Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery for saline-alkali land conditioning. More precisely, the present invention relates to a rotary burying integrated machine for applying a conditioner for shallow loosening and trenching of saline-alkali land. Background Art

[0002] Existing machines for improving saline-alkali land have various defects: A subsoiler improves the soil structure by breaking the plow sole, but the operation process may damage the soil structure, resulting in a decline in fertility and consuming a large amount of energy. Drainage machines reduce the salt accumulation in the soil by draining and washing salts, but their cost is relatively high, and most water resources are scarce in saline-alkali areas. Experiments have shown that applying an appropriate amount of chemical conditioner has a significant effect on improving saline-alkali land. However, the existing conditioner application machines have poor precision in precise application. Over-application will instead be counterproductive, and the degree of full mechanization in the application process is not high. Only the process of applying the conditioner can be achieved, and processes such as trenching and burying still need to be completed manually, with a still relatively high labor intensity. Therefore, it is of great significance to invent a mechanized machine for precisely applying a conditioner for trenching, spreading, and rotary burying. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that there are problems in the prior art such as low mechanization degree in applying the conditioner and low control precision of the application amount. The present invention provides a rotary burying integrated machine for applying a conditioner for shallow loosening and trenching of saline-alkali land.

[0004] The rotary burying integrated machine for applying a conditioner for shallow loosening and trenching of saline-alkali land includes a fertilizer tank assembly, a frame, a power system, a hydraulic system, and working components.

[0005] The said frame is the base of the rotary burying integrated machine for applying a conditioner for shallow loosening and trenching of saline-alkali land. The fertilizer tank assembly is located at the upper part of the frame and is fixed to the frame by bolts. The power system includes a corrugated disc power drive kit, a conditioner auger power drive kit, and a soil-agent stirring vertical shaft power drive kit, which are respectively arranged on the front side, the upper side, and the right side of the frame. Two regulating valves in the hydraulic system are located on the side support rib of the left fertilizer tank, and the cooling fan is located on the side support rib of the right fertilizer tank. The left and right side support ribs are located above the frame and below the fertilizer tank, and are fixed to the fertilizer tank and the frame by bolts. The hydraulic oil pot is located outside the side plate of the conditioner stirring area structure plate and is fixed to the side plate by bolts. Two ground wheels and their hydraulic telescopic rods are located on both sides of the frame and are fixed by pins. The working components include a corrugated disc: which is connected to the corrugated disc power drive kit and is arranged on the front side of the frame; a trench digging shovel: which is fixed to the bottom of the frame by bolts; a stirring vertical shaft: which is matched with the soil-agent stirring shaft power drive kit at the bottom of the frame; a rear ground wheel: which is fixed to the rear side of the frame by bolts through a rear ground wheel bracket.

[0006] The described fertilizer box assembly is a welded component with a length of 750 mm, a width of 665 mm, and a thickness of 3 mm. The box assembly includes 3 conditioner stirring area structural plates, 1 fertilizer box support plate, 2 fertilizer box side support rib plates, 2 conditioner feeding area structural plates, a spiral auger, a driven sprocket, and a rotational speed sensor. The connection method between components such as the conditioner stirring area structural plates, fertilizer box support plate, and fertilizer box side support rib plates adopts a special evenly distributed through-hole and bolt connection design, which not only ensures the firmness of the connection but also facilitates disassembly and maintenance. Compared with other existing material boxes, this connection method is more reasonable and innovative.

[0007] The described 3 conditioner stirring area structural plates are located at the upper part of the frame and are divided into a front plate, side plates, and a rear plate. A communication hole is opened on the front plate, and 6 through-holes are evenly distributed around the communication hole of the front plate and are bolted to the support plate of the feeding area structural plate. 12 through-holes are evenly distributed at the ends of the side plates and are bolted to the end cover of the front plate. 10 through-holes are evenly distributed on both sides inside the side plates and are bolted to the 2 fertilizer box side support rib plates. 18 through-holes are evenly distributed at the tail of the side plates and are bolted to the end cover of the rear plate and the fertilizer box support plate respectively. An axial hole is opened on the rear plate, and 6 through-holes are evenly distributed around the axial hole and are bolted to the sensor support and the bearing seat respectively.

[0008] A communication hole is opened on the described front plate, which is an arched hole composed of an arc with a radius of 70 mm and a transition arc with a radius of 100 mm. This hole enables the auger to rotate the conditioner in the stirring area into the feeding area, making the stirring area communicate with the feeding area.

