Description

Technical Field

[0001] The present invention relates to a deep tillage and subsoiling machine, and more particularly to a deep tillage and pulverizing subsoiling machine. Background Art

[0002] Deep tillage and subsoiling is to use equipment to deeply till and pulverize the soil. After deep tillage and subsoiling, the soil layer will not be disrupted. After deep tillage and subsoiling, the nutrients, moisture and oxygen in the soil can be expanded, and the production capacity can be improved. There are mainly two types of existing deep subsoiling machines. One is to drive a deep tillage and pulverizing subsoiling head through a tractor, and the other is to drive a deep tillage and pulverizing subsoiling box through a newly developed walking machine. This machine mainly includes a walking mechanism, a frame, a cab, a power system and a deep tillage and pulverizing subsoiling device. There are two types of walking mechanisms for the above two types of subsoiling machines. One is a wheeled walking mechanism, and the other is a crawler-type walking mechanism with one crawler on each side.

[0003] For the wheeled walking mechanism, during the subsoiling process, due to the uneven ground and the cutting tools extending into the soil, the soil has a certain resistance to the cutting tools. Thus, the vibration of the entire equipment is large, which causes great damage to the equipment. In addition, the subsoiling depth of the cutting tools will change according to the bumps of the equipment, resulting in inconsistent subsoiling depths; when the wheeled deep subsoiling machine is climbing and descending slopes, the cutting tools need to be lifted relatively high so as not to interfere with the soil. In addition, when the equipment moves to the top of the slope, the front wheels will enter the downhill surface first, while the rear wheels are still on the uphill surface. If the slope is too large, the top of the slope will hit the frame, causing the equipment to be unable to move.

[0004] In the patent document with the Chinese application number 201810036210.4 and the publication date of July 3, 2018, a floating type subsoiling and ridging machine is disclosed; the subsoiling and ridging machine includes a front traction part, a floating connection device, a rear floating device, a connection device and a ridging device; the front traction part includes a front triangular crawler walking mechanism, a front frame, a power device and a cab; the floating connection device includes a front connecting frame, a rear connecting frame and a spherical plain bearing. The front connecting frame is connected to the front frame, the rear connecting frame is connected to the rear frame, and the spherical plain bearing is connected between the front connecting frame and the rear connecting frame. A buffer oil cylinder is hinged between the front frame and the rear frame; the rear floating device includes a rear triangular crawler walking mechanism, a rear frame, a hydraulic oil tank and a cooler; the connection device is hinged to the rear frame, and the ridging device is hinged to the connection device.

[0005] However, the frame of this subsoiling and ridging machine is directly fixedly connected to the front triangular crawler walking mechanism; during walking, the vibration generated by the front triangular crawler walking mechanism will be directly transmitted to the frame and then to the cab, affecting the operation of the operator; frequent vibration will cause the connections between various devices to be unstable, and at the same time will shorten the service life of the subsoiling and ridging machine; in addition, the front connecting frame and the rear connecting frame of this subsoiling and ridging machine are hinged through a conventional spherical plain bearing, and the rear floating device is not easy to reset and is prone to jamming. Summary of the Invention

[0006] The present invention provides a deep plowing, crushing and loosening machine with good shock absorption effect, which does not affect the construction of operators and is not easily jammed. By using the structure of the present invention, the deep plowing, crushing and loosening machine has better shock absorption effect, is not easily jammed, and is convenient for operators to construct.

[0007] To achieve the above object, the technical solution of the present invention is: a deep plowing, crushing and loosening machine, including a front traction device, a connecting mechanism, a rear floating fuel tank, a traveling mechanism and a deep plowing, crushing and loosening device. The front traction device is connected to the rear floating fuel tank through the connecting mechanism. The traveling mechanism is respectively hinged to both sides of the front traction device and the rear floating device. The deep plowing, crushing and loosening device is hinged to one side of the rear floating fuel tank;

[0008] The connecting mechanism includes a front connecting block, a rear connecting block, a spherical plain bearing and a hydraulic cylinder connecting mechanism. One end of the front connecting block is fixedly connected to one side of the front traction device, and the other end of the front connecting block is hinged to the spherical plain bearing. A hinge shaft passes through the spherical plain bearing. One end of the rear connecting block is hinged to the hinge shaft, and the other end of the rear connecting block is fixedly connected to the rear floating fuel tank; The hydraulic cylinder connecting mechanism is arranged between the front traction device and the rear floating fuel tank. The hydraulic cylinder connecting mechanism is two piston rod hydraulic cylinders. One end of the hydraulic cylinder is hinged to the front traction device, and the other end of the hydraulic cylinder is hinged to the rear floating fuel tank;

[0009] The traveling mechanism includes a traveling device and a traveling shock absorption device; The traveling device is respectively movably connected to the front traction device and the rear floating fuel tank. One end of the traveling shock absorption device is connected to the traveling device, and the other end of the traveling shock absorption device is respectively connected to the front traction device and the rear floating fuel tank; The traveling shock absorption device includes a traveling shock absorption fixing member one, a traveling shock absorption fixing member two, a traveling shock absorption positioning member, a traveling shock absorption adjusting member and a traveling shock absorption member;

