[0068] The folding rotary tillage and ridging integrated machine is supported at the tail of a tractor through the suspension lifting system 101, and the ground clearance can be automatically adjusted according to the demand for driving or rotary tillage of the land; the engine output power is connected to the main transmission shaft 102 with a cross yoke structure at both ends through the output shaft of the gearbox, so that the power input demand of the rotary tillage device is guaranteed; as Figure 2 And Figure 3As shown, the main transmission shaft 102 drives the driven bevel gear 103a in the main reduction gearbox 104 through the tail end of the driving bevel gear 103. This main and driven bevel gear structure not only reduces the speed and increases the torque, but also changes the power transmission direction by 90 degrees. The driven bevel gear 103a is fixed on the horizontal shaft 1041 in the main reduction gearbox 104. The horizontal shaft 1041 penetrates and is supported at the upper end in the main reduction gearbox 104 through bearing structure.

The addendum circle diameter size of the third gear 1044 is 242 mm, the pitch circle diameter size is 220 mm, and the root circle diameter size is 190 mm. The spacing between the two adjacent groups of rotary tillage blades is 134.25 mm. This transmission structure and gear parameter design can guarantee the best transmission efficiency and reliability of the gear transmission in the main reduction gearbox 104.
[0070] As shown in the figure, Figures 2 to 5 The third gear 1044 in the main reduction gearbox 104 is connected with the left end of the left first rotary tillage blade shaft 110 and the right end of the right first rotary tillage blade shaft 111 through the setting of the inner spline structure, respectively, to drive the left first rotary tillage blade shaft 110 and the right first rotary tillage blade shaft 111 to rotate synchronously. The inner side of the left end spline shaft of the left first rotary tillage blade shaft 110 and the inner side of the right end spline shaft of the right first rotary tillage blade shaft 111 are supported at the lower end position of the main reduction gearbox 104 through the setting of bearing structure, respectively. The spline shaft and support bearing structure at the shaft end of the left first rotary tillage blade shaft 110 and the right first rotary tillage blade shaft 111 are sealed through the setting of the rubber sealing cover 111a, to guarantee the working reliability and service life, etc. The other end of the left first rotary tillage blade shaft 110 and the right first rotary tillage blade shaft 111 is supported on the blade shaft support 112a through the setting of bearing structure, respectively. The blade shaft support 112a is fixed on the two ends of the first cross beam 105a and the second cross beam 105c through bolts, respectively. The first cross beam 105a, the second cross beam 105c and the two blade shaft supports 112a form part of the rack structure.
[0071] When the driving bevel gear 103 drives the driven bevel gear 103a to rotate, the coaxial first gear 1042 is driven to rotate, and then the second gear 1043 and the third gear 1044 drive the left first rotary tiller shaft 110 and the right first rotary tiller shaft 111 to rotate synchronously.
[0072] As shown in Figure 2 and Figure 3 , the main reduction gearbox 104 is fixed and supported by bolt structure at the middle position between the first cross beam 105a and the second cross beam 105c, and is arranged in a symmetrical structure. The cross shaft 1041 in the main reduction gearbox 104 is connected with the right transmission shaft 107 and the left transmission shaft 109 through the cross yoke 1071 and the cross yoke 1091 structure respectively. The right end of the right transmission shaft 107 is connected with the connecting shaft 202. The connecting shaft 202 penetrates the bearing support plate 201 through the bearing support 203, and the left end of the bearing support 203 is fixed on the bearing support plate 201 by bolt connection. The bearing support plate 201 is fixed longitudinally on the first cross beam 105a and the second cross beam 105c, which ensures the stable support of the right transmission shaft 107 and the connecting shaft 202 during power transmission. The right end of the connecting shaft 202 is a connector 204, the right end of which is connected with a spline shaft 205. The spline shaft 205 is supported at the upper end in the first secondary reduction gearbox 106 through bearing structure arranged at both ends.

The pin shaft 1062a is fixed at the middle position of the two sides of the first secondary reduction gearbox 106. The fifth gear 1062 meshes with the sixth gear 1063.
