roller 1 can positively rotate to sow, and automatically avoid the deflector rod and idle in reverse rotation, thereby reducing the influence of the reverse rotation of the roller on the machine.