[0010] The traveling shock absorption fixing member one is respectively connected to the front traction device and the rear floating fuel tank. The traveling shock absorption fixing member two is connected to the traveling device; The traveling shock absorption fixing member one is provided with a shock absorption adjusting hole one; The traveling shock absorption fixing member two is provided with a shock absorption adjusting hole two; The traveling shock absorption positioning member sequentially passes through the shock absorption adjusting hole two, the traveling shock absorption member and the shock absorption adjusting hole one and is connected to the traveling shock absorption adjusting member;

[0011] The rear floating fuel tank includes a bottom fuel tank and an upper fuel tank extending upward from the bottom fuel tank. An avoidance groove is provided on the side wall of the upper fuel tank. The avoidance groove penetrates through the side wall of the upper fuel tank. A fuel tank opening is provided on the fuel tank body;

[0012] The deep tillage, pulverization and soil loosening device includes a deep tillage, pulverization and soil loosening box, a hydraulic motor, a speed changer, a driven rotating gear, a rotary cutter, a rotating shaft, a heat dissipation oil tank, a heat dissipation connection assembly and a heat dissipation driving device arranged on the top of the deep tillage, pulverization and soil loosening box. An installation seat is arranged in the deep tillage, pulverization and soil loosening box, and a rotating shaft bearing is arranged on the installation seat. There are more than two rotating shafts. One end of the rotating shaft sequentially passes through the rotating shaft bearing, the driven rotating gear and the deep tillage, pulverization and soil loosening box and is hinged on the deep tillage, pulverization and soil loosening box. The driven rotating gears are meshed with each other. The other end of the rotating shaft is fixedly connected with the rotary cutter. The output end of the hydraulic motor is connected with the speed changer, and the speed changer is connected with one end of the rotating shaft far away from the rotary cutter. The heat dissipation oil tank is installed on the deep tillage, pulverization and soil loosening box, and lubricating oil is arranged in the heat dissipation oil tank. The heat dissipation driving device is connected with the rotating shaft. The heat dissipation connection assembly is respectively connected with the heat dissipation oil tank, the heat dissipation driving device and the speed changer.

[0013] The rotary cutter includes a cutter bar, a spiral blade and a soil loosening blade. The spiral blade spirally winds around the cutter bar from top to bottom and extends to the bottom of the cutter bar. More than two soil loosening blades are arranged on the spiral blade. The soil loosening blade includes a blade fixing part and a blade. The blade fixing part is installed on the spiral blade, and a blade is arranged at one end of the blade fixing part. The blade extends outward and upward in an arc shape from the blade fixing part. The arc angle of the blade installed on the spiral blade gradually increases from the bottom end to the top end of the spiral blade.

[0014] With the above settings, when the driven front frame drives the rear frame to turn through the connecting mechanism, the piston rod of one side hydraulic cylinder extends, and the piston rod of the other side hydraulic cylinder contracts. When the front frame completes the turning, the piston rods of both sides hydraulic cylinders reset under the action of hydraulic oil, so as to drive the rear connecting frame to rotate forward to the rear of the front connecting frame around the spherical plain bearing and the hinge shaft, which is convenient for resetting. When the turning angle of the front frame gradually becomes larger, the pressure in both sides hydraulic cylinders gradually becomes larger, and the turning speed of the rear connecting frame becomes faster under the action of the hydraulic oil in the hydraulic cylinder, preventing the rear connecting frame from jamming due to the too fast turning of the front connecting frame.

[0015] By connecting the walking shock absorption device with the walking device, the front traction device and the rear floating oil tank respectively, the walking shock absorption device will offset the vibration generated by the walking device; thus the vibration will not be transmitted to the front traction device and the rear floating oil tank; the shock absorption effect is good; at the same time, it does not affect the operation of the operator on the front traction device; at the same time, the walking device is shock-absorbed through the walking shock absorption device; in this way, the components on the front traction device and the rear floating oil tank will not become loose under the vibration, and further reduce the wear of the components installed on the front traction device and the rear floating oil tank; extend the service life; by setting the walking device movably connected with the front traction device and the rear floating oil tank; in this way, the walking device can move relative to the front traction device and the rear floating oil tank; when walking on rough roads; the walking device that can move relative to the front traction device and the rear floating oil tank has good passability.

[0016] The hydraulic motor installed on the top of the deep tillage, crushing and soil loosening box outputs power to the rotating shaft through a speed changer. The driven rotating gear on the rotating shaft rotates. While the rotating shaft drives the rotating cutter to rotate, the driven rotating gear on the rotating shaft drives the adjacent meshing gear to rotate, thereby driving other rotating shafts and the rotating cutters fixedly connected to the rotating shafts.

