When advancing under the pressure of the soil by relying on gravity or the gravity of the frame indirectly, the soil is compacted and secondarily pulverized, and the operation is simple. However, the above three-point suspension device is rigidly connected to the tractor. When the tractor travels straight, it is okay. When the tractor needs to turn, under the action of the lateral shear force, the rigid connection part will probably be deformed or even damaged with a certain probability. Summary of the Invention

The C-shaped mounting frame one and the C-shaped mounting frame two are distributed in a scissor shape with the limiting block as the center. An installation vertical rod passes through the C-shaped mounting frame one and the C-shaped mounting frame two. The limiting block abuts against the installation vertical rod, and the installation vertical rod squeezes the same-side arms of the C-shaped mounting frame one and the C-shaped mounting frame two left and right. When the C-shaped mounting frame one and the C-shaped mounting frame two rotate to a state close to horizontal, the limiting block slides in a direction away from the installation vertical rod. The top and bottom ends of the installation vertical rod are connected to a fixing frame, and the fixing frame is connected to the tractor.

[0004] Preferably, the fixing frame is configured as a C-shaped structure for connection to the tractor.

[0005] Preferably, the flexible fixing component further includes:

[0006] An outer rotating ring seat, the two side arms of the C-shaped mounting frame one are fixedly connected to the outer rotating ring seat, and the distance between the two side arms of the C-shaped mounting frame two is smaller than the distance between the two side arms of the C-shaped mounting frame one;

[0007] An outer rotating sleeve, the outer rotating sleeve is connected to the outer rotating ring seat, and four driving inclined grooves one are circumferentially arranged on the outer rotating sleeve. A driving slider one is slidably connected in the driving inclined groove one;

[0008] Inner rotating sleeve, the inner rotating sleeve is rotatably installed inside the outer rotating sleeve. Four driving inclined grooves II are circumferentially formed on the inner rotating sleeve. The driving slider II is slidably connected to the driving inclined groove II, and the inclination direction of the driving inclined groove II is opposite to that of the driving inclined groove I.

[0009] Central mounting seat, the inner rotating sleeve is sleeved on the central mounting seat. The limiting block is connected to the central mounting seat. The two side arms of the C-shaped mounting frame II penetrate through the outer rotating ring seat and are connected to the inner rotating sleeve. The driving slider I and the driving slider II are installed on the central mounting seat.

[0010] Preferably, a first stepped surface for clamping the inner rotating sleeve is provided outside the central mounting seat.

[0011] Preferably, mounting holes are formed on the fixed cross beam. The end of the outer rotating sleeve away from the outer rotating ring seat penetrates through the mounting holes and is connected to the fixed mounting seat. The fixed mounting seat is fixedly connected to the fixed cross beam through the side mounting plate. The connecting spring is connected between the central mounting seat and the fixed mounting seat.

[0012] Preferably, a second stepped surface is provided outside the fixed mounting seat. The inner wall of the outer rotating sleeve at the end away from the outer rotating ring seat is installed on the second stepped surface through a bearing I.

[0013] Preferably, the inner wall of the outer rotating sleeve near the outer rotating ring seat is connected to the inner rotating sleeve through a bearing II.

[0014] Preferably, an arc-shaped groove for limiting the middle section of the mounting vertical rod is provided on the limiting block.

[0015] Preferably, a limiting clamping rod is screwed on the fixing frame. The limiting clamping rod is clamped between the C-shaped mounting frame I and the C-shaped mounting frame II to limit the falling of the mounting vertical rod.