[0009] An axial hole is opened on the described rear plate. The axial hole is oval, with two semi-circles with a radius of 20 mm at the upper and lower parts and a straight line with a length of 10 mm in the middle for transition. This hole connects the feeding area with the driven sprocket of the transmission component, facilitating power transmission.

[0010] 6 through-holes are opened on the described rear plate, which are respectively 2 hexagonal head bolts with a diameter of 8 mm and a length of 16 mm, tightened and fixed with a nut with a diameter of 8 mm to the sensor support, and 4 hexagonal head bolts with a diameter of 10 mm and a length of 30 mm, tightened and fixed with a nut with a diameter of 10 mm to the bearing support.

[0011] The described 1 fertilizer box support plate is located above the tail of the frame and below the tail of the side plate of the stirring area structural plate, and is fixed to the frame and the side plate by bolts, thereby increasing the working stability of the fertilizer box and reducing the longitudinal strain of the fertilizer box under long-term operation.

[0012] The two side support ribs of the fertilizer box are divided into the left support rib and the right support rib. They are located above the frame and below the side plate of the mixing area structure plate, and are fixed to the frame and the side plate by bolts. Two circular holes with a diameter of 20 mm are opened on the left support rib for adjustment and assembly, and four through holes are opened on the right support rib. The left and right support ribs support the fertilizer box to reduce the generation of lateral stress and increase the working stability.

[0013] Four through holes are opened on the right support rib described above and are fixed to the cooling fan by bolts.

[0014] The two conditioner feeding area structure plates are located above the front part of the frame and in front of the front plate of the conditioner mixing area structure plate. They are divided into the main board and the support board and are fixed by bolts. The main board is a fence-type structure and is a welded part formed by welding three plates together. A shaft hole is opened on the support board to cooperate with the auger shaft, and 15 through holes are opened on the main board and are fixed to the frame and the bearing seat by bolts respectively. An arched hole (the same as the hole on the front plate cover of the mixing area) is opened on the support board to allow the auger blade to spin out, and six through holes are opened on the support board and are fixed to the front plate of the mixing area by bolts.

[0015] Fifteen through holes are opened on the main board of the feeding area. Eight through holes are fixed to the frame by bolts, four through holes are fastened to the bearing seat by bolts, and three through holes are fastened to the frame end cover by bolts.

[0016] Six through holes are opened on the support board and are fastened to the frame by bolts.

[0017] A spiral auger is located inside the fertilizer box assembly and inside the conditioner feeding area. Its length is 1040 mm, inner diameter is 35 mm, outer diameter is 125 mm, pitch is 130 mm, and blade thickness is 3 mm. The first auger shaft is connected to the driven sprocket by a square seat bearing with a flat key, and a threaded hole is opened on the sprocket bushing. A hexagon head bolt with a diameter of 8 mm and a length of 30 mm is screwed in to reinforce the connection between the flat key and the auger shaft and reduce the loss during power transmission. The blade shape of the conditioner auger adopts a special involute design. This design can make the conditioner distribute more evenly during transportation, and with the gradual change of the pitch, it can effectively control the transportation speed of the conditioner and avoid blockage. It is significantly different from the common equal pitch and straight blade design in the existing augers and can better meet the requirements of conditioner spreading.

[0018] The flat key is a common type A key with dimensions of 8×7×28.

[0019] The number of teeth of the driven sprocket is 40, the pitch is 15.87 mm, and the roller diameter is 10 mm.

[0020] The described frame is the base of the implement and is a combined casting. The various support plates are welded together. The frame is designed as a double-layer structure to ensure the stability of fixing with other components. The upper layer of the frame is mainly used to support the fertilizer tank assembly, and it is designed with a special reinforcing rib structure that can withstand the dynamic load of the fertilizer tank assembly during operation. The lower layer of the frame is fixed to components such as the corrugated disc motor support and the rear ground wheel support through lead screws. This lead screw connection method can precisely adjust the position and height of each component to adapt to different agronomic requirements. Compared with the traditional frame structure connected by simple bolts, it has higher flexibility and adaptability. It is fixed to the ditching shovel base and the stirring vertical shaft through bolts, and 1 support seat for the feeding area is fixed on the lower layer of the support through bolts. 2 ground wheel connecting rods are welded on both sides of the frame. 3 suspension brackets are welded on the front side of the frame and are connected to the tractor through a three-point suspension method. The welding position is 150 mm away from the front end of the frame, and the load-bearing area of the suspension bracket adopts a triangular reinforcing rib design.