[0017] By connecting the heat dissipation driving device to the rotating shaft of the deep tillage, crushing and soil loosening box, when the rotating shaft rotates, the rotating shaft can provide power for the heat dissipation driving device; in this way, when the deep tillage, crushing and soil loosening box starts, the heat dissipation driving device will also start; the heat dissipation connection components are respectively connected to the heat dissipation oil tank, the heat dissipation driving device and the speed changer; under the action of the heat dissipation driving device, the lubricating oil enters the speed changer and then flows back into the heat dissipation oil tank; a circulation path is formed between the speed changer and the heat dissipation oil tank, so as to realize the cooling and heat dissipation of the speed changer; at the same time, it effectively avoids damage caused by dry grinding of the speed changer.

[0018] During the rotation of the rotating cutter, the soil loosening blade also rotates accordingly and crushes the soil near the cutter. Due to the arc-shaped setting of the soil loosening blade and the fact that it gradually increases from the bottom end to the top end of the spiral blade, when the cutter moves downward, due to the action of the arc, when the blade contacts the soil, the blade will not directly push the soil, but when contacting the soil, the force of the soil contacting the blade is dispersed to both ends of the blade, thereby reducing the force on the blade during movement. The load of the soil at different depths is uneven, and the force on the cutter is greater in the deeper soil. Therefore, the arc angle of the blade at the bottom end of the spiral blade is small. By reducing the arc angle of the lower blade, the force of the deep soil on the blade is changed, making the force on all blades more uniform, thereby reducing the vibration of the cutter during work. In addition, the arc angle of the upper blade increases, so the acting surface on the soil discharged upward increases, thus enabling the soil to be crushed more thoroughly and improving the crushing effect.

[0019] An upper oil tank extending upward is arranged on the bottom oil tank, effectively increasing the volume of the oil tank. The hydraulic oil pipe on the deep tillage, crushing and soil loosening machine can pass through the avoidance groove arranged on the side wall of the upper oil tank to connect other components of the deep tillage, crushing and soil loosening machine.

[0020] Further, the distance a between the hinge center lines of the two hydraulic cylinders on the side close to the front traction device is less than the distance b between the hinge center lines of the two hydraulic cylinders on the side close to the rear floating oil tank, and the stroke of the hydraulic cylinder is c; the ratio of a:b:c is 65 - 75:25 - 35:34. With the above ratio relationship of a:b:c and the two hydraulic cylinders designed in a V shape, when driving the rear frame to swing, it is not easy to get stuck, and the stiffness of the piston rod of the hydraulic cylinder can also be guaranteed to a certain extent; due to the V-shaped design of the two hydraulic cylinders, when one of the hydraulic cylinders extends, a force backward and outward is generated on the rear frame, and the traveling mechanism of the rear frame is located behind the connecting mechanism, so it is easier for the rear frame to swing.

[0021] Further, fixing plates are respectively provided at both ends of the spherical plain bearing, and the fixing plates are respectively fixedly connected to the spherical plain bearing and the rear connecting block, thus preventing the spherical plain bearing from falling off.

[0022] Further, the traveling device includes a traveling crawler frame and a traveling drive assembly; the traveling drive assembly is installed on the traveling crawler frame; the traveling crawler frame is respectively movably connected to the front traction device and the rear floating oil tank; the second traveling shock absorber fixing member is connected to the traveling crawler frame. With the above settings, since the traveling drive assembly is installed on the traveling crawler frame; it is movably connected to the frame through the traveling crawler frame and connected through the traveling crawler frame traveling shock absorber device; this does not affect the operation of the traveling drive assembly.

[0023] Further, the traveling drive assembly includes a first traveling idler, a second traveling idler, a traveling drive wheel, a traveling drive device, a traveling crawler and a traveling swing assembly; the first traveling idler is installed at one end of the traveling crawler frame, the second traveling idler is installed at the other end of the traveling crawler frame, and the traveling drive wheel is installed on the traveling crawler frame; the traveling swing assembly is hinged to the bottom of the traveling crawler frame; both the traveling drive wheel and the traveling swing assembly are located between the first traveling idler and the second traveling idler; the traveling drive device is connected to the traveling drive wheel; a traveling crawler is sleeved on the first traveling idler, the second traveling idler, the traveling swing assembly and the traveling drive wheel;

[0024] The traveling drive assembly further includes load wheels; the traveling swing assembly includes more than one traveling swing frame, and the traveling swing frame is hinged to the bottom of the traveling crawler frame, and load wheels are respectively installed at both ends of the traveling swing frame; the traveling crawler is sleeved on the first traveling idler, the second traveling idler, the load wheels and the traveling drive wheel. With the above settings, by providing the hinged traveling swing assembly, when the traveling device travels, the contact effect between the traveling crawler and the traveling swing assembly is good; the traveling swing frame will change according to the movement of the traveling crawler, so that the traveling crawler can contact at least one load wheel on one traveling swing frame, making the traveling more reliable and stable.

