Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, specifically relating to a rotary plow-rotor integrated machine. Background Technology

[0002] Among agricultural machinery and equipment, reversible plows and rotary tillers are relatively common agricultural tools. Reversible plows are mainly composed of plowshares, plowshares, plow blades, plow teeth and hydraulic systems, and are mainly used for deep loosening, plowing and tilling of farmland. Rotary tillers are mainly composed of transmission systems, rotating cutter heads, bucket frames and adjustment mechanisms, and are used for tilling soil.

[0003] The reversible plow and rotary tiller mentioned above are conventional structures, and both are used independently as a method of operation in the farming process. Different agricultural machinery is selected based on different agricultural products. Rotary tillers have a fast working speed, but their disadvantage is insufficient depth, mostly within 15 cm. Reversible plows can easily reach a working depth of more than 20 cm. Their disadvantages are that plowing consumes a lot of fuel, the working speed is relatively slow, and after plowing, the soil is in clumps, requiring further rotary tillage to break up the soil. Summary of the Invention

[0004] Based on the problems existing in the background technology of reversible plows, the purpose of this invention is to design a reversible plow-rotary integrated machine, which adds a rotary tillage mechanism to the reversible plow, and has both plowing and rotary tillage effects. The tilled soil is loose and soft, and a separation box is designed to reasonably distribute power.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A rotary plow and rotary tiller is provided, comprising a rotary frame and a suspension frame movably connected. An input shaft is installed inside the suspension frame. An automatic separation box is installed at the front end of the rotary frame. A rotary plow assembly and a vertical rotary tiller assembly are evenly and alternately installed on the plow frame of the rotary frame. The vertical rotary tiller assembly includes an intermediate auger box, an upper cutter shaft, and a lower cutter shaft. The two output shafts of the automatic separation box drive two transmission shafts through a corner box. The two transmission shafts drive the upper cutter shaft and the lower cutter shaft respectively.

[0007] Furthermore, the automatic separation box includes a box body, an input shaft connected to the drive wheel of the box body, and input power transmitted to two output shafts through a gear assembly. Each output shaft is fitted with a slotted connector, and a friction plate is installed inside the slotted connector. The friction plate is held in place by a pressure bearing seat. One end of a spring is connected to the pressure bearing seat, and the other end of the spring is connected to a sliding bearing seat. The lower lever is connected to the first sliding bearing seat, and the upper lever is connected to the second sliding bearing seat.

[0008] Furthermore, the paddle shaft of the lower paddle is connected to the lower clutch linkage outside the housing via a lower connecting rod, and the paddle shaft of the upper paddle is connected to the upper clutch linkage outside the housing via an upper connecting rod. The lower clutch linkage and the upper clutch linkage are respectively connected to the first and second ends of the clutch connecting plate, and the third end of the clutch connecting plate is connected to the hydraulic cylinder.

[0009] Furthermore, the gear assembly includes two transition shafts, with a transition wheel installed at one end of each transition shaft and a transition conical wheel installed at the other end. The driving gear meshes with the transition wheels of the two transition shafts respectively, and the transition conical wheel meshes with the transition wheel on the output shaft. A positioning sleeve is installed at the transition wheel.

[0010] Furthermore, an output shaft sealing seat is installed on the housing of the automatic separation box.

[0011] Furthermore, the reversible plow assembly includes a fixing plate mounted on the plow frame, the fixing plate being connected to the upper plow body and the lower plow body respectively via two plow columns.

[0012] Furthermore, the upper output end of the auger box is connected to the upper cutter shaft, and the lower output end of the auger box is connected to the lower cutter shaft, on which rotary tillage blades are mounted.

[0013] The above technical solution can achieve the following beneficial effects:

[0014] This invention integrates deep plowing and rotary tillage, solving the problem of rotary tillage of large clumps of soil after deep plowing with a reversible plow, making the soil soft. The rotary tillage mechanism also adopts an up-and-down flipping structure to coordinate with the reversible plow.

[0015] This invention also includes an automatic separation box. On one hand, the separation box provides power to the rotary tillage mechanism that is flipping up and down. On the other hand, it distributes power to the rotary tillage mechanism that is flipping up and down, providing power output to the rotary tillage mechanism that is performing rotary tillage work downwards, while stopping the power supply to the rotary tillage mechanism that is not performing work upwards, preventing it from running idle. This is beneficial for power distribution, ensuring that the rotary tillage mechanism has sufficient power during operation, reducing unnecessary power loss, and saving fuel consumption.