[0021] The described 1 support seat for the feeding area has a hollow structure inside, and the conditioner in the feeding area reaches the ditching shovel through the support seat for the feeding area and then falls into the soil.

[0022] The described corrugated disc power drive kit consists of a motor support, a corrugated disc hydraulic motor, a coupling, a bevel gear direction changer, a spline shaft, and a spline shaft sleeve.

[0023] The described motor support is located on the front side of the frame and is an integrally welded component. A hydraulic motor is installed on the side plate of the motor support. The power transmitted by the hydraulic motor is transmitted to the bevel gear direction changer through the coupling to change the direction, and the spline shaft inside the right-angle box is matched with the spline shaft sleeve on the corrugated disc, causing the corrugated disc to rotate.

[0024] The described hydraulic motor is a BMM-50 series hydraulic motor, with a flow rate of 20 L / min and a continuous output power of 1.8 KW, which is estimated to meet the requirements of the cutter disc for mowing grass.

[0025] The described conditioner auger drive kit consists of a motor mounting plate, a 12V DC motor, a driving sprocket, a driven sprocket, and a motor auger.

[0026] The described motor mounting plate is located on the upper front side of the frame and is an integrally welded component. The driving sprocket is installed on the motor shaft, and the power is transmitted between the driving sprocket and the driven sprocket through a chain. The rotation of the driven sprocket drives the auger to rotate and work.

[0027] The described driving sprocket has 10 teeth, a pitch of 15.87 mm, and a roller diameter of 10.16 mm.

[0028] The described stirring vertical shaft power drive kit consists of a stirring vertical shaft hydraulic motor, a coupling, a bevel gear direction changer, an outer spherical bearing with a convex platform circular seat, a stirring shaft tube, and a cutter shaft flange.

[0029] The described vertical stirring hydraulic motor is installed on the right side of the frame and fixed to the frame by bolts. The power transmitted by the hydraulic motor passes through a coupling, and the bevel gear direction-changing box turns to the stirring shaft tube. The power transmitted by the stirring shaft tube reaches the cutter shaft flange through the spherical plain bearing with a bossed circular seat. The cutter shaft flange is fixed to the vertical stirring shaft by bolts, causing the vertical stirring shaft to rotate and mix the soil and conditioner.

[0030] The described spherical plain bearing with a bossed circular seat has a good self-aligning function, ensuring the precise operation of the vertical stirring shaft.

[0031] The described hydraulic system includes 2 regulating valves, 1 hydraulic oil pot, 1 cooling fan, and 2 ground wheel hydraulic telescopic rods.

[0032] The described 2 regulating valves include a corrugated disc speed regulating valve and a vertical stirring shaft regulating valve, which are located on the support rib on the left side of the fertilizer box. The internal spool structure and flow control method of the corrugated disc speed regulating valve and the vertical stirring shaft regulating valve in the hydraulic system are specially designed to accurately control the flow rate of the hydraulic oil, thereby achieving precise adjustment of the speeds of the corrugated disc and the vertical stirring shaft.

[0033] The described 1 hydraulic oil pot is fixed to the support rib on the right side of the fertilizer box by bolts. The capacity of the hydraulic oil pot (6) and the performance parameters of the hydraulic oil are also optimized according to the working requirements of this machine, ensuring the stability and reliability of the entire hydraulic system under long-term and high-intensity operations.

[0034] The air duct of the described cooling fan is arranged in parallel with the outlet pipe of the hydraulic oil pot, increasing the heat dissipation efficiency by 40%.

[0035] The described corrugated disc speed regulating valve adjusts the speed of the corrugated disc by changing the flow rate of the hydraulic motor in the power drive kit of the corrugated disc, thereby changing the motor speed.

[0036] The described vertical stirring shaft regulating valve adjusts the speed of the vertical stirring shaft by changing the flow rate of the hydraulic motor in the power drive kit of the soil conditioner vertical stirring shaft, thereby changing the motor speed.

[0037] The described 1 hydraulic oil pot is located on the right side plate of the fertilizer box and is fixed to the right side plate of the fertilizer box by bolts. The hydraulic oil in it is regulated by the regulating valve to provide power for the corrugated disc hydraulic motor and the vertical stirring shaft hydraulic motor.