[0025] Furthermore, it further includes a walking connection device; the walking crawler frame is provided with a walking connection through-hole; the walking connection device includes a walking connection fixing member and a walking connection member; one end of the walking connection member is respectively hinged to the front traction device and the rear floating fuel tank; the other end of the walking connection member passes through the walking connection through-hole and is connected to the walking connection fixing member, and the walking connection fixing member fixes the walking connection member on the walking crawler frame.

[0026] Furthermore, the load-bearing wheel includes a load-bearing wheel body; characterized in that: the load-bearing wheel body includes a track roller, a track roller end cover, a track roller shaft, a floating seal seat, a floating seal structure, a tapered roller bearing, a connecting backing plate and a nut.

[0027] The track roller shaft is arranged inside the track roller, a limiting groove is arranged inside the track roller, the inner ring of the tapered roller bearing is connected to the track roller shaft, the outer ring of the tapered roller bearing is connected to the limiting groove of the track roller, the track roller end covers are fixedly installed at both ends of the track roller, the floating seal seat is arranged on the track roller shaft and sleeved with the track roller end cover, and the floating seal mechanism is arranged at both ends of the track roller shaft and on one side of the track roller end cover and the floating seal seat.

[0028] The floating seal mechanism includes a floating seal ring and a rubber ring. The floating ring is sleeved at one end of the track roller shaft. A conical surface is arranged in the middle of the outer surface of the floating ring, and a floating protrusion is arranged in the middle of the conical surface. The rubber ring is arranged on the conical surfaces on both sides of the floating protrusion. The inclined surface of the track roller end cover presses on one of the rubber rings of the floating seal mechanism, and the inclined surface of the floating seal seat presses on the other rubber ring of the floating seal mechanism. With the above settings, the floating seal seat is sleeved on the track roller end cover, and together with the floating seal mechanism, even if the track roller shaft is bent and deformed, since the track roller end cover and the floating ring press the rubber ring, and the floating seal seat and the floating ring press the rubber ring, therefore, through the rubber ring, dust and dirt are not easily allowed to enter the inside of the track roller. The floating seal mechanism is arranged on one side of the track roller end cover and the floating seal seat. Even if dirt enters the inside of the track roller, the dirt entering from between the floating seal seat and the track roller end cover is blocked by the rubber ring arranged on the floating seal ring, playing a role of sealing and protecting the track roller and the track roller shaft. By arranging a tapered roller bearing between the track rollers through the track roller shaft, the friction between the track roller and the track roller shaft is reduced. At the same time, the tapered roller bearing is in rolling connection with the limiting groove inside the track roller, playing a role of limiting the track roller. In this way, the load-bearing wheel structure has good sealing effect and small friction.

[0029] Furthermore, the track roller includes a first track roller and a second track roller.

[0059] The present invention will be further described in detail below with reference to the drawings and specific implementation modes.

[0060] Embodiment 1

[0061] As Figures 1 - 24 shown, a deep plowing, crushing and soil loosening machine includes a front traction device 1j, a connecting mechanism 3j, a rear floating fuel tank 2j, a traveling mechanism 10j and a deep plowing, crushing and soil loosening device 4j. The front traction device 1j is connected to the rear floating fuel tank 2j through the connecting mechanism 3j. The traveling mechanism is respectively hinged to both sides of the front traction device 1j and the rear floating fuel tank 2j. The deep plowing, crushing and soil loosening device 4j is hinged to one side of the rear floating fuel tank 2j; a cockpit 100j is also provided on the front traction device 1j.

[0062] The connecting mechanism 3j includes a front connecting block 31j, a rear connecting block 32j, a spherical plain bearing 33j and a hydraulic cylinder connecting mechanism. One end of the front connecting block 31j is fixedly connected to one side of the front traction device 1j. The other end of the front connecting block 31j is hinged to the spherical plain bearing. A hinge shaft 33j passes through the spherical plain bearing. One end of the rear connecting block 32j is hinged to the hinge shaft 33j. The other end of the rear connecting block 32j is fixedly connected to the rear floating fuel tank 2j; the hydraulic cylinder connecting mechanism 3j is arranged between the traveling mechanism 10j of the front traction device 1j and the rear floating fuel tank 2j. The hydraulic cylinder connecting mechanism 3j is two piston rod hydraulic cylinders 34j. One end of the hydraulic cylinder 34j is hinged to the front traction device 1j.

When the front traction device completes the turning, the piston rods of both sides hydraulic cylinders reset under the action of hydraulic oil, thereby driving the rear connecting frame to rotate forward and directly behind the front connecting frame around the spherical plain bearing and the hinge shaft, which is convenient for resetting; when the turning angle of the front traction device gradually becomes larger, the pressure in both sides hydraulic cylinders gradually becomes larger. By adopting the above ratio relationship of a: b: c and the two hydraulic cylinders adopt an eight-shaped design, in this way, it is not easy to get stuck when driving the rear frame to swing, and the rigidity of the piston rod of the hydraulic cylinder can also be guaranteed to a certain extent; due to the eight-shaped design of the two hydraulic cylinders, when one of the hydraulic cylinders extends, it generates a backward and outward force on the rear frame, and the traveling mechanism of the rear frame is located behind the connecting mechanism, so it is easier for the rear frame to swing.