[0029] The invention will be further described below with reference to the accompanying drawings:

[0030] Example: Figure 1-6As shown, a rotary tiller integrated machine includes a rotary frame 1 movably connected to a suspension frame 11. An input shaft 3 is installed inside the suspension frame, which is connected to a large tractor. The tractor's power output is connected to the input shaft 3. The rotary frame 1 includes a frame composed of an inclined plow frame. An automatic separation box 2 is installed on the frame. A rotary plow assembly 4 and a vertical rotary tiller assembly 5 are installed on the plow frame in a uniformly alternating manner. The rotary plow assembly 4 includes a fixing plate 12 connected to the plow frame. The upper part of the fixing plate 12 is equipped with an upper plow body via an upper plow column, and the lower part of the fixing plate 12 is equipped with a lower plow column. The lower plow body is installed. The vertical rotary tiller assembly 5 includes an intermediate auger box 6, which is fixed to the plow frame by a connector. The upper output end of the auger box is connected to the upper cutter shaft 43, and the lower output end of the auger box is connected to the lower cutter shaft 44. Rotary tillers 42 are installed on the cutter shaft. The automatic separation box 2 has two output shafts. The two output shafts drive two transmission shafts through a corner box. The two transmission shafts drive the upper cutter shaft and the lower cutter shaft respectively through the auger box. That is, the first transmission shaft 7 drives the lower cutter shaft to rotate through several auger boxes, and the second transmission shaft 8 drives the upper cutter shaft to rotate through several auger boxes.

[0031] in Figure 7 , 8 Figure 9 shows the structure of the cutter box. The cutter box includes an outer box and two drive shafts running through the box. Each drive shaft is equipped with a first conical wheel. The upper first conical wheel meshes with the conical wheel of the upper cutter shaft, and the lower first conical wheel meshes with the conical wheel of the lower cutter shaft.

[0032] Figure 10 Figure 11 shows the corner box structure. The output shaft extending from the automatic separation box 2 is located inside the corner box, and a conical wheel is installed on the output shaft. The conical wheel meshes with a conical wheel installed at the end of the drive shaft. The entire corner box is at a certain angle, so that the drive shaft and the output shaft are at a reasonable angle, which also facilitates the manufacturing requirements of the conical wheel meshing and the relationship between machine parts.

[0033] Figure 4 As shown, the automatic separation box 2 includes a box body 20. An upper cover plate 16 and a lower cover plate 19 are installed on the top and bottom of the box body, respectively. An observation port cover plate is also installed on the side of the box body. An upper paddle shaft 22 and a lower paddle shaft 23 extend from the inside to the outside of the box body. One end of the upper connecting rod 15 is hinged to the upper paddle shaft 22, and the other end is connected to the upper clutch connecting rod 17. One end of the lower connecting rod 14 is hinged to the lower paddle shaft 23, and the other end is connected to the lower clutch connecting rod 13. The upper clutch connecting rod 17 and the lower clutch connecting rod 13 are respectively connected to two ends of the clutch connecting plate 18. The third end of the clutch connecting plate 18 is hinged to the hydraulic cylinder 21. The middle rotating part of the clutch connecting plate 18 is installed on the side of the box body. The clutch connecting plate 18 is rotated by the extension and retraction of the hydraulic cylinder, thereby pulling the clutch connecting rod.

