[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-4 As shown, the utility model provides a folding and limiting device for a paddy field slurry mixer, comprising a main machine 1;

[0028] A folding machine 2, which is rotatably connected to the main machine 1 via stoppers 3 on both sides;

[0029] At least one set of folding hydraulic cylinders 4, one end of which is rotatably connected to the folding tool 2, and the other end of which is rotatably connected to the main tool 1;

[0030] At least one group of folding hydraulic cylinders 4 is arranged according to factors such as the width and dead weight of the main machine 1 and the folding machine 2 of the pulper. The pulper shown in the utility model is equipped with a group of folding hydraulic cylinders 4. By setting a limiter 3, the stability of the folding machine 2 in switching between the working state and the non-working state is better guaranteed.

[0031] The limiting member 3 includes a fixed seat 31, a support frame 32, a folding block 33, an abutment block 34 and a limiting block 35. The fixed seat 31 is installed at both ends of the main machine 1, the support frame 32 is installed on the fixed seat 31, the folding block 33 is installed on the folding machine 2, and the lower end of the support frame 32 facing the folding machine 2 is hinged to the folding block 33. The fixed seat 31 is also equipped with an abutment block 34 that cooperates with the folding block 33 to limit the position after flipping;

[0032] The limit block 35 is installed at one end of the folding tool 2 facing the main tool 1, and abuts against the fixing seat 31 after being turned over;

[0033] When in the road transport state, the folding hydraulic cylinder 4 contracts, and the two folding tools 2 move toward the two ends of the main tool 1 respectively, until the folding blocks 33 respectively abut against the corresponding limit blocks 33, at which time the folding tools 2 are folded toward the main tool 1 to be in a vertical state;

[0034] When in operation, when the folding hydraulic cylinder 4 is extended, the two folding tools 2 are respectively unfolded toward the two ends of the main tool 1 until the limit block 35 abuts against the fixing seat 31. At this time, the main tool 1 and the folding tool 2 are unfolded in a horizontal state.

[0035] On the basis of the above embodiment, the support frame 32 is configured as a group of L-shaped plates, and the folding blocks 33 are installed between the L-shaped plates and are rotatably connected to the folding blocks 33 via pins.

[0036] On the basis of the above embodiment, the folding block 33 and the abutment block 34 are both provided with an inclined surface to form a pair of wedge-shaped parts. The folding block 33 and the abutment block 34 form a limiting surface by virtue of the fit between the two inclined surfaces. When the folding machine 2 is flipped over by the push of the folding hydraulic cylinder 4 to form the limiting surface, the fitting area between the main machine 1 and the folding machine 2 is significantly increased, thereby improving the reliability of the folding installation.

[0039] On the basis of the above embodiment, a threaded hole is opened on the corresponding folding machine 2 of the limit block 35, and the axial direction of the threaded hole is consistent with the movement direction of the limit block 35. The limit block 35 is fixedly matched with the folding machine 2 through the threaded hole, and the axial position can be appropriately adjusted by screwing the limit block 35 and the folding machine 2.

[0040] Specific working process:

[0041] Firstly, by extending or retracting the folding hydraulic cylinder 4, the main machine 1 drives the folding machine 2 to be folded upward or unfolded downward, thereby realizing the folding function of the pulp mixer. The limiting member 3 cooperates with the folding hydraulic cylinder 4 to limit the stability of the folding machine 2 in the working state and the non-working state, thereby avoiding the problem of the pulp mixer being damaged by shaking during road transportation and operation, and extending the service life of the pulp mixer.

[0042] The utility model discloses a folding limit device for a paddy field puddler, which is suitable for any folding agricultural machinery, including a rotary tiller, a seed drill, a transplanter, etc. By setting the limiter, the functions of limiting the relative position and the rotation stroke of the folding machinery can be realized, thereby playing a certain protective role on the folding machinery.