[0064] Fixed plates 331j are respectively provided at both ends of the spherical plain bearing 33j, and the fixed plates 331j are respectively fixedly connected to the spherical plain bearing 33j and the rear connecting block 32j, so as to prevent the spherical plain bearing from falling off. The cylinder body of the hydraulic cylinder 34j is hinged on the front traction device 1j, and the piston rod of the hydraulic cylinder 34j is hinged on one side of the rear floating fuel tank 2j.

[0065] The traveling mechanism includes a traveling device 1n and a traveling shock-absorbing device 2n; the traveling device 1n is movably connected to the frame 3n, one end of the traveling shock-absorbing device 2n is connected to the traveling device 1n, and the other end of the traveling shock-absorbing device 2n is connected to the frame 3n.

[0066] As Figures 2 - 4 shown; the traveling device 1n includes a traveling crawler frame 11n, a traveling drive assembly 12n, and a traveling connection device 13n; the traveling drive assembly 12n is installed on the traveling crawler frame 11n.

[0068] The walking shock absorption device 2n includes a first walking shock absorption fixing member 21n, a second walking shock absorption fixing member 22n, a walking shock absorption positioning member 23n, a walking shock absorption adjusting member 24n, and a walking shock absorption member 25n. The first walking shock absorption fixing member 21n is connected to the frame 3n, and the second walking shock absorption fixing member 22n is connected to the walking track frame 11n; the first walking shock absorption fixing member 21n is provided with a first shock absorption adjustment hole 211n; the second walking shock absorption fixing member 22n is provided with a second shock absorption adjustment hole 222n. In this embodiment, the walking shock absorption positioning member is a bolt, the walking shock absorption adjusting member is a nut, and the walking shock absorption member 2 is a spring. The walking shock absorption positioning member 23n sequentially passes through the second shock absorption adjustment hole 222n, the walking shock absorption member 25n, and the first shock absorption adjustment hole 211n and is connected to the walking shock absorption adjusting member 24n. By rotating the walking shock absorption adjusting member, the position of the walking shock absorption adjusting member on the walking shock absorption positioning member is changed, so as to change the length between the first walking shock absorption fixing member and the second walking shock absorption fixing member. When the length between the first walking shock absorption fixing member and the second walking shock absorption fixing member shrinks, the walking shock absorption member is in a compressed state; when the length between the first walking shock absorption fixing member and the second walking shock absorption fixing member returns to the initial state, the walking shock absorption member is in an extended state, so that the walking shock absorption device can be adjusted.

[0069] Because the walking drive assembly is installed on the walking track frame 11n; the walking track frame 11n is movably connected to the frame 3n, and the walking shock absorption device 2n is connected through the walking track frame 11n; this does not affect the operation of the walking drive assembly.

In this way, the traveling swing frame 126n will change according to the movement of the traveling track 125n, so that the traveling track 125n can contact at least one load wheel 123n on one traveling swing frame 126n, making the traveling more reliable and stable.

[0072] The traveling device 1n and the frame 3n are connected through the traveling shock-absorbing device 2n, and the traveling shock-absorbing device 2n will offset the vibration generated by the traveling device 1n; thus, the vibration will not be transmitted to the frame 3n; the shock-absorbing effect is good; at the same time, it does not affect the construction of the operators on the frame 3n; at the same time, the traveling device 1n is shock-absorbed through the traveling shock-absorbing device 2n; in this way, the components on the frame 3n will not become loose under vibration, thereby reducing the wear of the components installed on the frame 3n; extending the service life; by setting the traveling device 1n that is movably connected to the frame 3n; in this way, the traveling device 1n can move relative to the frame 3n; when traveling on rough roads; the traveling device 1n that moves relative to the frame 3n has good passability.

[0073] The load wheel 123n includes a load wheel body 1f and connection ears 2f for connecting both sides of the load wheel body. The load wheel body includes a support roller 11f, a support roller end cover 12f, a support roller shaft 13f, a floating seal seat 14f, a floating seal structure 15f, a tapered roller bearing 16f, a connection backing plate 17f and a nut 18f.

The inner ring of the tapered roller bearing 16f is connected to the support roller shaft 13f, and the outer ring of the tapered roller bearing 16f is connected to the limiting groove 110f of the support roller 11f. The support roller end cover 12f is fixedly installed at both ends of the support roller 11f. The floating seal seat 14f is arranged on the support roller shaft 13f and is sleeved with the support roller end cover 12f. The floating seal mechanism 15f is arranged at both ends of the support roller shaft 13f and is located on one side of the support roller end cover 12f and the floating seal seat 14f.