[0034] Figure 6As shown, a drive wheel 24 is installed in the middle part of the automatic separation box 2. The left and right sides of the drive wheel 24 mesh with transition wheels 25 respectively. One end of the transition shaft 26 is equipped with the transition wheel 25, and the other end is equipped with a transition cone wheel 27. Figure 5 As shown, the automatic separation box 2 houses a first output shaft 28 and a second output shaft 29. The first output shaft is sequentially fitted with a transition conical wheel 30, a slotted connector 31, a friction plate 37, a pressure bearing plate 36, a spring sleeve 32, a spring 33, a sliding bearing seat 34, and a rotating shaft collar 35. The sliding bearing seat 34 and the rotating shaft collar 35 are connected to the lower lever 38. The transition conical wheel 30 of the first output shaft meshes with one of the transition conical wheels 27. The slotted connector 31 of the first output shaft has an annular groove, within which friction plates are arranged. The friction plate 37 is held in place by the pressure bearing plate 36. A spring sleeve 32 is installed on the right side of the pressure bearing plate 36, and a spring 33 is installed on the spring sleeve 32. The right end of the spring 33 is connected to the sliding bearing seat 34 and the rotating shaft collar 35. Similarly, the structure of the second output shaft 29 is the same as that of the first output shaft. The difference is that the sliding bearing seat 34 and the rotating shaft collar 35 at the right end of the second output shaft 29 are connected to the upper paddle 39. Finally, the lower paddle 38 is hinged to the lower paddle shaft 23, and the upper paddle shaft 22 is hinged to the upper paddle 39.

[0035] In the above embodiment, a positioning sleeve 40 is installed at the transition wheel 30, and an oil seal seat 41 is installed on the housing.

[0036] In the above embodiments, the number of friction pads 37 is several layers, which can be selected and set according to the actual situation.

[0037] In the above embodiments, the right ends (ends) of the first output shaft 28 and the second output shaft 29 are both located on the large bearing seat on the side of the housing.

[0038] In the above embodiment, a depth-limiting wheel 10 is also installed on the plow frame.

[0039] Specific operating principle:

[0040] The suspension frame of the present invention is connected to a large tractor. The output part of the tractor is connected to the input shaft 3 of the present invention. The input shaft drives the drive wheel 24 in the automatic separation box 2 to rotate. The drive wheel 24 transmits power sequentially along the transition wheel 25, the transition shaft 26, the transition wheel 25 and the transition wheel 30, and finally drives the first output shaft 28 and the second output shaft 29 to rotate respectively. The first output shaft 28 and the second output shaft 29 drive two transmission shafts respectively after passing through the corner box 9. The two transmission shafts drive the upper cutter shaft and the lower cutter shaft respectively through the cutter box.

[0041] Figure 3As shown, when a large tractor drives a rotary tiller to operate, the rotary tiller assembly 4 and the vertical rotary tiller assembly 5 are divided into upper and lower parts. Regardless of how the rotary tiller rotates, the lower rotary body and tiller blades contact the ground for tilling, while the upper rotary tiller blades idle during operation. This not only consumes power but also increases wear and tear. Therefore, the automatic separation box 2 can also distribute power. For example, if the first output shaft 28 drives the first transmission shaft 7 through several cutter boxes to rotate the lower cutter shaft, and the second output shaft drives the second transmission shaft through several cutter boxes to rotate the upper cutter shaft... When the cutter shaft rotates, and the lower cutter shaft is working from below, the upper cutter shaft is in an idle state from above. At this time, the hydraulic cylinder 21 can be controlled to retract, pulling the clutch connecting plate 18 to rotate, which in turn pulls the upper clutch connecting rod 17. This causes the upper connecting rod 15 to drive the upper paddle shaft 22 to rotate, causing the upper paddle 39 to drive the sliding bearing seat 34 and the rotating shaft collar 35 to move to the left, compressing the spring. This, in turn, causes the pressure bearing plate 36 to compress the friction plate 37. The friction plate 37 abuts against the slotted connector 31, stopping the second output shaft from rotating. This brakes the second output shaft, stopping its rotation, and consequently, the second transmission shaft cannot drive the upper cutter shaft to rotate. In the above actions, the lower clutch connecting rod 13 does not affect the rotation of the first output shaft, and the power is normally transmitted to the lower cutter shaft through the first transmission shaft. Similarly, when the machine is flipped, and the upper cutter shaft is working from below, the lower cutter shaft is in an idle state from above. That is, after the hydraulic cylinder extends, it drives the clutch connecting plate 18 to rotate. Then, according to the above operating principle, the first output shaft is braked, while the second output shaft outputs power to drive the upper cutter shaft to rotate and work. The automatic separation box structure and principle described above enable the first output shaft and the second output shaft to separate and connect. When the first output shaft separates, the second output shaft automatically connects, and vice versa.

[0042] The above descriptions are all preferred embodiments of the present invention. For those skilled in the art, any modifications to the present invention in various equivalent forms without departing from the principle of the present invention shall fall within the protection scope of the appended claims.