[0073] As shown in Figures 1 to 4 , the sixth gear 1063 in the first secondary reduction gearbox 106 is connected with the spline shaft at the left end of the left second rotary tiller shaft 112 through the inner spline structure, which drives the left second rotary tiller shaft 112 to rotate. The right end of the left second rotary tiller shaft 112 is supported on the cutter shaft support 112a through bearing structure. The cutter shaft support 112a is fixed on the outer end of the first suspension beam 105b by bolt. The first secondary reduction gearbox 106 and the second secondary reduction gearbox 108 are fixed and supported by bolt structure at the inner end position of the first suspension beam 105b and the suspension beam 105b.
[0074] When the driving bevel gear 103 drives the driven bevel gear 103a to rotate, the cross shaft 1041 is driven to rotate. The power drives the fourth gear 1061 in the first secondary reduction gearbox 106 through the cross yoke 1071, the right transmission shaft 107, the connecting shaft 202, the connector 204, the spline shaft 205, and then drives the left second rotary tiller shaft 112 to rotate synchronously through the fifth gear 1062 and the sixth gear 1063. Figure 6As shown, multiple rotary tiller blades 114 are arranged at equal intervals on the two first rotary tiller shafts and the two second rotary tiller shafts.
[0075] Since the rotary tiller is arranged in a symmetrical structure, the power is transmitted to the lower end gear path in the second sub-reduction box 108 through the left transmission shaft 109 and is consistent with the lower end gear path in the first sub-reduction box 106 through the right transmission shaft 107, and finally drives the left second rotary tiller shaft 112 and the right second rotary tiller shaft 113 to rotate synchronously.
[0076] The rotary tiller adopts a double-shaft transmission scheme, which can guarantee the power performance and stability of the left second rotary tiller shaft 112 and the right second rotary tiller shaft 113 during rotary tillage of the land, and avoid problems such as insufficient power at the end of the rotary tiller shaft and poor balance during single-shaft power transmission.
[0077] As shown in Figure 7 the right end of the connecting shaft 202 is a left connecting disc 2041 of the connector 204, the inner end of the left connecting disc 2041 (close to the side of the connecting shaft 202) is supported by being arranged in the bearing support plate 201, a cylindrical bearing is arranged in the bearing support plate 203 to guarantee the stability of the left connecting disc 2041 during rotary connection, the right connecting disc 2042 of the connector 204 is fixedly connected to the left end of the spline shaft 205, and the spline shaft 205 penetrates and is supported at the upper end in the first sub-reduction box 106 through the bearing structure arranged at both ends.
[0078] As shown in Figure 7 , Figure 8 the connector 204 is connected by a plurality of mushroom nails 206 (arranged uniformly on the disc in a circumferential direction) arranged on the circumference of the left connecting disc 2041 and the right connecting disc 2042, the mushroom nails 206 are limited in the assembly position by the assembly nut at the outer end surface of the left connecting disc 2041, a rubber ring 2061 is arranged at the joint of the mushroom nail 206 and the right connecting disc 2042 to alleviate the impact when the left connecting disc 2041 and the right connecting disc 2042 are connected, guaranteeing the smooth combination, the right connecting disc 2042 is provided with a cylindrical hole corresponding to the mushroom nail 206, and the inner end surface (close to the side of the left connecting disc 2041) of the cylindrical hole is provided with a circular chamfer, facilitating the matching connection of each mushroom nail 206 and the corresponding cylindrical hole, when the connector 204 is in a connected state, the mushroom nail 206 guarantees the reliability of the left connecting disc 2041 and the right connecting disc 2042, so that the right connecting disc 2042 rotates synchronously with the left connecting disc 2041, and the right connecting disc 2042 drives the spline shaft 205 to rotate synchronously by being arranged with an internal spline; when the right connecting disc 2042 of the connector 204 is folded upwards with the spline shaft 205, it can be automatically separated from the mushroom nail 206, and the design structure of the connector 204 guarantees the stability and reliability of the automatic separation or automatic connection of the left connecting disc 2041 and the right connecting disc 2042.