[0075] The structure of the floating seal mechanism 15f includes a floating seal ring 151f and a rubber ring 152f. The floating ring 151f is sleeved on one end of the carrier wheel shaft 13f. A conical surface 1511f is provided in the middle of the outer surface of the floating ring 151f, and a floating protrusion 1512f is provided in the middle of the conical surface 1511f.

Both ends of the carrier wheel shaft 13f pass through the hole positions of the connecting backing plate 17f and are threadedly connected to the nuts 18f.

[0077] Because the floating seal seat is sleeved on the carrier wheel end cover, and together with the floating seal mechanism, even if the carrier wheel shaft 13f is bent and deformed, due to the carrier wheel end cover and the floating ring pressing the rubber ring, and the floating seal seat and the floating ring pressing the rubber ring, therefore, dust and dirt are not easily allowed to enter the inside of the carrier wheel through the rubber ring. The floating seal mechanism is arranged on one side of the carrier wheel end cover and the floating seal seat. Even if dirt enters the inside of the carrier wheel, the dirt entering from between the floating seal seat and the carrier wheel end cover is blocked by the rubber ring arranged on the floating seal ring, playing a role of sealing and protecting the carrier wheel and the carrier wheel shaft. By arranging tapered roller bearings between the carrier wheels on the carrier wheel shaft, the friction between the carrier wheel and the carrier wheel shaft is reduced. At the same time, the tapered roller bearings are in rolling connection with the limiting grooves inside the carrier wheels, playing a role of limiting the carrier wheels. In this way, the load-bearing wheel structure has a good sealing effect and small friction.

[0078] The carrier wheel 11f includes a first carrier wheel 111f and a second carrier wheel 112f. The first carrier wheel 111f is provided with a guiding protrusion 1111f, and the second carrier wheel 112f is provided with a guiding groove 1121f.

With the above settings, it is convenient to install the tapered roller bearings and the floating seal mechanism inside the carrier wheel. After installation, the first carrier wheel and the second carrier wheel can be inserted through the guiding protrusion and the guiding groove, and the installation is convenient.

[0079] A welding groove 1101f is provided on one side of the guiding protrusion 1111f, and a welding groove 1101f is provided on one side of the guiding groove 1121f. In this way, the first carrier wheel and the second carrier wheel can be welded through the welding grooves after being inserted.

[0082] Elastic pins 19f are respectively arranged at both ends of the idler shaft 13f. The idler shaft 13f is fixedly connected to the floating seal seat 14f through the elastic pins 19f. The elastic pins 19f have good elasticity and shear resistance, and the floating seal seat 14f is stably installed.

[0083] The inner side of the floating seal seat 14f is provided with a second sealing ring 141f to enhance the sealing performance of the floating seal seat 14f.

[0084] The deep tillage, crushing and soil loosening device 4j includes a deep tillage, crushing and soil loosening box 3b, a hydraulic motor 2h arranged at the top of the deep tillage, crushing and soil loosening box 3b, a speed changer, a driven rotating gear 34b, a rotary cutter 5h, a rotating shaft 33b, a heat dissipation oil tank 1b, a heat dissipation connection assembly, a heat dissipation driving device and a cooling device 2b.

[0085] In this embodiment, there are two speed changers, namely a first speed changer 31b and a second speed changer 32b. In this embodiment, there is one heat dissipation driving device, and the heat dissipation driving device is a first heat dissipation driving device 41b. The height of the volume space of the heat dissipation oil tank 1b is the same as the height of the volume spaces of the first speed changer 31b and the second speed changer 32b.

[0086] The first speed changer 31b, the second speed changer 32b and the first heat dissipation driving device 41b are all installed on the adjacent rotating shaft 33b. A driven rotating gear 34b is arranged on the rotating shaft 33b. The adjacent driven rotating gears 34b are meshed with each other.

[0087] In this embodiment, there are two cooling devices 2b, and the cooling device 2b is a lubricating oil cooler; the cooling device is a prior art and will not be described in detail here. The heat dissipation oil tank 1b is provided with two heat dissipation oil inlets one (not shown in the figure) and one heat dissipation oil outlet one (not shown in the figure); the first heat dissipation driving device 41b is provided with one heat dissipation oil inlet two (not shown in the figure) and two heat dissipation oil outlets two (not shown in the figure); both the first speed changer 31b and the second speed changer 32b are provided with one heat dissipation oil inlet three (not shown in the figure) and one heat dissipation oil outlet three (not shown in the figure); in this embodiment, the heat dissipation oil outlet three is arranged at the bottom of the first speed changer 31b and the second speed changer 32b.

[0088] The cooling device 2b is provided with one heat dissipation oil inlet four (not shown in the figure) and one heat dissipation oil outlet pipeline (not shown in the figure). The heat dissipation connection assembly includes a heat dissipation pipeline one 51b, a heat dissipation pipeline two 52b, and a heat dissipation pipeline three 53b. In this embodiment, there is one heat dissipation pipeline one 51b; there are two heat dissipation pipelines two 52b; there are two heat dissipation pipelines three 53b.