[0016] Compared with the prior art, the advantages of the present invention are as follows:

[0017] (1) A hydraulic turning plow suspension device disclosed by the present invention. Two flexible fixing components are installed at the front end in the traveling direction of the hydraulic turning plow through a fixed cross beam, and the flexible fixing components are used to connect with the tractor. When the tractor drives the hydraulic turning plow to turn synchronously, the tractor drives the fixing frame connected thereto and the mounting vertical rod connected to the fixing frame to squeeze the same-side arms of the C-shaped mounting frame I and the C-shaped mounting frame II, thereby driving the C-shaped mounting frame I and the C-shaped mounting frame II to rotate to a state close to horizontal, and the limiting block for limiting the mounting vertical rod releases the limit on the mounting vertical rod. In this way, when the tractor drives the hydraulic turning plow to turn, a certain displacement amount is given to the mounting vertical rod between the C-shaped mounting frame I and the C-shaped mounting frame II. Compared with the rigid connection, the lateral shear force is converted into the rotational force of the C-shaped mounting frame I and the C-shaped mounting frame II, so as to realize the flexible connection of the suspension device and improve the service life of the suspension device.

[0018] (2)A hydraulic tipping plow suspension device disclosed by the present invention. When the tractor drives the hydraulic tipping plow to turn synchronously, the tractor drives the fixed frame connected thereto and the installation vertical rod connected to the fixed frame to squeeze the same-side arms of the first C-shaped mounting frame and the second C-shaped mounting frame. The lateral shear force is converted into the rotational force of the first C-shaped mounting frame and the second C-shaped mounting frame, the outer rotating sleeve and the inner rotating sleeve respectively connected to the first C-shaped mounting frame and the second C-shaped mounting frame, thereby driving the first C-shaped mounting frame and the second C-shaped mounting frame to rotate to a state close to horizontal. At this time, while the outer rotating ring seat connected to the first C-shaped mounting frame and the outer rotating sleeve connected to the outer rotating ring seat rotate, the inner rotating sleeve connected to the second C-shaped mounting frame rotates. The first C-shaped mounting frame and the second C-shaped mounting frame drive the rotation of the outer rotating sleeve and the inner rotating sleeve respectively. In this way, under the cooperation of the driving slider two and the driving slider one, the central mounting seat and the limiting block mounted on the central mounting seat move away from the installation vertical rod to release the limit on the installation vertical rod, and the connecting spring contracts. In this way, the lateral shear force can be converted into the contraction force of the connecting spring, and after the tractor drives the hydraulic tipping plow to complete the turn, the connecting spring extends and resets to release the lateral shear force to drive the first C-shaped mounting frame, the second C-shaped mounting frame and the limiting block to reset, thereby realizing the reset of the installation vertical rod. In this way, after the lateral shear force generated by the tractor driving the hydraulic tipping plow to turn is applied to the same-side arms of the first C-shaped mounting frame and the second C-shaped mounting frame, it is converted into the rotational force of the first C-shaped mounting frame and the second C-shaped mounting frame, the outer rotating sleeve and the inner rotating sleeve respectively connected to the first C-shaped mounting frame and the second C-shaped mounting frame, thus realizing the flexible connection of the suspension device.

[0028] Embodiment

[0029] Next, the present invention will be further described in conjunction with the accompanying drawings.

[0030] As Figures 1 to 6 shown, a hydraulic reversible plow suspension device provided in this embodiment includes: a fixed cross - beam 2 located at the front end in the traveling direction of the hydraulic reversible plow 1. Two flexible fixing components 3 are symmetrically installed on the fixed cross - beam 2. The flexible fixing component 3 includes: a C - shaped mounting frame one 4, a C - shaped mounting frame two 5, and a limit block 6. The C - shaped mounting frame one 4 and the C - shaped mounting frame two 5 are distributed in a scissor - type around the limit block 6. The installation vertical rod 7 passes through the C - shaped mounting frame one 4 and the C - shaped mounting frame two 5. The limit block 6 abuts against the installation vertical rod 7. The installation vertical rod 7 squeezes the same - side arms of the C - shaped mounting frame one 4 and the C - shaped mounting frame two 5 left and right, and the C - shaped mounting frame one 4 and the C - shaped mounting frame two 5 rotate to a state close to horizontal. The limit block 6 slides in a direction away from the installation vertical rod 7. The top and bottom ends of the installation vertical rod 7 are connected to the fixed frame 8, and the fixed frame 8 is connected to the tractor.