[0038] The described 1 cooling fan is located on the support rib on the right side of the fertilizer box and is fixed to the support rib on the right side of the fertilizer box by bolts. During the operation of the hydraulic system, a large amount of heat is generated when the hydraulic oil is transmitted to the hydraulic motor for rotation and during its movement in the pipeline. Therefore, the cooling fan is connected to dissipate heat during the operation.

[0039] The two ground wheel hydraulic telescopic rods are located on both sides of the frame and are fixed to the frame by pin shafts. The telescopic stroke of the ground wheel hydraulic telescopic rod is 200 mm, which cooperates with the spring to achieve adaptive adjustment for ground undulations, and completes the elastic expansion and contraction of the ground wheel on uneven ground. Each hydraulic telescopic rod is provided with connecting holes, which are respectively connected to the corresponding connecting holes on the other side to form a closed-loop space, and the hydraulic oil forms a certain pressure inside, so that it can adapt to working at different heights.

[0040] The corrugated disc working component is installed on the front side of the frame and consists of a corrugated disc, a spline shaft sleeve, a right-angle box, a spline shaft, and a gasket. The corrugated disc is assembled on the spline shaft sleeve, and the spline shaft is nested and rotates in the spline shaft sleeve to drive the corrugated disc to rotate. A gasket is added at the front end of the shaft sleeve and fastened with bolts. During the working process of the machine, the corrugated disc plays a role in crushing soil lumps, performing preliminary soil loosening and crushing, and facilitating subsequent ditch opening and material feeding operations.

[0041] The ditch-opening shovel working component is installed on the lower side of the frame and directly behind the corrugated disc, and is fixed to the frame by bolts. It consists of components such as a ditch-opening shovel base, a ditch-opening shovel tip, a ditch-opening shovel curved surface, and a soil dividing shovel. The ditch-opening shovel base forms the two sides and the rear side of the ditch-opening shovel working component. The upper part of the front side is the soil dividing shovel, the curved surface in the middle area of the front side is the ditch-opening shovel curved surface, and the pointed area extending outward at the lower end is the ditch-opening shovel tip. Each part is connected together by welding.

[0042] The inside of the ditch-opening shovel base is a hollow structure and is connected to the conditioner feeding area of the fertilizer box mentioned above. The conditioner is fed through the hollow area inside the ditch-opening shovel base to the soil.

[0043] The ditch-opening shovel tip first contacts the soil and cuts it, then the ditch-opening shovel curved surface transports the soil to both sides, and finally the soil dividing shovel effectively levels the ground surface, eliminating the unevenness of the ground surface and creating good conditions for the subsequent operation of mixing soil and conditioner.

[0044] The stirring vertical shaft working component is located on the lower side of the frame and directly behind the ditch-opening shovel. It is a combined casting and is fixed to the cutter shaft flange by bolts. It consists of components such as a stirring shaft sleeve, a blade plate, a vane plate, and a circular ring plate.

[0045] The length of the stirring shaft sleeve is 300 mm, and 3 circular ring plates are evenly welded on the stirring shaft sleeve from top to bottom. The diameters of the circular ring plates gradually decrease, and the diameter of the lower plate is the smallest, which are 150 mm, 110 mm, and 80 mm respectively. 6 through holes are opened on the upper plate at the end of the stirring shaft and are fixed to the cutter shaft flange by bolts.

[0046] The described blade plates are distributed on the side of the vertical mixing shaft at 120° intervals and welded together. Since the diameters of the circular plates on the mixing shaft tube gradually decrease, a structure of "narrow at the bottom and wide at the top" is formed when installing the blade plates. Such a structure facilitates the full mixing of the conditioner with the soil in the area where the surface salinization of the soil is severe during soil mixing. At the same time, due to the large stress in the deep layer of the soil, reducing the contact area between the bottom plate and the soil improves the mixing ability and reduces energy consumption.

[0047] The described blade plates are evenly welded on the blade plates, and each blade plate has 5 blade plates with a spacing of 62 mm. The blade shape is a 90° sector shape. Tests have shown that when the vertical mixing shaft rotates counterclockwise at this size, the side of the blade plate can cut large soil chunks into pieces to fully mix with the conditioner.

[0048] The described rear ground wheel working component is located at the rear side of the frame and directly behind the vertical mixing shaft. It consists of a rear ground wheel, a rear ground wheel support, and a spring.

