Detailed Description of the Embodiment

[0026] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanations of the present utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.

[0027] The following combines the attached drawings to describe the present utility model in detail. An overturning and lifting assembly of a deep tillage machine disclosed in this embodiment is as Figure 1As shown in the figure, it includes a tipping bracket 1. The tipping bracket 1 is hinged to the output end of a tipping oil cylinder 2 and the bottom end of a lifting oil cylinder 3. The lifting oil cylinder 3 is connected to the transfer case panel 4. A guiding column 5 is fixedly connected to the tipping bracket 1, and the transfer case panel 4 is slidably connected to the guiding column 5. A locking device 6 is further provided on the transfer case panel 4. The tipping bracket 1 is hinged to the vehicle frame, and the bottom end of the tipping oil cylinder 2 is hinged to the rear end of the vehicle frame.

[0028] In this embodiment, as Figure 2 shown, the tipping bracket 1 includes a bottom frame 11. At both ends of the portal beam 111 of the bottom frame 11, columns 112 are vertically fixed. The two columns 112 are symmetric with respect to the center line of the portal beam 111. Two first ear plates 113 are provided on the inner sides of the intersection positions of the portal beam 111 and the columns 112, and through holes are opened on the first ear plates 113.

[0029] In this embodiment, as Figure 1 shown, a second ear plate 31 is provided at the bottom end of the lifting oil cylinder 3, and a third ear plate 32 is provided at the output end. Through holes are opened on both the second ear plate 31 and the third ear plate 32. The second ear plate 31 is arranged between the two first ear plates 113 and then fixed by passing through a pin shaft to realize the hinged connection between the lifting oil cylinder 3 and the tipping bracket 1.

[0030] In this embodiment, as Figure 1 shown, two convex plates 41 are fixedly connected to the transfer case panel 4. The convex plates 41 are symmetrically arranged with respect to the center line of the transfer case panel 4. Two ninth ear plates 411 are provided on the convex plates 41, and through holes are opened on the ninth ear plates 411. The third ear plate 32 is arranged between the two ninth ear plates 411 and then fixed by passing through a pin shaft to realize the hinged connection between the lifting oil cylinder 3 and the transfer case panel 4. It can be understood that when the output end of the lifting oil cylinder 3 contracts or extends, it can drive the transfer case panel 4 to move up and down.

[0031] In this embodiment, as Figure 2 shown, the top of the column 112 is fixedly connected to the bottom end of one end of a small cross beam 114. Two fourth ear plates 115 are fixedly connected to the top of this end of the small cross beam 114, and through holes are also opened on the fourth ear plates 115. As Figure 1 shown, a fifth ear plate 21 is provided at the bottom end of the tipping oil cylinder 2, and a sixth ear plate 22 is provided at the output end. Through holes are opened on both the fifth ear plate 21 and the sixth ear plate 22. The sixth ear plate 22 is arranged between the two fourth ear plates 115 and then fixed by passing through a pin shaft to realize the hinged connection between the tipping oil cylinder 2 and the tipping bracket 1. It can be understood that the output end of the tipping oil cylinder 2 can drive the tipping bracket 1 to move.

[0032] In this embodiment, as Figure 2As shown, the tipping bracket 1 further includes a large crossbeam 117, which is fixedly connected to the middle and lower positions between the two columns 112; two pin shafts brackets 118 are fixedly connected to the large crossbeam 117; as Figure 1 shown, the upper part of the pin shafts bracket 118 is also fixedly connected to the top of the column 112 and the small crossbeam 114 through a connecting crossbeam, and a vehicle frame pin shaft 119 is arranged on the pin shafts bracket 118.

[0033] In this embodiment, the rear end of the vehicle frame is a gantry structure. As Figure 3 shown, two seventh ear plates 71 are arranged on each side of the top end of the gantry 7, and one eighth ear plate 72 is arranged on each side of the bottom end. The eighth ear plate 72 is arranged inside the pin shafts bracket 118, and the vehicle frame pin shaft 119 passes through the eighth ear plate 72 and the pin shafts bracket 118 for fixation, realizing the hinge connection between the bottom of the tipping bracket 1 and the gantry 7. The fifth ear plate 21 at the bottom end of the tipping oil cylinder 2 is arranged between the two seventh ear plates 71, and then fixed through a pin shaft to realize the hinge connection between the tipping oil cylinder 2 and the gantry 7.