[0031] The working principle and beneficial effects of the above - mentioned technical solution are as follows:

[0032] A hydraulic tilting plow suspension device provided by the present invention. Two flexible fixing components 3 are installed at the front end in the traveling direction of the hydraulic tilting plow 1 through a fixing cross beam 2, and the flexible fixing components 3 are used to connect with a tractor. When the tractor drives the hydraulic tilting plow 1 to turn synchronously, the tractor drives the fixing frame 8 connected thereto and the mounting vertical rod 7 connected to the fixing frame 8 to squeeze the same-side arms of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, thereby driving the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5 to rotate to a state close to horizontal, and the limiting block 6 for limiting the mounting vertical rod 7 releases the limit on the mounting vertical rod 7. A hydraulic tilting plow suspension device disclosed by the present invention gives a certain displacement amount to the mounting vertical rod 7 between the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5 when the tractor drives the hydraulic tilting plow 1 to turn. Compared with a rigid connection, the lateral shear force is converted into the rotational force of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, so as to realize the flexible connection of the suspension device and improve the service life of the suspension device.

[0033] In one embodiment, the fixing frame 8 is provided with a C-shaped structure for connection with the tractor.

[0034] The working principle and beneficial effects of the above technical solution are as follows:

[0035] The fixing frame 8 is provided with a C-shaped structure to facilitate the connection of the tractor thereto through a hook with a chain.

[0036] In one embodiment, the flexible fixing component 3 further includes:

[0037] An outer rotating ring seat 9. The two side arms of the C-shaped mounting frame one 4 are fixedly connected to the outer rotating ring seat 9, and the distance between the two side arms of the C-shaped mounting frame two 5 is smaller than the distance between the two side arms of the C-shaped mounting frame one 4;

[0038] An outer rotating sleeve 10. The outer rotating sleeve 10 is connected to the outer rotating ring seat 9. Four driving inclined grooves one 13 are circumferentially formed on the outer rotating sleeve 10, and a driving slider one 14 is slidably connected in the driving inclined groove one 13;

[0039] An inner rotating sleeve 11. The inner rotating sleeve 11 is rotatably installed in the outer rotating sleeve 10. Four driving inclined grooves two 15 are circumferentially formed on the inner rotating sleeve 11, and a driving slider two 16 is slidably connected in the driving inclined groove two 15. The inclination direction of the driving inclined groove two 15 is opposite to that of the driving inclined groove one 13;

[0040] A central mounting seat 12. The inner rotating sleeve 11 is sleeved on the central mounting seat 12. The limiting block 6 is connected to the central mounting seat 12. The two side arms of the C-shaped mounting frame two 5 pass through the outer rotating ring seat 9 and are connected to the inner rotating sleeve 11. The driving slider one 14 and the driving slider two 16 are installed on the central mounting seat 12.

[0041] The working principle and beneficial effects of the above technical solution are as follows:

[0042] When the tractor drives the hydraulic reversible plow 1 to turn synchronously, the tractor drives the fixed frame 8 connected thereto and the installation vertical rod 7 connected to the fixed frame 8 to squeeze the same-side arms of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, thereby driving the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5 to rotate to a state close to horizontal. At this time, while the outer rotating ring seat 9 connected to the C-shaped mounting frame one 4 and the outer rotating sleeve 10 connected to the outer rotating ring seat 9 rotate, the inner rotating sleeve 11 connected to the C-shaped mounting frame two 5 rotates. Since the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5 are arranged in a scissor-like manner, when the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5 rotate to a state close to horizontal, the rotation directions of the outer rotating sleeve 10 and the inner rotating sleeve 11 driven by them are opposite, and both the outer rotating sleeve 10 and the inner rotating sleeve 11 are sleeved on the central mounting seat 12. The driving inclined groove one 13 opened on the outer rotating sleeve 10 and the driving inclined groove two 15 opened on the inner rotating sleeve 11 have opposite inclination directions. In this way, under the cooperation of the driving slider two 16 and the driving slider one 14, the central mounting seat 12 and the limiting block 6 mounted on the central mounting seat 12 are driven to move away from the installation vertical rod 7 to release the limitation on the installation vertical rod 7. In this way, after the lateral shear force generated by the tractor driving the hydraulic reversible plow 1 to turn is applied to the same-side arms of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, it is converted into the rotational force of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, and the outer rotating sleeve 10 and the inner rotating sleeve 11 respectively connected to the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, thus realizing the flexible connection of the suspension device.

