In the related art, an adjusting and fixing mechanism is used to attach a land roller to a transplanting portion of a rice transplanter. Specifically, the adjusting and fixing mechanism may include an adjusting rod 1 and a supporting frame. Wherein, adjust pole 1 and connect on the plain ground roller, the support frame setting is on the frame main part of transplanting rice seedlings portion, and the support frame includes two at least support arms 2 that set up side by side, for example can be two support arms 2, or three support arm 3, or more.

The supporting arms 2 are provided with through holes, the adjusting rods 1 are inserted into the through holes of the supporting arms 2, for example, when the supporting arms 2 are two, the adjusting rods 1 sequentially penetrate through the through holes of the two supporting arms 2, and the land leveling roller is fixedly connected with the frame main body. This connection is inconvenient for the mounting and dismounting of the adjusting rod 1, and thus, is inconvenient for the mounting and dismounting of the flat ground roller.

In order to solve the above problem, referring to fig. 1 and 2, in the adjusting and fixing mechanism of the present embodiment, the hole wall of the through hole on the support arm 2 extends toward the upper edge of the support arm 2, and finally a notch is formed at the edge, so that the through hole of the support arm 2 is formed into a through groove structure, that is, the through groove structure is formed into the fixing groove 23, so that the adjusting rod 1 can pass in and out of the fixing groove 23 from the notch, and does not need to pass in and out of the fixing groove 23 in an inserting manner, thereby facilitating the disassembly and assembly of the adjusting rod 1. Here, the direction of the notch of the fixing groove 23 is referred to as a first direction in the present embodiment, that is, the first direction can be regarded as a direction in which the through hole extends toward the upper edge of the support arm 2, that is, a direction marked in fig. 3.

During the operation of the ground leveling roller, the support arm 2 applies a driving force to the ground leveling roller through the adjustment lever 1 such that the ground leveling roller has a tendency to press down the ground and to move forward, i.e., to move toward the direction b as indicated in fig. 3. The direction of the reaction force of the flat roller returned to the support arm 2 by the adjusting lever 1 is the obliquely upward direction, so that the adjusting lever 1 has a tendency to move obliquely upward relative to the fixing groove 23, and the adjusting lever 1 has a tendency to be disengaged from the fixing groove 23.

Therefore, referring to fig. 2, the fixing member 3 may be disposed on the support arm 2, and the fixing member 3 may be detachably connected to the support arm 2, so that when the fixing member 3 is connected to the support arm 2, the fixing member 3 can limit the movement of the adjustment rod 1 in the fixing groove 23 along the first direction, thereby preventing the adjustment rod 1 from being removed from the fixing groove 23 during the operation of the leveling roller.

Specifically, a mounting hole may be formed in the support arm 2, a fixing hole 32 is formed in the fixing member 3 at a position corresponding to the mounting hole, the fixing bolt 4 penetrates through the mounting hole and the fixing hole 32, and the support arm 2 is connected to the fixing member 3 by screwing a fixing nut 34 into the fixing bolt 4.

As an example, referring to fig. 5, the fixing member 3 may be a fixing plate of a plate-shaped structure having a shape corresponding to the support arm 2. When the fixing plate is installed on the support arm 2, specifically, at a position corresponding to the fixing groove 23 on the support arm 2, and at least partially covers the notch of the fixing groove 23, one side of the fixing plate facing the support arm 2 is closely attached to the support arm 2. At this time, the fixing plate functions to restrict the movement of the adjustment lever 1 in the first direction, thereby preventing the adjustment lever 1 from being released from the fixing groove 23.

As another embodiment, the fixing member 3 may be slidably disposed on the supporting arm 2, so that the limiting wall 31 of the fixing member 3 can at least partially cover the notch of the fixing groove 23 to prevent the adjusting lever 1 from being released from the fixing groove 23 or at least partially expose the notch of the fixing groove 23 to facilitate the releasing of the adjusting lever 1 from the fixing groove 23 during the sliding of the fixing member 3 relative to the supporting arm 2.