[0049] The described rear ground wheel is in the shape of a circular empty barrel, and there is a rear ground wheel support shaft inside, which is fixed to the empty barrel by bolts. When the machine moves forward, it drives the rear ground wheel to move forward to complete the operation of covering the soil.

[0050] One side of the described rear ground wheel support is fixed to the frame by a lead screw, and the other side is fixed to the rear ground wheel shaft by a nut.

[0051] The described spring is connected to the rear ground wheel support by a pin shaft, and the other side is suspended at the tail of the frame, thus ensuring that the rear ground wheel can complete the operation of covering and burying the soil at different heights.

[0052] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0053] 1. The fertilizer box support plate added in the fertilizer box assembly is fixed to the side support ribs on both sides of the fertilizer box and the box body by bolts, avoiding the stress concentration in the horizontal or vertical direction during the long-term operation of the fertilizer box, which may cause the fertilizer box to tilt and ensuring the working stability of the fertilizer box.

[0054] 2. The adjustment valve can separately control the rotation speeds of the corrugated disk and the vertical rotating shaft, so that the machine is not limited to working at the same rotation speed. In different working environments, better effects of improving saline-alkali land can be achieved by matching corrugated disks and vertical rotating shafts with different rotation speeds.

[0055] 3. The rotation speed sensor at the end of the auger shaft can accurately measure the rotation speed of the auger, and the amount of material discharged can be obtained according to the traveling speed of the machine. By adjusting the change of the traveling speed, the amount of material discharged can be accurately controlled.

[0056] 4. The blades on the mixing shaft rotate in multiple layers to cut the soil, ensuring that the soil blocks are within a small range and maximizing the mixing with the conditioner.

[0057] 5. The installation position of the blade plate on the stirring vertical shaft is inclined at a certain angle, which is beneficial to reducing the longitudinal stress of the soil received and increasing the stirring efficiency. Brief Description of the Drawings

[0075] A communication hole is opened on the front plate (1) described above, which is an arched hole composed of an arc with a radius of 70 mm and a transition arc with a radius of 100 mm. This hole enables the auger (4) to spin the conditioner in the mixing zone into the blanking zone, making the mixing zone communicate with the blanking zone.

[0076] A shaft hole is opened on the rear plate (3) described above.

[0079] The two side support ribs (7)(11) of the fertilizer box are divided into a left support rib and a right support rib. They are located above the frame (B) and below the side plate (2) of the conditioner mixing zone structure plate, and are fixed to the frame (B) and the side plate (2) by bolts. Two circular holes with a diameter of 20 mm are opened on the left support rib (11) for assembling with the regulating valve (12), and 4 through holes are opened on the right support rib (7).

The head auger shaft (4) is connected to the driven sprocket (10) by a square seat bearing (17) with a flat key (16). A threaded hole is opened on the sprocket bushing, and a hexagonal head bolt (15) with a diameter of 8 mm and a length of 30 mm is screwed in to reinforce the connection between the flat key (16) and the auger shaft (4), reducing the loss during power transmission. The blade shape of the conditioner auger (4) adopts a special involute design. This design can make the conditioner distribute more evenly during transportation, and with the gradual change of the pitch, it can effectively control the transportation speed of the conditioner, avoid blockage, which is significantly different from the common equal pitch and straight blade design in existing augers, and can better meet the requirements of conditioner spreading.

[0085] The flat key (16) is a common type A key with dimensions of 8×7×28.

[0086] The driven sprocket (10) has 40 teeth, a pitch of 15.87 mm, and a roller diameter of 10 mm.

[0087] The rotation speed sensor (14) of the auger (4) is signal-connected to the Beidou navigation system, and the automatic matching of the auger rotation speed and the tractor traveling speed is realized through the adjustment valve (12).

The lower frame (19) is fixed to components such as the corrugated disk motor support (25) and the rear ground wheel support (53) through lead screws (22)(52). This connection method of lead screws (22)(52) can accurately adjust the position and height of each component to meet different agronomic requirements. Compared with the traditional frame structure connected by simple bolts, it has higher flexibility and adaptability. It is fixed to the ditching shovel base (34) and the stirring vertical shaft (41) by bolts. One material discharging area support seat (17) is fixed on the lower support (22) by bolts.

The welding position is 150 mm away from the front end of the frame (B), and the load-bearing area of the suspension bracket is designed with triangular reinforcing ribs.