[0043] In one embodiment, a first stepped surface 22 for clamping the inner rotating sleeve 11 is provided outside the central mounting seat 12.

[0044] The beneficial effects of the above technical solution are as follows:

[0045] The setting of the first stepped surface 22 is for the convenient rotational installation of the inner rotating sleeve 11 on the central mounting seat 12.

[0046] In one embodiment, an installation hole 17 is opened on the fixed cross beam 2. The end of the outer rotating sleeve 10 far from the outer rotating ring seat 9 passes through the installation hole 17 and is connected to the fixed mounting seat 18. The fixed mounting seat 18 is fixedly connected to the fixed cross beam 2 through the side mounting plate 19. The connecting spring 25 is connected between the central mounting seat 12 and the fixed mounting seat 18.

[0047] The working principle and beneficial effects of the above technical solution are as follows:

[0048] When the lateral shear force generated by the tractor driving the hydraulic reversible plow 1 to turn squeezes the same-side arms of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, it is converted into the rotational force of the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, and the outer rotating sleeve 10 and the inner rotating sleeve 11 respectively connected to the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5. Then, the limiting block 6 driven by the central mounting seat 12 moves away from the mounting vertical rod 7 to release the limit on the mounting vertical rod 7, and the connecting spring 25 contracts. In this way, the lateral shear force can be converted into the contraction force of the connecting spring 25. After the tractor drives the hydraulic reversible plow 1 to complete the turn, the connecting spring 25 extends and resets to release the lateral shear force, so as to drive the C-shaped mounting frame one 4, the C-shaped mounting frame two 5 and the limiting block 6 to reset, thereby realizing the reset of the mounting vertical rod 7.

[0049] In one embodiment, a second stepped surface is provided outside the fixed mounting seat 18, and the inner wall of the outer rotating sleeve 10 away from the outer rotating ring seat 9 is mounted on the second stepped surface through a first bearing 20.

[0050] The beneficial effects of the above technical solution are:

[0051] The setting of the second stepped surface facilitates the installation of the first bearing 20, so as to realize the rotatable installation of the outer rotating sleeve 10 on the fixed mounting seat 18.

[0052] In one embodiment, the inner wall of the outer rotating sleeve 10 near the outer rotating ring seat 9 is connected to the inner rotating sleeve 11 through a second bearing 21.

[0053] The beneficial effects of the above technical solution are:

[0054] The setting of the second bearing 21 facilitates the reverse rotation of the outer rotating sleeve 10 and the inner rotating sleeve 11.

[0055] In one embodiment, an arc-shaped groove 23 for limiting the middle section of the mounting vertical rod 7 is provided on the limiting block 6.

[0056] The beneficial effects of the above technical solution are:

[0057] The setting of the arc-shaped groove 23 facilitates the limitation of the mounting vertical rod 7.

[0058] In one embodiment, a limiting clamping rod 26 is screwed on the fixed frame 8, and the limiting clamping rod 26 is clamped between the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5 to limit the downward movement of the mounting vertical rod 7.

[0059] The working principle and beneficial effects of the above technical solution are:

[0060] After the mounting vertical rod 7 is inserted into the C-shaped mounting frame one 4 and the C-shaped mounting frame two 5, the top and bottom ends of the mounting vertical rod 7 are connected to the fixed frame 8, and then the limiting clamping rod 26 is inserted into the fixed frame 8.Figure 2 As shown, the limiting clamping rod 26 is clamped in the V-shaped groove formed by the first C-shaped mounting bracket 4 and the second C-shaped mounting bracket 5, thereby preventing the installation vertical rod 7 from falling, so as to achieve the maximum degree of release of the top and bottom ends of the installation vertical rod 7 from the two side arms of the first C-shaped mounting bracket 4, thereby completing the extrusion thereof.

[0061] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
