Description

Technical Field

[0001] The invention relates to an agricultural implement for managing sugarcane ratoons, in particular to a sugarcane ridge breaking and stubble leveling machine with a stubble leveling cutter disc capable of floating in imitation of terrain, belonging to the technical field of agricultural machinery and equipment. Background Art

[0002] Sugarcane perennial roots refer to the sugarcane stumps left in the sugarcane field after the sugarcane harvest in the previous year. After proper agricultural management, the sugarcane perennial roots can sprout out of the ground again and grow into sugarcane plants next year. Sugarcane perennial roots are generally useful for 2-3 years, and can be as long as 4-5 years. Therefore, sugarcane grown from sugarcane perennial roots accounts for more than 2 / 3 of the sugarcane planting area. However, after the sugarcane is harvested, especially manually harvested, the sugarcane perennial roots left in the sugarcane field are often higher than the ground. If they are not treated by leveling, breaking ridges and loosening stumps, applying base fertilizer, covering soil and film, the sugarcane stubble emerging from the ground will quickly germinate and grow at a high position, and the roots do not have good soil coverage and fertilizer nourishment. The sugarcane seedlings will not get enough nutrients during the growth process, which will cause the sugarcane plants to die or fail to thrive in the later stage, seriously affecting the sugarcane yield. Therefore, after the sugarcane is harvested, agricultural management of the sugarcane perennial roots is required in a timely manner.

[0003] Most of my country's sugarcane is planted in the hilly and mountainous areas in the south, and most of the sugarcane fields are hilly slopes. The existing sugarcane perennial root stubble equipment on the market is generally suspended and driven by a tractor. The cutting depth control of the stubble device equipped with it generally adopts hydraulic lifting adjustment and depth limiting wheel depth. The specific control principle is to first raise the depth limiting wheel to a sufficiently high position, and then use the tractor's hydraulic lifting device to adjust the stubble disc to a predetermined cutting depth as needed under the working state. At this time, stop the operation and keep the cutting tip at the predetermined depth position in the soil. After the depth limiting wheel is lowered to contact with the ground, the depth limiting wheel is fixed, thereby realizing the stubble operation of the set depth. This stubble cutting depth control method cannot make adaptive adjustments according to the undulations of the terrain, and can only be adjusted manually. When working on uphill terrain, the disc will be too deep in the soil, resulting in damage to the perennial roots of the sugarcane. When working on downhill terrain, the cutting depth will not be enough, resulting in the phenomenon of too long stubble of the sugarcane. Once the depth limiting wheel is adjusted and fixed, it can only limit the cutting disc to a certain cutting depth. It has a good depth limiting effect on leveling sugarcane fields, but it cannot play a role in maintaining a constant cutting depth in the soil for undulating sugarcane fields. It can be seen that the stubble disc equipped with the existing sugarcane perennial root stubble equipment cannot well adapt to the stubble operation needs of sugarcane in undulating sugarcane fields in terms of cutting depth control. In addition, the existing stubble discs are mostly driven by hydraulic motors to rotate, and need to be equipped with corresponding hydraulic control systems, which have a relatively complex structure and are not convenient for maintenance. Summary of the invention

[0004] The purpose of the present invention is to provide a sugarcane ridge breaking and stubble leveling machine with a stubble leveling disc that can float in imitation of the terrain. The stubble leveling disc equipped with the machine can make adaptive floating adjustments according to the undulating changes in the terrain of the sugarcane field, thereby achieving a better stubble leveling effect. Moreover, the stubble leveling disc is driven by a purely mechanical chain transmission, with high transmission efficiency, simple structure and easy maintenance.

The auxiliary frame is provided with left and right profiling wheels on the outer sides of the two stubble cutter discs respectively through front wheel frames extending obliquely forward and downward at the left and right ends of the auxiliary frame, and elastic pushing mechanisms for swinging the front wheel frames downward are respectively provided on the front ends of the left and right front wheel frames of the auxiliary frame, and the front wheel frames are elastically pushed by the elastic pushing mechanisms to make the profiling wheels keep elastically pressing on the bottom surface of the ridge furrow of the sugarcane field, thereby driving the stubble cutter disc to realize profiling cutting and stubble cutting of the sugarcane field.

[0007] The stubble-leveling device of the sugarcane ridge-breaking and stubble-leveling machine is provided with a stubble-leveling disc that can float up and down with the auxiliary frame, and the profiling wheel drives the auxiliary frame and the stubble-leveling disc to float up and down accordingly according to the ups and downs of the ridge bottom. Whether working on flat ground, uphill or downhill terrain, the stubble-leveling disc can be well maintained at a certain cutting depth position, and there will be no phenomenon that the cutting blade is too deep into the soil due to uphill, thereby damaging the sugarcane perennial roots, or the cutting blade is too high from the ground due to downhill, thereby causing the sugarcane stubble to be too long. In addition, the stubble-leveling disc of the sugarcane ridge-breaking and stubble-leveling machine is driven by a purely mechanical chain transmission, and is provided with an elastic tensioning structure to keep the chain always tensioned, which can well meet the needs of the stubble-leveling disc floating up and down, and has higher transmission efficiency than the conventional hydraulic motor drive, and has the advantages of simple structure, low cost, convenient disassembly and assembly, and easy maintenance.

