The specific implementation mode is as follows:

the utility model is further illustrated below with reference to specific embodiments and the accompanying drawings.

The utility model relates to a dragging and overturning device of an agricultural cultivator, which is shown in figures 1 to 5 and is an embodiment of the utility model used for an agricultural rotary cultivator. The towing inverting device is located between the tractor 1 and the tilling device 2.

The tractor 1 is usually a crawler, which can drive a crawler driving wheel to run by a traction motor.

The cultivating device 2 of the first embodiment is an agricultural rotary tillage device. The farming device 2 includes: a base 21, a tilling member 22 mounted on the base 21, and a tilling motor 23 for driving the tilling member 22 to operate. The plowing motor 23 drives the plowing piece 22 to rotate, so that plowing of the land is achieved.

The cultivating device 2 is movably connected to the traction locomotive 1 through a dragging and overturning device. The dragging and overturning device comprises: a roll-over stand 3 pivoted on the traction locomotive 1, a fixed mount 4 fixed on the cultivating device 2, a linkage rod 5 connected between the roll-over stand 3 and the fixed mount 4, and a driving piece 6 mounted on the traction locomotive 1 and pivoted with the roll-over stand 3. As shown in figure 1, when the tractor 1 runs, the cultivation device 2 is movably connected with the tractor 1 through the dragging and overturning device, and when the tractor 1 runs, the cultivation device 2 is driven to run through the dragging and overturning device, so that the cultivation operation is realized. After the cultivation is finished, the dragging and overturning device pushes the overturning frame 3 to rotate through the driving piece 6, and pulls the fixing frame 4 and the cultivation device 2 to rotate, so that the cultivation device 2 and the supporting mechanism 8 are separated from the bottom surface, and suspension is realized. At this time, the traction engine 1 can directly bear the cultivation device 2 to run, and the cultivation device 2 does not need to be carried by other motor vehicles. When in use, a user can directly move the whole farming machine to a designated position through the traction locomotive 1, and then put down the farming device through the utility model to carry out farming operation.

The following is a preferred embodiment of the towing reversing device in this embodiment, and in this embodiment, the reversing frame 3 includes: a main roll-over stand bar 31, a longitudinal roll-over stand bar 32, a roll-over stand suspension bar 33 and a roll-over sub-stand 34. Wherein the main rod 31 of the roll-over stand is transversely arranged, and the two longitudinal rods 32 of the roll-over stand are longitudinally arranged above the main rod 31 of the roll-over stand. A roll-stand suspension bar 33 is located at the upper end of each roll-stand longitudinal bar 32 and extends towards the growing apparatus 2. The roll-over sub-frame 34 is located below the roll-over main frame 31. The fixing frame 4 comprises: a fixed support bar 41 and a fixed cross bar 42 supported by the fixed support bar 41. The fixing frame 4 may be provided independently and then fixed to the base 21 of the farming device 2 by welding, or may be integrally formed directly on the base 21.

The trace 5 pass through slipknot structure 50 swing joint between roll-over stand 3 and mount 4, and this trace 5 includes: an upper trace 51 located above and a lower trace 52 located below.

To ensure balance during towing, the upper trace 51 and the lower trace 52 may be distributed as follows: the trace 5 includes: two upper linkage bars 51 symmetrically distributed and two lower linkage bars 52 symmetrically distributed. The two upper linkage rods 51 symmetrically distributed are in a shape of a Chinese character 'ba', the two lower linkage rods 52 symmetrically distributed are in a shape of a Chinese character 'ba', and the upper linkage rods 51 and the lower linkage rods 52 are distributed in an opposite shape. I.e. on the roll-over stand 3: the slipknot structure 50 used for connecting one ends of the two upper linking rods 51 is positioned at the outer side positions of the two sides of the main rod 31 of the roll-over stand; the slipknot structure 50 used for connecting one end of the two lower linking rods 52 is positioned on the roll-over stand sub-frame 34, and the distance between the two slipknot structures 50 positioned on the roll-over stand sub-frame 34 is smaller than the distance between the two slipknot structures 50 positioned on the roll-over stand main rod 31. On the fixed bracket 4, a slipknot structure 50 for connecting the other ends of the two upper linkage rods 51 is positioned near the middle area of the fixed cross rod 42; the slipknot structure 50 for connecting the other ends of the two lower linkage bars 52 can be directly fixed on the base 21 of the cultivation device, and the distance between the two slipknot structures 50 on the fixed cross bar 42 is smaller than the distance between the two slipknot structures 50 on the base 21. Of course, the upper trace 51 and the lower trace 52 may be distributed in the opposite manner.

The slipknot structure 50 can adopt a ball head connection mode, an axle hole connection mode, a universal joint connection mode or other slipknot connection modes, so that the direction of the cultivating device 2 can be automatically adjusted in the running process, the two sides are balanced, and meanwhile, the whole cultivating device 2 can be limited to a certain extent by being matched with the traction of the upper linkage rod 51 and the lower linkage rod 52, and the deviation amplitude of the cultivating device 2 is not too large.