[0089] The heat dissipation pipeline one 51b connects the heat dissipation oil outlet one and the heat dissipation oil inlet two; one of the heat dissipation pipelines two 52b connects one of the heat dissipation oil outlets two and the heat dissipation oil inlet three of the first speed changer 31b; the other heat dissipation pipeline two 52b connects the other heat dissipation oil outlet two and the heat dissipation oil inlet three of the second speed changer. One of the heat dissipation pipelines three 53b connects the heat dissipation oil outlet three of the first speed changer 31b and the heat dissipation oil inlet four of one of the cooling devices 2b; the other heat dissipation pipeline three 53b connects the heat dissipation oil outlet three of the second speed changer 32b and the heat dissipation oil inlet four of the other cooling device 2b. The two heat dissipation oil outlet pipelines are connected to the two heat dissipation oil inlets one.

[0090] In this embodiment, the liquid level display member 11b is a liquid level gauge; the heat dissipation driving device is an oil pump. Using a liquid level gauge is convenient for viewing, and the heat dissipation driving device being an oil pump can pump out the lubricating oil in the heat dissipation oil tank.

[0091] By setting up the cooling device 2b, since the lubricating oil will absorb the heat generated by the speed changer when it enters the interior of the speed changer; by setting up the cooling device 2b to cool the lubricating oil; the cooled lubricating oil flows back into the heat dissipation oil tank 1b; the temperature of the lubricating oil in the heat dissipation oil tank 1b is not likely to rise; thus, the heat dissipation effect on the speed changer is good. By connecting the heat dissipation driving device to the rotating shaft 33b of the deep plowing, crushing and soil loosening box 3b, when the rotating shaft 33b rotates, the rotating shaft 33b can provide power for the heat dissipation driving device; in this way, when the deep plowing, crushing and soil loosening box 3b starts, the heat dissipation driving device will also start; connect the heat dissipation oil tank 1b and the heat dissipation driving device through the first heat dissipation pipeline 51b; connect the heat dissipation driving device and the speed changer through the second heat dissipation pipeline 52b; connect the speed changer and the heat dissipation oil tank 1b through the third heat dissipation pipeline 53b; under the action of the heat dissipation driving device, the lubricating oil enters the speed changer and then flows back into the heat dissipation oil tank 1b; a circulation path is formed between the speed changer and the heat dissipation oil tank, so as to achieve the cooling and heat dissipation of the speed changer; at the same time, it effectively avoids the damage caused by dry grinding of the speed changer; at the same time, because the heat dissipation oil tank 1b is connected to the speed changer; at the same time, because the volume spaces of the speed changer and the heat dissipation oil tank are of the same height; thus, the horizontal position of the lubricating oil in the heat dissipation oil tank is consistent with the horizontal position of the lubricating oil in the speed changer; by setting a liquid level display part on the heat dissipation oil tank, the oil amounts of the lubricating oil in the heat dissipation oil tank and the speed changer can be observed, which is convenient for monitoring the use condition of the lubricating oil.

[0092] The rotary cutter 5h includes a cutter bar 1y, a spiral blade 2y and a soil loosening blade 3y.

[0093] The spiral blade 2y spirally winds around the cutter bar 1y from top to bottom and extends to the bottom of the cutter bar 1y, and more than two soil loosening blades 3y are arranged on the spiral blade 2y; the soil loosening blade 3y includes a blade fixing part 31y and a blade 32y, the blade fixing part 31y is installed on the spiral blade 2y, and a blade 32y is arranged at one end of the blade fixing part 31y, and the blade 32y extends outward and upward in an arc shape from the blade fixing part 31y; the arc angle of the blade 32y installed on the spiral blade 2y gradually increases from the bottom end to the top end of the spiral blade 2y.

[0094] An earth-entering blade 21y is arranged at the end of the spiral blade 2y, and the earth-entering blade 21y extends downward and obliquely from the end of the spiral blade 2y. By setting the earth-entering blade, when the cutter needs to drill deep into the cultivated land, the soil can be better excavated and the earth-entering can be assisted.

[0095] The blade 32y has a front portion 321y, a rear portion 322y, and an end portion 323y. A chip cutting edge 3211y is provided on the front portion 321y; the chip cutting edge 3211y is formed by obliquely extending forward and downward from the middle of the blade 32y to the front portion 321y. An end chip cutting edge 3231y is formed by extending from the bottom surface to the top surface and outward at the end portion 323y, and the end chip cutting edge 3231y is higher than the chip cutting edge 3211y; the end portion 323y obliquely extends from the front portion 321y toward the blade fixing portion 31y in the direction of the rear portion; with the above settings, due to the provision of the chip cutting edge and the end chip cutting edge, after the deep tillage, crushing and loosening machine blade is installed on the spiral blade of the tool and the tool rotates, the chip cutting edge chips and loosens the soil in the front portion, and the end chip cutting edge chips and loosens the soil on the side of the tool. Since the chip cutting edge and the end chip cutting edge are arranged in a vertically offset manner, the acting forces of the soil on the chip cutting edge and the end chip cutting edge will also be offset in the vertical direction, so that the chip cutting force is dispersed and not concentrated. In addition, since the blade is arc-shaped, the chip cutting edge is also arc-shaped. In this way, in the vertical direction, the acting forces on the chip cutting edge are not on the same horizontal plane, and the chip cutting force is also dispersed. Therefore, the strength requirement for the deep tillage, crushing and loosening machine blade is reduced, and the service life of the deep tillage, crushing and loosening machine blade is increased. Since the end portion obliquely extends from the front portion toward the blade fixing portion in the direction of the rear portion and an end chip cutting edge is formed at the end portion, in this way, at the end of the blade, as the blade rotates with the tool, the resistance of the blade to the soil in the front portion is reduced.