In the description of the present invention, the directional words "front", "rear", "left" and "right" are defined based on the perspective of the tractor driver facing forward when operating the sugarcane ridging and stubble machine at the front end.

[0017] like Figure 1-Figure 4 As shown, the sugarcane ridging and stubble leveling machine is provided with a frame 1, a stubble leveling device 2 is mounted at the lower front end of the frame 1, a rotary tillage device 3 is mounted behind the stubble leveling device 2, a depth limiting wheel 5 is mounted on the frame 1 at a position centered on the left and right and located between the stubble leveling device 2 and the rotary tillage device 3 through a downwardly extending intermediate wheel frame 4, a main transmission shaft 6 is mounted at the front end of the frame 1 at a position centered on the left and right above the stubble leveling device 2, a universal coupling 7 is connected to the front end of the main transmission shaft 6, and the universal shaft coupling 7 receives the PTO output power of the matching tractor and transmits the power to the stubble leveling device 2 and the rotary tillage device 3 through the main transmission shaft 6.

[0018] The stubble-leveling device 2 is provided with a sub-frame 8 below the front end of the frame 1. The upper end of the sub-frame 8 is slidably connected to the sliding bearing 1.1 installed corresponding to the frame 1 through a sliding guide column 8.1, so that the sub-frame 8 can move up and down relative to the frame 1; the lower end of the middle part of the sub-frame 8 is fixedly connected to two symmetrically arranged transmission gear boxes 9 on the left and right, and the transmission gear box 9 is provided with an input shaft extending backward and an output shaft extending downward. The output ends of the two transmission gear boxes 9 are respectively connected to a stubble-leveling cutter disc 10. The main transmission shaft 6 drives the input shafts of the two transmission gear boxes 9 to rotate at the same time through a set of chain transmission components with an elastic tensioning structure. The output shafts of the two transmission gear boxes 9 drive the two stubble cutter discs 10 to rotate; the left and right ends of the auxiliary frame 8 are respectively provided with left and right profiling wheels 12 on the outer sides of the two stubble cutter discs 10 through the front wheel frames 11 extending obliquely forward and downward, the upper ends of the front wheel frames 11 are hinged on the auxiliary frame 8, and the auxiliary frame 8 is also respectively provided with elastic pushing mechanisms at the front ends of the left and right front wheel frames 11 for pressing the front wheel frames 11 backward, and the elastic pushing mechanisms elastically push the front wheel frames 11 so that the profiling wheels 12 remain elastically pressed against the bottom surface of the ridge furrow of the sugarcane field, thereby driving the stubble cutter discs 10 to achieve profiling cutting and stubble cutting of the sugarcane field.

[0019] Furthermore, the chain transmission assembly is provided with a driving sprocket 13 fixedly connected to the main transmission shaft 6, two driven sprockets 14 fixedly connected to the input shafts of the two transmission gear boxes 9 respectively below the driving sprocket 13, a chain ring 15 surrounding the outer periphery of the driving sprocket 13 and the two driven sprockets 14 and forming an engagement, and a guide sprocket 16 fixedly installed on the auxiliary frame 8 and located at a position slightly above the two driven sprockets 14 and engaging with the chain ring 15 from the outside; the elastic tensioning structure is provided with left and right tensioning sprockets 17 respectively engaging with the chain ring 15 from the outside of the left and right sides and tensioning the chain ring 15, the two tensioning sprockets 17 are respectively installed at the upper ends of two left and right swing arms 18 arranged in an eight-shaped shape, a tension spring 19 is provided between the upper ends of the two swing arms 18 for lateral elastic pulling, and the lower ends of the two swing arms 18 are respectively hinged on the hinge seats 1.2 correspondingly installed on the frame 1.

[0020] Furthermore, the chain drive assembly may be replaced by a belt drive assembly.