[0089] The internal of the one material discharging area support seat (17) is a hollow structure. The conditioner in the material discharging area reaches the ditching shovel (33) through the material discharging area support seat (17) and then falls into the soil.

A corrugated disk hydraulic motor (20) is installed on the side plate of the corrugated disk motor support (25). The power transmitted by the corrugated disk hydraulic motor (20) is transmitted to the corrugated disk bevel gear direction changer (23) through the corrugated disk coupling (21) to change the direction. The spline shaft (26) inside the right-angle box is matched with the spline shaft sleeve (28) on the corrugated disk (24), so that the corrugated disk (24) rotates.

[0092] The corrugated disk hydraulic motor (20) is a BMM-50 series hydraulic motor, with a flow rate of 20 L / min and a continuous output power of 1.8 KW, which is estimated to meet the requirements of the cutter head for mowing grass.

[0093] Refer to Figure 7 , the conditioner auger drive kit (33) includes a motor mounting plate (31), a 12V DC motor (30), a driving sprocket (32), a driven sprocket (10), and a motor auger (4).

[0094] The motor mounting plate (31) is located on the upper front side of the frame (B) and is an integral casting. The driving sprocket (32) is mounted on the motor shaft. Power is transmitted between the driving sprocket (32) and the driven sprocket (10) through a chain, and the driven sprocket (10) rotates to drive the auger (4) to rotate and work.

[0095] The driving sprocket (32) has 10 teeth, a pitch of 15.87 mm, and a roller diameter of 10.16 mm.

[0096] The vertical stirring shaft power drive kit (43) includes a vertical stirring shaft hydraulic motor (40), a vertical stirring shaft coupling (39), a vertical stirring shaft bevel gear reversing box (38), a spherical roller bearing with a convex base circular seat (43), a stirring shaft tube (42), and a cutter shaft flange (44).

[0097] Refer to Figure 9 , the vertical stirring shaft hydraulic motor (40) is mounted on the right side of the frame (B) and is fixed to the frame (B) by bolts. The power output from the hydraulic motor passes through the vertical stirring shaft coupling (39) and the vertical stirring shaft bevel gear reversing box (38) and turns to the stirring shaft tube (42). The power is transmitted from the stirring shaft tube (42) through the spherical roller bearing with a convex base circular seat (43) to the cutter shaft flange (44). The cutter shaft flange (44) is fixed to the vertical stirring shaft (41) by bolts, causing the vertical stirring shaft (41) to rotate and mix the soil and conditioner.

[0098] The spherical roller bearing with a convex base circular seat (43) has a good self-aligning function, ensuring the precise operation of the vertical stirring shaft (41).

[0099] The hydraulic system includes 2 regulating valves (12), 1 hydraulic oil pot (6), 1 cooling fan (5), and 2 ground wheel hydraulic telescopic rods (50).

[0100] The 2 regulating valves (12) include a corrugated disk speed regulating valve (12) and a vertical stirring shaft regulating valve (12), which are located on the support rib plate (11) on the left side of the fertilizer box. The corrugated disk speed regulating valve (12) and the vertical stirring shaft regulating valve (12) in the hydraulic system have their internal spool structures and flow control methods specially designed to accurately control the flow rate of the hydraulic oil, thereby achieving precise adjustment of the speeds of the corrugated disk (24) and the vertical stirring shaft (41).

[0101] The 1 hydraulic oil pot (6) is fixed to the support rib plate (7) on the right side of the fertilizer box by bolts. The capacity of the hydraulic oil pot (6) and the performance parameters of the hydraulic oil are also optimized according to the working requirements of this machine, ensuring the stability and reliability of the entire hydraulic system under long-term and high-intensity operations.

[0102] The air duct of the cooling fan (5) is arranged in parallel with the outlet pipe of the hydraulic oil kettle (6), and the cooling efficiency is increased by 40%.

[0103] Refer to Figure 1 、 Figure 3 For the corrugated disk speed adjustment valve (12), by changing the flow rate of the hydraulic oil flowing into the corrugated disk hydraulic motor (20) in the corrugated disk power drive kit (23), the motor speed is changed to adjust the speed of the corrugated disk (24).

[0104] For the stirring vertical shaft adjustment valve (12), by changing the flow rate of the hydraulic oil flowing into the stirring vertical shaft hydraulic motor (40) in the soil agent stirring vertical shaft power drive kit (43), the motor speed is changed to adjust the speed of the stirring vertical shaft (41).