[0079] As shown in Figure 9 , Figure 10 , it is a folding connection structure of rotary cultivator, the support shaft 301 is provided with a sleeve 302 outside, the sleeve 302 can rotate around the support shaft 301, the two ends of the sleeve 302 are respectively supported by the front and rear two first support plates 303 and two second support plates 303a fixed at the two ends of the first cross beam 105a and the second cross beam 105c, the front and rear two third support plates 304 and two fourth support plates 304a fixed at the other end of the two first suspension beams and the other end of the two second suspension beams, the other end of the two first support plates 303 and the two third support plates 304 overlap each other to form a set of triangular structure, the other end of the two second support plates 303a and the two fourth support plates 304a overlap each other to form a set of triangular structure, the front and rear two pairs of first support plates 303, second support plates 303a, third support plates 304 and fourth support plates 304a can rotate around the sleeve 302, the two ends of the support shaft 301 extend out of a length relative to the sleeve 302, the front end (close to the tractor end) is used for mounting a set of connecting rods 305, the lower end sleeve 305a of the set of connecting rods 305 is assembled on the front end of the support shaft 301 through the needle bearing and can freely swing around it, the upper end sleeve 305b of the connecting rod 305 is assembled on the pin shaft 306 through the needle bearing and can freely swing around it, the piston rod 307a and the piston rod 308a of the second hydraulic cylinder 307 and the first hydraulic cylinder 308 assembled on the pin shaft 306 are arranged in intervals, the upper end of the piston rod 307a and the piston rod 308a is hinged on the pin shaft 306 through the circular support ring and can freely swing around it, the lower end of the second hydraulic cylinder 307 and the first hydraulic cylinder 308 is hinged on the first cross beam 105a through the support pin shaft and support seat structure and can swing around the support pin shaft.
[0080] As shown in Figure 19 , when the tractor drives on the road, the two first suspension beams 105b at both ends of the rotary cultivator are folded and stored through the hydraulic system, the oil tank in the hydraulic system is connected to the upper oil port 3071 and the lower oil port 3072 of the second hydraulic cylinder 307 (the upper oil port 3081 and the lower oil port 3082 of the first hydraulic cylinder 308) through the oil pipe respectively, as shown in Figure 11As shown, when the hydraulic system is started to fold the rotary cultivator, the hydraulic oil in the oil tank flows into the upper end oil port 3071 of the second hydraulic cylinder 307 and the upper end oil port 3081 of the first hydraulic cylinder 308 through the oil pipe, and as the oil flows into the upper chambers of the second hydraulic cylinder 307 and the first hydraulic cylinder 308, the oil pressure in the upper chambers continuously increases, urging the piston rods 307a and 308a to compress into the hydraulic cylinders. At the same time, the oil in the lower chambers of the second hydraulic cylinder 307 and the first hydraulic cylinder 308 flows back to the oil tank through the oil ports 3072 and 3082, and under the action of the pressure difference between the upper and lower chambers of the hydraulic cylinders, the piston rods are compressed relative to the hydraulic cylinders. The first suspension beam 105b at both ends changes in compression relative to the piston rods 307a and 308a, and the connecting rod 305 rotates upward by a certain angle around the support shaft 301, together with the second hydraulic cylinder 307 and the first hydraulic cylinder 308 and the piston rods 307a and 308a. The structural parameters of the second hydraulic cylinder 307 and the first hydraulic cylinder 308 and the piston rods 307a and 308a are matched to satisfy that the first suspension beam 105b can be folded upward by 180 degrees, until the cutter shaft support 112a at the outer end of the first suspension beam 105b falls on the support assembly 101a. In this process, the left connecting disc 2041 and the right connecting disc 2042 of the connector 204 are automatically separated.