[0021] Furthermore, the left and right ends of the sub-frame 8 are provided with mounting seats 27 that can move left and right along the sub-frame 8 and can be locked. The mounting seats 27 are fixed to the sub-frame 8 through U-shaped screws. The upper ends of the left and right front wheel frames 11 are respectively hinged to the mounting seats 27 at the left and right ends of the sub-frame, and the left and right elastic push mechanisms are also correspondingly mounted on the left and right mounting seats 27. By adjusting the positions of the left and right mounting seats 27 on the sub-frame 8, the spacing between the left and right contour wheels 12 can be changed to match the spacing between the furrows on both sides of the sugarcane ridge. Furthermore, the elastic pushing mechanism is provided with a forward-inclined push rod 20, the lower end of which is hinged on the front wheel frame 11, and a mounting seat 27 is fixedly provided with a forward-extending support arm 21 above the front wheel frame 11, a sliding sleeve 22 is hinged at the front end of the support arm 21, and an upper nut is provided for locking after the upper end of the push rod 10 slides through the sliding sleeve 22, and an adjusting spring 23 is sleeved on the rod body of the push rod 20 below the sliding sleeve 22 and a lower nut is provided to press the adjusting spring 23, thereby realizing the elastic pushing of the front wheel frame 11 to swing backward.

[0022] Furthermore, the stubble cutter disc 10 is provided with a flat disc cutter holder, on which a group of cutting blades extending radially and having adjustable extension lengths are fixedly mounted.

[0023] Furthermore, the frame 1 is provided with a fertilizing device 24 above the rotary tillage device 3, and the rear end of the frame 1 is provided with a soil covering and film covering device 25 and a drip irrigation pipe laying device 28 behind the rotary tillage device 3. In this way, through the operation of the sugarcane ridge breaking and stubble leveling machine, agricultural management operations such as stubble leveling, ridge breaking and stump loosening, base fertilizer application, soil covering and film covering, and drip irrigation pipe laying can be completed simultaneously.

[0024] Furthermore, the main transmission shaft 6 transmits power to the rotary tilling tool of the rotary tilling device through the transmission box 26 and drives it to rotate.

[0025] Furthermore, an upper hanging ear 1.3 extending forward is provided at the front end of the frame 1 just above the universal coupling 7, and a lower hanging ear 1.4 extending forward is provided at the left and right sides of the front end of the frame 1 just below the universal coupling 7. The upper hanging ear 1.3 and the two lower hanging ears 1.4 are arranged in a herringbone shape and are all used for coupling with a matching tractor.

[0026] When the sugarcane ridge breaking and stubble leveling machine is used, the whole machine is firstly hooked to the rear of a matching tractor through the upper hook 1.3 and the lower hook 1.4, and the front end of the universal joint coupling 7 is connected to the PTO power output interface of the tractor. The matching tractor pulls the machine to move on the sugarcane field and provides driving power for the stubble leveling device 2 and the rotary tillage device 3 of the machine.

[0027] like Figure 5-Figure 7As shown, when the sugarcane ridge breaking and stubble leveling machine is stubble-leveling the sugarcane ratoons, the tractor wheel runs at the bottom of the ridge, the depth-limiting wheel 5 runs on the top of the ridge, and the profiling wheel 12 of the stubble leveling device 2 runs at the bottom of the ridge and stubbles the walking surface under the push of the elastic push mechanism, and the profiling wheel 12 drives the stubble leveling cutter disc 10 to float up and down accordingly according to the ups and downs of the ridge bottom. When working on flat ground, since the ridge has no obvious ups and downs, the profiling wheel 12 has no obvious up and down movement, and the stubble leveling device 2 will not float up and down significantly, and the cutting blade on the stubble leveling cutter disc 10 remains on the top surface of the ridge or at a certain depth of soil. When working on uphill terrain, the profiling wheel 12 remains pressed on the bottom of the ridge, and as the terrain rises, the front wheel frame 11 rises together with the profiling wheel 12, driving the sub-frame 8 components including the stubble leveling cutter disc 10 to rise, so that the cutting blade on the stubble leveling cutter disc 10 is still well maintained on the top surface of the ridge or at a certain depth of soil. When working on downhill terrain, due to the deadweight, the sub-frame 8 assembly including the stubble cutter disc 10 and the front wheel frame 11 moves downward as a whole until the contour wheel 12 remains pressed against the bottom of the furrow, so that the stubble cutter disc 10 also follows the lowering of the terrain, so that the cutting blades on the stubble cutter disc 10 can still be well maintained on the ridge top surface or at a certain depth of soil. Therefore, whether walking on flat land, uphill or downhill terrain, the cutting blades on the stubble cutter disc 10 can be well maintained on the ridge top surface or at a certain depth of soil, and there will be no phenomenon that the cutting blades are too deep in the soil due to uphill, thereby damaging the perennial roots of the sugarcane, or the cutting blades are too high from the ground due to downhill, resulting in the sugarcane stubble being too long.

[0028] It can be seen that the design of the stubble disc of the sugarcane ridging and stubble maker that can float in imitation of terrain can effectively solve the problem that the stubble disc 10 of the existing sugarcane perennial root stubble maker cannot well adaptively adjust the cutting depth when working on uphill and downhill terrains.

[0029] The above-mentioned figures are only typical embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