[0105] The one hydraulic oil kettle (6) is located on the right side plate (2) of the fertilizer tank and is fixed to the right side plate (2) of the fertilizer tank by bolts. The hydraulic oil inside is regulated by the adjustment valve (12) to provide power for the corrugated disk hydraulic motor (20) and the stirring vertical shaft hydraulic motor (40).

[0106] The one cooling fan (5) is located on the right side support rib plate (7) of the fertilizer tank and is fixed to the right side support rib plate (7) of the fertilizer tank by bolts. During the operation of the hydraulic system, a large amount of heat is generated by the rotation of the hydraulic oil when it is transmitted to the hydraulic motors (23)(43) and by the movement and friction in the pipelines. Therefore, the cooling fan (5) is connected to dissipate heat during operation.

[0107] The two ground wheel hydraulic telescopic rods (50) are located on both sides of the frame (B) and are fixed to the frame (B) by pins. The telescopic stroke of the ground wheel hydraulic telescopic rods (50) is 200 mm, and they cooperate with the springs (54) to achieve self-adaptive adjustment to the ground undulation, realizing the elastic expansion and contraction of the ground wheels on uneven ground. Each hydraulic telescopic rod (50) is provided with a connection hole, which is respectively connected to the corresponding connection hole on the other side to form a closed-loop space, and the hydraulic oil forms a certain pressure inside to enable it to operate at different heights.

[0108] Refer to Figure 6 For the working components of the corrugated disk (24), they are installed on the front side of the frame (B), including the corrugated disk (24), spline shaft sleeve (28), right-angle box (27), spline shaft (26), and gasket (29). The corrugated disk (24) is assembled on the spline shaft sleeve (28), and the spline shaft (26) is nested and rotates inside the spline shaft sleeve (28) to drive the corrugated disk (24) to rotate. A gasket (29) is added at the front end of the shaft sleeve and fastened with bolts. During the operation of the machine, the corrugated disk (24) plays a role in crushing soil lumps, performing preliminary soil loosening and crushing, facilitating subsequent ditch opening and feeding operations.

[0109] Refer toFigure 8 The working component of the ditching shovel (33) is installed on the lower side of the frame (B) and directly behind the corrugated disk (24), and is fixed to the frame (B) by bolts. It consists of components such as a ditching shovel base (34), a ditching shovel tip (37), a ditching shovel curved surface (36), and a soil dividing shovel (35). The ditching shovel base (34) forms the two sides and the rear side of the working component of the ditching shovel (33). The soil dividing shovel (35) is at the upper end of the front side, the curved surface in the middle area of the front side is the ditching shovel curved surface (36), and the pointed area extending outward at the lower end is the ditching shovel tip (37). Each part is connected together by welding.

[0110] The inside of the ditching shovel base (34) is a hollow structure and is connected to the conditioner feeding area of the fertilizer box mentioned above. The conditioner is fed through the hollow area inside the ditching shovel base (34) to the soil.

[0111] The ditching shovel tip (40) first contacts the soil and cuts it, then the ditching shovel curved surface (36) transports the soil to both sides, and finally the soil dividing shovel (35) effectively levels the ground surface, eliminating the unevenness of the ground surface and creating good conditions for the subsequent mixing operation of the soil and the conditioner.

[0112] Refer to Figure 10 The working component of the stirring vertical shaft (41) is located on the lower side of the frame (B) and directly behind the ditching shovel (33). It is a combined casting and is fixed to the cutter shaft flange (44) by bolts. It consists of components such as a stirring shaft sleeve (47), a blade plate (46), a vane plate (45), and an annular plate (48).

[0113] The length of the stirring shaft sleeve (47) is 300 mm. Three annular plates (48) are evenly welded on the stirring shaft sleeve (47) from top to bottom. The diameters of the annular plates (48) gradually decrease, and the diameter of the lower plate is the smallest, which are 150 mm, 110 mm, and 80 mm respectively. Six through holes are opened on the upper plate at the end of the stirring shaft and are fixed to the cutter shaft flange (44) by bolts.

[0114] The blade plates (46) are distributed on the side of the stirring vertical shaft (41) at 120° and are welded together. Since the diameters of the annular plates (48) on the stirring shaft sleeve (47) gradually decrease, a structure of "narrow at the bottom and wide at the top" is formed when installing the blade plates (46). Such a structure is convenient for the area with severe soil surface salinization to be fully mixed with the conditioner when stirring the soil and the conditioner. At the same time, due to the large stress in the deep layer of the soil, the contact area between the bottom plate and the soil is reduced, the stirring ability is improved, and the energy consumption is reduced.