[0096] The chip cutting edge 3211y protrudes from the front portion of the blade fixing portion 31y. In this way, it is easier for the blade to cut into the soil.

[0097] The width of the blade 32y gradually increases from one end of the blade fixing portion 31y to the end away from the blade fixing portion 31y. This enables the blade to play a certain role of the spiral blade and increases the effect of discharging soil upward.

[0098] An installation hole 310y is provided on the blade fixing portion 31y. In this way, it is convenient to fix the deep tillage, crushing and loosening machine blade

[0099] The chip cutting edge 3211y and the front portion of the blade fixing portion 31y have a circular arc transition. With this structure, when the chip cutting edge cuts the soil, it can guide the flow direction of the soil, that is, make part of the soil on the blade flow toward the direction of the blade fixing portion and guide part of the soil to the spiral blade where the deep tillage, crushing and loosening machine blade is installed, improving the efficiency of discharging soil upward and thus improving the soil loosening effect.

[0100] The blade fixing part 31y is located below the spiral blade 2y. More than two connecting bolts 33y arranged along the length direction of the subsoiling blade 3y are connected between the blade fixing part 31y and the spiral blade 2y. A blade limiting part 34y is arranged on one side of the spiral blade 2y where the blade fixing part 31y is located. The blade limiting part 34y resists the blade fixing part 31y and is arranged close to the outer connecting bolt 33y. With the above settings, when the tool rotates, the blade chips the soil, generating a chipping force on the blade. The chipping force is transmitted to the blade fixing part, which then transmits the force to the connecting bolts and the blade limiting part. Through the resistance of the blade limiting part, the shearing force of the blade fixing part on the connecting bolts is greatly reduced, effectively reducing the failure of the tool caused by the fracture of the connecting bolts and improving the service life of the tool. In addition, only a blade limiting part for resisting the blade fixing part is arranged on the back of the blade fixing part. Based on the spiral blade spirally wound from the lower end to the upper end of the guide rod, the upper spiral blade is higher than the lower spiral blade. In this way, the bottom of the blade limiting part will be higher than or flush with the front part of the blade fixing part, without bringing greater resistance to the tool for chipping the soil.

Using a liquid level gauge is convenient for viewing, and the heat dissipation driving device being an oil pump can realize pumping out the lubricating oil in the heat dissipation oil tank.

[0119] By setting up the cooling device 2b, since the lubricating oil will absorb the heat generated by the speed changer when it enters the interior of the speed changer; by setting up the cooling device 2b to cool the lubricating oil; the cooled lubricating oil flows back into the heat dissipation oil tank 1b; the temperature of the lubricating oil in the heat dissipation oil tank 1b is not likely to rise; thus, the heat dissipation effect on the speed changer is good. By connecting the heat dissipation driving device to the rotating shaft of the deep tillage, crushing and soil loosening box, when the rotating shaft rotates, the rotating shaft can provide power for the heat dissipation driving device; in this way, when the deep tillage, crushing and soil loosening box starts, the heat dissipation driving device will also start; connect the heat dissipation oil tank 1b and the heat dissipation driving device through the first heat dissipation pipeline 51b; connect the heat dissipation driving device and the speed changer through the second heat dissipation pipeline 52b; connect the first speed changer 31b and the second speed changer 32b through the heat dissipation pipeline 54b; connect the second speed changer 32b and the heat dissipation oil tank 1b through the third heat dissipation pipeline 53b; under the action of the heat dissipation driving device, the lubricating oil enters the speed changer and then flows back into the heat dissipation oil tank 1b; a circulation path is formed between the speed changer and the heat dissipation oil tank, thus realizing the cooling and heat dissipation of the speed changer; at the same time, effectively avoiding damage caused by dry grinding of the speed changer; at the same time, because the heat dissipation oil tank 1b is connected to the speed changer; at the same time, because the volume space heights of the speed changer and the heat dissipation oil tank are the same; in this way, the horizontal positions of the lubricating oil in the heat dissipation oil tank and the lubricating oil in the speed changer are kept consistent; by setting a liquid level display component on the heat dissipation oil tank, the oil amounts of the lubricating oil in the heat dissipation oil tank and the speed changer can be observed, which is convenient for monitoring the use situation of the lubricating oil.
