Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0039] See also Figure 1-16A corn cultivation tilling and ridging equipment of the present invention comprises: a traction beam 1, on which a plurality of tilling and ridging devices 2 and a plurality of shapers are mounted; the tilling and ridging device 2 comprises: an assembly beam 3 connected to the traction beam 1, on which a tilling wheel assembly 4, a bevel wheel assembly 5 and a ridging assembly 6 are sequentially mounted from front to back.

[0040] The working principle and technical effects of the above technical solution are as follows:

[0041] The invention discloses a corn cultivation tilling and ridging equipment, which is used for tilling and ridging soil. A traction beam 1 is provided with a plurality of bolt connection holes, which is convenient for connection with agricultural machinery such as tractors, so as to move under the drive of the agricultural machinery. A plurality of tilling and ridging devices 2 and a plurality of shapers are mounted on the traction beam 1, and the plurality of tilling and ridging devices 2 and the plurality of shapers are arranged one by one relatively. After the soil is tilled and ridged by the plurality of tilling and ridging devices 2, the ridges are shaped by the plurality of shapers. The plurality of shapers adopt the common ridge shaping equipment on the market, which can be directly purchased. The tilling and ridging device 2 in the invention is composed of a tilling wheel assembly 4, a bevel wheel assembly 5 and a ridging assembly 6. When the soil is tilled, loosened and ridged, the soil is firstly penetrated and turned by the tilling wheel assembly 4, and then the pierced soil is side-cut and stirred by the bevel wheel assembly 5, so as to effectively loosen the soil, and finally the ridging is formed by the ridging assembly 6, so that the tilling, loosening and ridging effects are good.

[0042] The tilling wheel assembly 4 includes: a supporting device 7 connected to the front part of the assembly beam 3, a tilling wheel disc 9 fixedly arranged on a movable shaft 8 rotatably arranged on the supporting device 7, a plurality of slide grooves extending from the center of the tilling wheel disc 9 to the outside are arranged around the tilling wheel disc 9, and the plurality of slide grooves are connected with slide holes arranged around the outer wheel surface of the tilling wheel disc 9; tilling assemblies 10 are slidably arranged in the plurality of slide grooves, and a plurality of tilling assemblies 10 are slidably arranged in the plurality of slide holes and can be passed out of the plurality of slide holes; and a plurality of tilling assemblies 10 are connected to an adjustment and limiting unit 11 connected to the supporting device 7.

[0043] The working principle and technical effects of the above technical solution are as follows:

[0044] The supporting device 7 is connected to the front part of the assembly beam 3, and is used for supporting the movable shaft 8 and the tilling wheel 9. When the agricultural machinery of the present invention is driven to move, the tilling wheel 9 is rotated by the friction force generated when it contacts with the soil. When the tilling wheel 9 rotates, it can drive the multiple tilling components 10 thereon to break and loosen the soil. The multiple tilling components 10 are connected to the adjustment limiting unit 11 connected to the supporting device 7. The length that the multiple tilling components 10 can pass out of the multiple slide holes can be adjusted by adjusting the limiting unit 11, thereby adjusting the soil penetration depth of the multiple tilling components 10 to meet the tillage requirements of the soil in different areas. Moreover, after tilling is completed, the multiple tilling components 10 can be adjusted by adjusting the limiting unit 11 to be retracted into the multiple slide holes, which is convenient for traction and movement on the road. There is no need to lift the entirety of the present invention, which can meet the use of various actual situations.

[0045] A driven sprocket is fixed on the movable shaft 8, and the driven sprocket is connected to the driving sprocket installed at the output end of the power motor through a chain. The power motor is assembled on the supporting device 7. In order to further improve the tillage effect and prevent the tillage wheel 9 from slipping and being unable to rotate when contacting with the soil, the power motor can be turned on. After the power motor is started, the driven sprocket is driven to rotate through the cooperation of the driving sprocket and the chain, thereby controlling the rotation of the movable shaft 8 and the tillage wheel 9, and can choose to rotate clockwise or counterclockwise according to actual conditions, so as to meet the soil breaking and loosening needs in different situations. In the direction of travel, the tillage wheel 9 is controlled to rotate clockwise, which can further improve the soil breaking effect.