[0115] The described blade plate (45) is evenly welded onto the blade board (46). Each blade board (46) has 5 blade plates (45) with a spacing of 62 mm. The blade shape is a 90° sector shape. Tests have shown that when the stirring vertical shaft (41) rotates counterclockwise at this size, the side edges of the blade plate (45) can cut large pieces of soil into pieces so as to be fully mixed with the conditioner.

[0116] Refer to Figures 11 to 12 , the working component of the rear ground wheel (56) is located at the rear side of the frame (B) and directly behind the stirring vertical shaft (41). It consists of the rear ground wheel (56), the rear ground wheel bracket (53) and the spring (54).

[0117] The described rear ground wheel (56) is in the shape of a circular empty barrel, and there is a rear ground wheel bracket shaft (55) inside which is fixed to the empty barrel by bolts. When the machine moves forward, it drives the rear ground wheel (56) to move forward, enabling the ground wheel to complete the operation of covering soil.

[0118] One side of the described rear ground wheel bracket (53) is fixed to the frame (B) by a lead screw, and the other side is fixed to the rear ground wheel shaft by a nut.

[0119] The described spring (54) is connected to the rear ground wheel bracket (53) by a pin shaft, and the other side is suspended at the tail of the frame (B), so as to ensure that the rear ground wheel (56) can complete the operation of covering and burying soil at different heights. The working principle of the present invention:

[0120] Refer to Figure 1 , the working principle of the integrated machine for shallow loosening, ditch opening, conditioner application and rotary burying in saline-alkali land of the present invention is as follows. First, the three-point hitch at the front side of the frame is connected to the tractor, driving the machine to move forward. Secondly, the corrugated disk working component located at the front side of the machine is powered by a corrugated disk hydraulic motor, causing the corrugated disk to rotate and perform preliminary soil crushing on the soil; the conditioner in the fertilizer box is powered by a 12V DC motor hung on the frame, causing the driving sprocket to engage, and the driving sprocket and the driven sprocket drive the driven sprocket to rotate through chain drive, thereby driving the motor auger to rotate and push the conditioner into the feeding area. After the soil is cut by the ditch opener, the conditioner falls into the soil from the hollow area inside the ditch opener. The stirring vertical shaft behind the ditch opener is driven by a stirring vertical shaft hydraulic motor to drive the rotation of the shaft, thus realizing the mixing of the soil and the conditioner. Finally, the rear ground wheel at the rear side performs the operation of covering and mixing the soil.

[0121] Refer to Figure 5, the working principle of the corrugated disc working component of the present invention is as follows. First, power is provided by a hydraulic motor on the side of the motor bracket to rotate the shaft. The lateral rotation of the shaft is converted into longitudinal rotation through a coupling and a bevel gear direction-changing box. The internal shaft is engaged with a longitudinal spline shaft at the end, and the longitudinal rotation is adjusted to lateral rotation through a right-angle box to drive the lateral spline shaft to rotate. The spline shaft is engaged with a spline shaft sleeve, and the corrugated disc is installed on the spline shaft sleeve and reinforced by a gasket at the front end. The rotation of the spline shaft drives the corrugated disc to rotate and work.

[0122] Refer to Figure 7 , the working principle of the motor auger shaft of the present invention is as follows. First, power is provided by a 12V DC motor located on the upper side of the frame to drive the active sprocket to rotate. The active sprocket and the driven sprocket are driven by chain drive. The motor auger shaft is engaged with the driven sprocket, and the rotation of the driven sprocket drives the rotation of the auger shaft. The blades of the auger shaft drive the conditioner in the fertilizer box forward to the conditioner feeding area.

[0123] Refer to Figure 9 , the working principle of the vertical mixing shaft of the present invention is as follows. The vertical mixing shaft hydraulic motor located on the side of the frame transmits power to drive the rotation of the shaft. The lateral rotation of the shaft is changed into longitudinal rotation through a coupling and a bevel gear direction-changing box, causing the mixing shaft tube to rotate. The mixing shaft sleeve and the flange are fixed by bolts. Thus, the rotation of the mixing shaft tube drives the rotation of the mixing shaft sleeve. The blade plates located on the blade plate cut and mix the soil due to rotation.