[0034] It can be understood that the position where the eighth ear plate 72 is arranged exactly faces the middle part of the pin shafts bracket 118, and the eighth ear plate can be accommodated by the pin shafts bracket; the distance between the seventh ear plates on both sides of the top end of the gantry is equal to the distance between the fourth ear plates on both sides of the tipping bracket 1.

[0035] In this embodiment, since the two ends of the tipping oil cylinder 2 are respectively fixedly connected to the tipping bracket 1 and the gantry 7, and the tipping bracket 1 is hinged to the gantry 7, when the output end of the tipping oil cylinder 2 extends or contracts, the tipping bracket 1 can rotate relative to the gantry 7. In this embodiment, when the output end of the tipping oil cylinder 2 extends, the tipping bracket 1 can rotate downward relative to the gantry 7.

[0036] In this embodiment, as Figure 2 shown, a guide post 5 is fixedly connected between the small crossbeam 114 and the gantry beam 111, and the guide post 5 is perpendicular to the small crossbeam 114 and the gantry beam 111; as Figure 1 shown, the transfer case box plate 4 further includes four longitudinal plates 42, and every two longitudinal plates 42 are arranged in parallel on both sides of the guide post 5 and fixedly connected to the transfer case box plate 4; a guide sleeve 44 is fixedly connected between every two longitudinal plates 42, and the guide sleeve 44 is sleeved outside the guide post 5 and slidably connected to the guide post 5. Two transverse plates 43 are fixedly connected to the side of each longitudinal plate 42 away from the guide post 5, and the transverse plates 43 are also fixedly connected to the transfer case box plate 4 for strengthening the longitudinal plates 42.

[0037] It can be understood that since one end of the lifting oil cylinder 3 is hinged to the tipping bracket 1 and the other end is hinged to the transfer case box plate 4, there is a phenomenon of instability when lifting the transfer case box plate 4, and the sliding connection between the guide sleeve 44 and the guide post 5 can play a role in guiding and supporting the lifting movement of the transfer case box plate 4.

[0038] In this embodiment, as Figure 1 shown, the locking device 6 includes two tenth ear plates 61 with through holes formed therein; the tenth ear plates 61 are fixedly connected to the outermost longitudinal plate 42 and are also fixedly connected to the transverse plate 43 at the top of this side; the locking device 6 further includes a locking flat plate 62, one end of the locking flat plate 62 is open and hinged to the tenth ear plate 61, and a pair of locking protrusions 63 are fixedly arranged in the middle of the locking flat plate 62. As Figure 2 shown, two locking plates 116 are fixedly arranged at one end of the small cross beam 114 far from the column 112, and the locking plates 116 are provided with hook openings. The thickness of the locking flat plate 62 is less than the space between the two locking plates 116, and the locking protrusions 63 can be engaged in the hook openings of the locking plates 116.

[0039] It can be understood that when the lifting oil cylinder 3 lifts the transfer case plate 4 upward to the maximum displacement, an operator can rotate the locking flat plate 62 between the locking plates 116 and engage the locking protrusions 63 in the hook openings of the locking plates 116 to prevent the transfer case plate 4 from suddenly falling.

[0040] Working principle:

[0041] During transportation and transfer, the transfer case plate is in an inclined state. When working, the locking protrusions are removed from the hook openings of the locking plates; at this time, the turning oil cylinder extends to make the turning bracket rotate relative to the vehicle frame, driving the transfer case plate to change from the inclined state to the vertical state;

[0042] The lifting oil cylinder works to drive the transfer case plate to move downward under the action of the guide posts, adjust the depth of plowing according to the operation requirements, and adjust the lifting displacement of the transfer case plate in the vertical direction;

[0043] After the work is completed and the subsoiler needs to be transported and transferred, the lifting oil cylinder works to drive the transfer case plate to move upward to the maximum displacement, then the turning oil cylinder works to drive the turning bracket to return to the inclined state, and finally the locking protrusions are buckled in the hook openings of the locking plates to ensure that the transfer case plate does not fall during transportation and transfer.

[0044] The utility model has reliable and stable actions, which are crucial for realizing deep plowing and subsoiling operations. On the one hand, it realizes the turning of the transfer case, and on the other hand, it realizes the adjustable deep plowing depth. The lifting range can be set within 0 - 150 mm, so as to meet the requirements of customers for different deep plowing depths, and it can ensure the stability of the vertical movement of the transfer case body through the guiding device and ensure the stability of the transfer case body during transfer through the locking device.

[0045] Although the specific implementation manners of the present utility model have been described in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present utility model. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solutions of the present utility model are still within the protection scope of the present utility model.