In addition, the tilling device 2 is not normally able to travel on roads. The tilling device 2 therefore needs to be stowed during periods of non-tilling in order to ensure that the utility model can be driven normally on the road. At this time, the cultivating device 2 can be rotated by the dragging and overturning device, so that the cultivating device 2 leaves the ground. As shown in fig. 2, the driving member 6 in this embodiment has a pushing function, and can directly turn the support 3, so as to drive the fixing frame 4 and the cultivating device 2 to rotate, thereby moving the whole cultivating device 2 away from the ground. The driving piece 6 can adopt a hydraulic piston piece, and can also adopt any one of a screw rod, a pneumatic piston assembly, an electric driving chain transmission mechanism and a steel wire winding mechanism.

The driving piece 6 is positioned below the pivoting part between the traction locomotive 1 and the roll-over stand 3, so that when the driving piece 6 works, the stroke distance is short, and the whole length does not need to be too long.

Because the roll-over stand 3 and the fixed mount 4 are movably connected through the linkage rod 5, when the driving member 6 directly drives and pushes the roll-over stand 3 to rotate, if the linkage rod 5 directly bears the force to drive the roll-over stand 3 to rotate, the slipknot structure 50 at the two ends of the linkage rod 5 may be forced to fall off or damaged, so the preferred mode is driven through a traction chain 7. The drag chain 7 is located between the roll-over stand 3 and the stationary stand 4 and remains suitably redundant. When the roll-over stand 3 rotates, in the initial stage, because the linkage rod 5 exists, the fixed mount 4 can not be directly driven to rotate, the traction chain 7 is tensioned along with the continuous rotation of the roll-over stand 3, and then the fixed mount 4 is pulled to start to rotate along with the roll-over stand 3 until the whole cultivation device 2 is separated from the ground, so that suspension is realized.

In order to increase the moment and reduce the force, the pulling force on the drag chain 7 is preferably distributed directly in the tangential direction of the rotation of the fixed frame 4, so in this embodiment one end of the drag chain 7 can be fixed directly at the end of the roll-over stand suspension rod 33. Because the roll-over stand suspension rod 33 extends towards the direction of the fixed mount 4, the distance between the tail end of the roll-over stand suspension rod 33 and the fixed mount 4 is shorter, the drag chain 7 is fixed at the tail end of the roll-over stand suspension rod 33, the length of the drag chain 7 can be effectively shortened, and the pulling force of the drag chain is matched with the tangential direction of the rotation of the fixed mount 4 as much as possible, thereby reducing the stress.

The drag chain 7 of the present invention may be a drag wire or a rope.

In the case where the cultivating apparatus 2 of the present embodiment is a tiller, the rotor 22 is a blade shaft. When the root-turning machine works, the ploughing depth of the root-turning machine can be gradually downward along with the operation of the cutter shaft. Therefore, in order to ensure that the depth of the ground plowed by the rotary tillage members 22 is consistent, the support mechanism 8 needs to be arranged. As shown in fig. 1, 2, and 3, a support mechanism 8 is further disposed near one end of the traction vehicle 1, and the support mechanism 8 includes: two supporting arms 81 with adjustable height and a supporting plate 82 fixed at the lower ends of the two supporting arms 81; the support plate 82 is tilted upward toward the traction vehicle 1, and its lower surface is a flat surface or a curved surface. Due to the existence of the supporting plate 82, the contact surface with the ground is larger, so the pressure to the ground is smaller, the whole cultivating device 2 can not gradually go deep into the ground, and the depth of the ploughed ground is kept consistent. The dragging and overturning device pushes the overturning frame 3 to rotate through the driving piece 6, and after the fixed frame 4 and the cultivation device 2 are pulled to rotate, the cultivation device 2 and the supporting mechanism 8 are separated from the bottom surface, so that suspension is realized.

The height adjusting mode of the supporting mechanism 8 is as follows: a sleeve 83 is fixed on the cultivating device 2, the supporting arm 81 is inserted in the sleeve 83, the supporting arm 81 is fixed in the sleeve 83 through a pin, and a plurality of positioning holes 810 matched with the pin are arranged on the supporting arm 81. Thus, the height of the supporting arm 81 can be adjusted by the pin matching with the positioning holes 810 with different heights. By adjusting the height of the support arm 81, the tilling depth of the tilling device 2 can be adjusted. Of course, the height adjustment can also be realized by adopting a screw structure.

The utility model can be applied to agricultural machinery which needs power drive for the cultivation device, such as: rotary cultivators, harvesters, cutters, and the like. As shown in fig. 6, this is an embodiment two of the present invention. The cultivation apparatus 2 of the second embodiment is a harvester, and the cultivation apparatus 2 of the harvester is operated by driving the screening mechanism 25 through the screen motor 24 to screen the crops with the plowshare 26 turned up.

It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention, which is defined by the appended claims.
