In the above technical scheme, the adjusting rod 121 is provided with a poking rod 123 which is horizontally arranged along the front-back direction and is fixedly connected with the adjusting rod 121 at one end, the middle of the other end of the poking rod 123 is concavely provided with a notch 1231 which is vertically communicated, the driving end of the adjusting piece 122 is provided with a vertically arranged poking shaft 1221, the poking shaft 1221 extends into the notch 1231, the adjusting piece 122 is used for driving the poking shaft 1221 to move left and right, the adjusting rod 121 is moved in two dimensions along the left-right direction and the front-back direction in the horizontal plane under the action of the poking shaft 1221 and the plurality of pin shafts 132, so that the adjusting piece drives the poking shaft to move left and right, the poking rod moves left and right under the action of the poking shaft and moves up in the front-back direction under the action of the guide holes and the pin shafts, and the poking shaft and the poking rod are movably connected at the moment, and the poking rod is favorable for moving up in the front-back direction while moving along with the left and right movement of the poking shaft.

The adjustment lever 121 constitutes the driving end of the adjustment assembly.

As shown in fig. 4, in the above technical solution, the side wall of the shifting shaft 1221 is provided with a ring groove 12211, the end of the notch 1231 of the shifting rod 123 extends into the ring groove 12211, the shifting shaft 1221 can be opposite to the shifting rod 123 moving along the front-back direction in the notch 1231, so that the shifting shaft and the shifting rod can be prevented from separating from each other, and the shifting shaft can be limited by the shifting rod.

As shown in fig. 4, in the above technical solution, the adjusting member 122 further includes a mounting seat 1222, a bolt 1223, a nut 1224, and a spring 1225, the mounting seat 1222 is n-shaped, a slot of the mounting seat 1222 faces downward and is mounted at the upper end of the cover plate body 11, an inner slot of the mounting seat 1222 is through front and back, holes aligned with each other are formed in both side arms of the mounting seat 1222, the dial shaft 1221 is located in the slot of the mounting seat 1222, a screw hole penetrating through left and right and threadedly engaged with the bolt 1223 is formed in the dial shaft 1221, the screw hole is aligned with the two holes, the bolt 1223 passes through the screw hole and the two holes, the bolt 1223 is threadedly connected with the screw hole, the nut 1224 is threadedly mounted at a threaded end of the bolt 1223, the spring 1225 is sleeved on the bolt 1223 and is located between the nut 1224 and the mounting seat, the elastic force of the spring 1225 is used to drive the head of the bolt 1223 to tend to abut against the mounting seat 1222, the bolt 1223 is rotated relative to move left and right, and left, the mounting seat is simply screwed on the mounting seat by the mounting seat 1221.

In the above technical solution, the upper end of the mounting seat 1222 is further provided with a serrated angle mark 12221 along the left-right direction, so that the inclination direction of the guide plate can be observed conveniently.

The depth of the notch is required to meet the requirement that the shifting shaft is always positioned in the notch when the adjusting rod moves forwards and backwards.

Because the interlock of poker rod breach is in the annular of poker shaft, so when rotating the bolt, the poker shaft can not rotate along with the bolt, and the two rotates relatively at this moment and can adjust the bolt head to the interval of poker shaft, and the spring makes the head of bolt offset with the mount pad all the time, so the poker shaft can for when rotating the bolt moves about the mount pad (in addition when rotating the bolt, the nut can rotate along with the bolt is synchronous), still makes the regulating part have certain buffer function through setting up the spring on the bolt, when straw or debris violent striking grass guide plate, but the grass guide plate can the impact effect swing in the twinkling of an eye down in order to play the cushioning effect (the space of buffering comes from the compression space of spring, can play the guard action to the grass guide plate like this).

In the embodiment, the adjusting assembly is arranged at the upper end of the cover plate body, so that the adjusting assembly does not influence the normal discharge of straws below the cover plate body (the problem that straws are hooked or wound on the adjusting assembly cannot occur), in addition, in the embodiment, the adjusting rod drives a plurality of grass guide plates to synchronously deflect by taking the guide hole as a track above the cover plate body, at the moment, the adjusting rod keeps horizontal in the left-right direction, but can generate displacement in the front-back direction on the cover plate body, and the poke rod is meshed (movably connected) with the poke shaft through a gap, so that the poke shaft provides a moving margin for the front-back displacement of the adjusting rod, and the poke shaft drives the adjusting rod to move left and right through the poke rod; in addition, the spring is further sleeved on the bolt of the adjusting piece, and the spring is located between the nut and the mounting seat (the spring has a buffering space), so that a certain avoiding space is provided for the grass guide plates, the grass guide plates can swing along with the bolts when encountering barriers or violent impacts to avoid bending deformation of the grass guide plates.

Example 2

As shown in fig. 6, the embodiment provides a straw apron subassembly is arranged to hood tail, include roof 2, tailboard 3 and like embodiment 1 lead straw apron 1, roof 2, apron body 11 and tailboard 3 all set up and distribute according to the order along the front and back direction along left right direction, and the three connects gradually and is a bent plate, just one side orientation that apron body 11 was equipped with and led straw board 13 the inboard of bent plate makes so that it is good to the direction effect of straw, and can carry out the equipartition to the straw.

In the above technical scheme, the included angle of the joint of the top plate 2 and the cover plate body 11 and the included angle of the joint of the cover plate body 11 and the tail plate 3 are obtuse angles, so that the straw can be still removed towards the rear lower side after being removed, and the included angle between the top plate and the tail plate is also an obtuse angle.

Example 3

This embodiment provides a harvester, includes the hood row grass apron subassembly as in embodiment 2, so this harvester can be when adding the straw cutter no matter this, all can lead and the equipartition to the straw.