[0081] When the tractor is plowing the land in the field, the first suspension beam 105b at both ends of the rotary cultivator is unfolded by controlling the hydraulic system. The oil tank in the hydraulic system is connected to the upper oil port 3071 and the lower oil port 3072 of the second hydraulic cylinder 307 (the upper oil port 3081 and the lower oil port 3082 of the first hydraulic cylinder 308) through the oil pipe, as shown in the figure. Figure 11 As shown, when the hydraulic system is started to unfold the rotary cultivator, the hydraulic oil in the oil tank flows into the lower oil ports 3072 and 3082 of the second hydraulic cylinder 307 and the first hydraulic cylinder 308 through the oil pipe, and as the oil flows into the lower chambers of the second hydraulic cylinder 307 and the first hydraulic cylinder 308, the oil pressure in the lower chambers continuously increases, urging the piston rods 307a and 308a to stretch outward. At the same time, the oil in the upper chambers of the second hydraulic cylinder 307 and the first hydraulic cylinder 308 flows back to the oil tank through the upper oil ports 3071 and 3081, and under the action of the pressure difference between the upper and lower chambers of the hydraulic cylinders, the piston rods are stretched outward relative to the hydraulic cylinders. The first suspension beam 105b at both ends changes in extension relative to the second hydraulic cylinder 307 and the first hydraulic cylinder 308, and the connecting rod 305 rotates downward by 180 degrees around the support shaft 301, together with the second hydraulic cylinder 307 and the first hydraulic cylinder 308, until it returns to the initial unfolded position of the rotary cultivator. In this process, the cylindrical hole on the right connecting disc 2042 of the connector 204 automatically matches and connects with the mushroom peg 206 of the left connecting disc 2041, realizing the synchronous rotation of the connecting shaft 202 and the spline shaft 205.

This structure ensures that the plowing direction of the plow head of the plow 507 always faces the front direction when the plow 507 appears to be deflected left and right.
[0088] To realize the equal-interval adjustable function between the ten groups of plows 507, an interval adjusting device is arranged to adjust the interval of the ten groups of plows 507. In this embodiment, the interval adjusting device includes three groups of stepping motors and screw rod mechanisms, each group of motor is controlled by an independent controller, as shown in Figures 15 to 17 The six groups of plows 507 of the main beam 501 are controlled and adjusted by the main motor 601 and the first screw rod 602, and the two groups of plows 507 on the third suspension beam 501a are controlled and adjusted by the side motor 603 and the second screw rod 604.

A plurality of first support pins 703 are arranged at both ends of the torsion bar 701, and the distances between the support pins are arranged in a certain proportional relationship, that is, the distances from the pin 702 to each first support pin 703 are increased in this proportional relationship.
[0091] When the controller controls the main motor 601 to work, the main motor 601 drives the first screw rod 602 to rotate in a certain direction, the first screw rod 602 promotes the main support plate 6013 to rotate to the outer end of the screw rod, at this time, due to the sleeve 6012 and the second support pin 5061, the sleeve 6014 and the support pin, and the constraint of the length of the torsion bar 701, the first screw rod 602 promotes the main support plate 6013 to rotate clockwise through a certain angle around the pin 702 (at the same time, the first screw rod 602 drives the main motor 601 to rotate clockwise around the second support pin 5061), the inner end of the push rod 703a (close to the end of the torsion bar 701) is supported on the first support pin 703 through the setting of the eyelet and can swing around it, the first support pin 703 promotes the push rod 703a to rotate through a corresponding angle in the clockwise direction, the outer end of the push rod 703a is fixed on the outer end cylindrical pin 5083 on the outer end of the connecting rod mechanism 508, that is, the push rod 703a promotes the corresponding connecting rod mechanism 508 to rotate through a corresponding angle in the clockwise direction, and the angle corresponds to the realization of equal interval change between each group of plows.
[0092] As shown in Figure 13 , the side motor 603 and the main motor 601 have the same fixed connection structure, which is fixed and constrained on one side of the second square longitudinal beam 505 through bolts, support plates, sleeves and support pins, the output end of the side motor 603 is connected with the second screw rod 604, the side support plate through which the second screw rod 604 penetrates is assembled on the support pin 706 through the sleeve and can swing around it, the support pin 706 is fixed on the inner side connecting rod 5081 at a position slightly forward of the middle, the inner end of the second push rod 706a (close to the end of the torsion bar 701) is supported on the support pin 706 through the setting of the eyelet and can swing around it, and the outer end of the second push rod 706a is fixed on the support pin 707 at the middle position of the outermost group of connecting rods 5081.