For example, a slide block may be disposed on a side surface of the fixing member 3 facing the support arm 2, and a sliding groove may be formed in the support arm 2; or a sliding groove is formed in the side face, facing the support arm 2, of the fixing part 3, a convex block or convex strip-shaped sliding block is arranged on the support arm 2, and the fixing part 3 slides relative to the support arm 2 through the matching of the sliding block and the sliding groove.

For another example, referring to fig. 6, the fixing member 3 may include a ring-shaped sliding portion provided to surround the support arm 2, and a stopper wall 31 provided on the sliding portion; the fixing member 3 is slidably disposed on the support arm 2 through a sliding portion, and when the fixing member 3 slides relative to the support arm 2, the limiting wall 31 on the sliding portion can cover/expose the notch of the fixing groove 23.

As a further optimization of this embodiment, the shape and size of the restricting wall 31 may correspond to those of the notches of the fixing groove 23, and the shape and size of the notches of the fixing groove 23 may correspond to those of the adjustment lever 1, so that the adjustment lever 1 may be escaped from the fixing groove 23 only after the restricting wall 31 slides to completely expose the notches of the fixing groove 23, thereby improving the stability of the connection of the adjustment lever 1 with the support arm 2.

In addition, referring to fig. 4, the fixing member 3 may also be a sleeve structure, and the fixing member 3 is sleeved on the support arm 2 and can slide relative to the support arm 2. At this time, a side wall of the holder 3 corresponding to the notch of the fixing groove 23 serves as a stopper wall 31, i.e., an upper side wall of the holder 3 shown in fig. 4.

In order to make the limit wall 31 of the fixing member 3 completely cover the notch of the fixing groove 23 and prevent the fixing member 3 from being interfered by the adjusting rod 1 during the sliding process, a clamping groove 33 may be formed on the sleeve structure, and the shape and size of the clamping groove 33 correspond to those of the adjusting rod 1. Therefore, after the limiting wall 31 covers the notch of the fixing groove 23, when the fixing member 3 is driven to slide relative to the support arm 2, the clamping groove 33 can be matched with the fixing groove 23 to clamp the adjusting rod 1, and the connection strength and stability of the adjusting and fixing mechanism of the embodiment are further improved.

As described above, since the adjustment lever 1 tends to move diagonally upward with respect to the fixing groove 23, the adjustment lever 1 tends to press against the stopper wall 31 of the fixing member 3 when the adjustment lever 1 is prevented from being removed in such a manner that the stopper wall 31 of the fixing member 3 covers the notch of the fixing groove 23. Therefore, in order to prevent the deformation of the position-limiting wall 31 of the fixture 3 during the pressing process by the adjustment rod 1, the notch direction of the fixing groove 23 according to the present embodiment is set at a specific angle, so that the adjustment rod 1 can contact the groove wall of the fixing groove 23 during the operation of the leveling roller and share the stress of the position-limiting wall 31. Specifically, referring to fig. 3, the notches of the fixing groove 23 are arranged along a first direction, and an included angle formed between the first direction and the advancing direction of the floor roll is an acute angle, that is, an included angle formed between the first direction and the second direction is an acute angle.

When the included angle between the first direction and the second direction is an acute angle, in order to increase the contact area between the adjusting rod 1 and the fixing groove 23, after the adjusting rod 1 abuts against the groove wall and the limiting wall 31 of the fixing groove 23, the adjusting rod 1 also contacts with the groove bottom of the fixing groove 23, and the limiting wall 31 and the groove bottom of the fixing groove 23 are matched to tightly clamp the adjusting rod 1 at least in the first direction. At this time, the smaller the angle between the first direction and the second direction is, the longer the notch of the fixing groove 23 in the second direction is, and the longer the fixing groove 23 as a whole in the second direction is, the lower the strength of the support arm 2 as a whole is. As a further optimization, the angle range of the included angle between the first direction and the second direction can be controlled within the range of 45 ° to 90 °, such as 60 °, 70 °, 75 °, 80 °.