[0093] When the controller controls the main motor 601 to work, the other two controllers inform the control of the side motor 603 to rotate in the same direction, the second screw rod 604 promotes the side support plate to rotate through a certain angle in the corresponding direction around the support pin 706, the support pin 706 drives the second push rod 706a to promote the support pin 707 on the outermost group of connecting rod mechanisms 508 to rotate through a corresponding angle in the corresponding direction, and the fixed points of the support pin 706 and the support pin 707 on the connecting rod 5081 guarantee that when the second screw rod 604 rotates, the interval between the outermost two groups of plows is always the same as the interval between the middle six groups of plows 507, and the consistency of the interval of rotary plowing and ridging is guaranteed.
[0094] When it is necessary to adjust the interval between the plows, the main motor 601 and the side motor 603 are controlled to rotate in the opposite direction at the same time, so that the initial interval setting can be restored, and the main motor 601 and the side motor 603 in the device are all stepping motors.
[0095] As shown in Figure 19As shown, the cover plate 401 and the tail plate 402 on the rotary tillage and ridging integrated machine effectively prevent soil splashing when the rotary tiller rotates the soil, the tail plate 402 can adjust the inclination angle relative to the ground through the lifting pull rod 403 (two-way hydraulic cylinder structure), and the tail plate 402 can also play a role in leveling and loosening the soil; the limiting wheel 404 is fixed to the front end of the cross beam 105 through the adjusting support 405, and the ground clearance of the limiting wheel 404 can be adjusted by adjusting the bolt hole installation position of the adjusting support 405, thereby effectively adjusting the rotary tillage depth of the rotary tiller in the soil; the triangular plow 406 arranged below the front side of the main reduction box 104 and the triangular plow 406 below the front side of the first auxiliary reduction box 106 and the second auxiliary reduction box 108 effectively compensate for the rotary tillage gap when the rotary tillage blade is missing in the position of the reduction box, and play a role in soil loosening and full coverage.
[0096] The rollers 801 and 803 are supported at the rear of the rotary tillage and ridging integrated machine through the support frame 802 welded on the main beam 501 and the third suspension beam 501a, and level and compact the ridge plane after the plow 507 is ridged.
[0097] When the engine output power drives the main transmission shaft 102 through the transmission device to drive the driving bevel gear 103 to rotate, the driving bevel gear 103 drives the driven bevel gear 103a in the main reduction box 104 to rotate, thereby driving the first gear 1042 to rotate, and finally driving the left first rotary tillage blade shaft 110 and the right first rotary tillage blade shaft 111 to rotate synchronously through the second gear 1043 and the third gear 1044, and driving the rotary tillage blades on the left first rotary tillage blade shaft 110 and the right first rotary tillage blade shaft 111 to penetrate into the soil for loosening.
[0098] At the same time, the driving bevel gear 103 drives the driven bevel gear 103a in the main reduction box 104 to rotate, thereby driving the cross shaft 1041 to rotate, and the cross shaft 1041 drives the gear 1061 in the first auxiliary reduction box 106 to rotate through the right transmission shaft 107, the connecting shaft 202, the connector 204, and the spline shaft 205, and finally drives the left second rotary tillage blade shaft 112 (113) to rotate synchronously through the gear 1062 and the gear 1063, and drives the rotary tillage blades on the left second rotary tillage blade shaft 112 (113) to penetrate into the soil for loosening.
[0099] At the same time, the plow 507 fixed on the main beam 501 and the third suspension beam 501a realizes land ridging at the rear of the rotary tillage land, and the rollers 801 and 803 level and compact the ridging plane.
[0100] When the rotary tillage and ridging integrated machine is not working, the limiting wheel 404 is lifted through the lifting pull rod 403 (two-way hydraulic cylinder structure) to the position of the main beam 501, and the limiting wheel 404 is fixed to the front end of the cross beam 105 through the adjusting support 405. Figures 9 to 11The hydraulic system shown realizes folding storage, under the action of the hydraulic system, the second hydraulic cylinder 307 and the first hydraulic cylinder 308 are compressed relative to the piston rod 307a and the piston rod 308a, so that the first suspension beam 105b can be folded upward by 180 degrees until the cutter shaft support 112a at the outer end of the first suspension beam 105b falls on the support assembly 101a, and the folding process is completed. Figure 19 As shown, in this process, the left connecting disc 2041 and the right connecting disc 2042 of the connector 204 are automatically separated, and the rotary tillage mechanism and the ridging mechanism are folded together.