[0046] The tilling assembly 10 comprises: a tilling outer tube 12 slidably arranged in the slideway hole and an outer tube slide seat 13 fixed on the tilling outer tube 12, the outer tube slide seat 13 slidably arranged in the slideway groove, and the outer tube slide seat 13 is connected to the adjustment and restriction unit 11. The adjustment and restriction unit 11 comprises: a restriction tube 14 slidably arranged on the movable shaft 8, a plurality of adjustment arms 15 are evenly connected and rotated around the restriction tube 14, the plurality of adjustment arms 15 are hingedly connected to the outer tube slide seats 13 of the plurality of tilling assemblies 10, the restriction tube 14 is rotated in the installation circular hole of the adjustment support plate 16, the adjustment support plate 16 is fixed on the adjustment horizontal shaft 17, the adjustment horizontal shaft 17 is slidably arranged in the horizontal sliding hole on the side of the support device 7, a plurality of restriction through holes are arranged side by side on the adjustment horizontal shaft 17, and the restriction through rods screwed on the support device 7 can be inserted into the restriction through holes.

[0047] The working principle and technical effects of the above technical solution are as follows:

[0048] When it is necessary to control the length of the plowing outer tube 12 extending out of the slide hole to a fixed length, first rotate the limiting rod to control the limiting rod to disengage from the limiting hole, and then control the adjusting horizontal shaft 17 to move in the horizontal sliding hole on the side of the supporting device 7 toward the plowing wheel 9. At this time, the adjusting horizontal shaft 17 drives the limiting tube 14 to approach the plowing wheel 9 through the adjusting support plate 16. The limiting tube 14 drives one end of the multiple adjusting arms 15 to move in the direction of the plowing wheel 9, and the other end of the multiple adjusting arms 15 drives multiple outer tubes of the multiple plowing assemblies 10 The slide 13 moves synchronously in multiple slide grooves in the direction away from the axis of the tilling wheel 9, thereby driving multiple tilling outer tubes 12 to extend to the outside of multiple slide holes of the tilling wheel 9 through multiple outer tube slides 13, and the extended length can be adjusted according to actual needs. After adjustment, the limiting penetration rod is controlled to be inserted into the limiting penetration hole at the corresponding position to achieve the fixation of the penetration length; and the limiting tube 14 is rotated in the mounting circular hole of the adjusting support plate 16, so that the adjusting support plate 16 and the limiting tube 14 do not interfere with each other and do not affect the rotation of the limiting tube 14.

[0049] The tilling wheel assembly 4 also includes: an assembly seat 18 fixed on the side of the adjustment horizontal axis 17 away from the adjustment support plate 16, an eccentric crankshaft 19 is slidably connected in a strip-shaped slide groove that penetrates the assembly seat 18 in the longitudinal direction, the eccentric crankshaft 19 is fixed at the eccentric position of the driven disc 20, and the driven disc 20 is rotated on the support body 21 at the side of the support device 7; the driven disc 20 is frictionally connected with the friction disc 22 fixed on the movable shaft 8. The short shaft fixed in the center hole of the driven disc 20 is slidably arranged on the support body 21, the bottom of the short shaft is rotated on the shaft bottom bracket 23, the shaft bottom bracket 23 is screwed on the screw body 24, the screw body 24 is rotated on the support body 21, and the fastening screws screwed on the support body 21 can abut against the screw body 24.

[0050] The working principle and technical effects of the above technical solution are as follows:

[0051] In order to further improve the tillage and soil-breaking effect and remove the soil adhered to the tillage outer tube 12 during tillage, the tillage outer tube 12 can also be controlled to reciprocately extend or retract into the slideway hole of the tillage wheel 9. At this time, the limiting rod is controlled to disengage from the limiting hole, and the limiting rod can be temporarily removed to prevent the limiting rod from being lost. At this time, the movable shaft 8 can drive the friction disk 22 to rotate when it rotates, and the friction disk 22 can drive the driven disk 20 to rotate by vertical friction transmission when it rotates. When the driven disk 20 rotates, it can drive the eccentric crankshaft 19 at its eccentric position to rotate and orbit. At this time, the eccentric crankshaft 19 can perform a large reciprocating sliding motion in the strip slide groove of the assembly seat 18, thereby driving the adjusting horizontal shaft 17 through the assembly seat 18 to continuously approach or move away from the tillage wheel 9 in the horizontal slide hole on the side of the supporting device 7, that is, to perform a reciprocating sliding motion. Then, by adjusting the support plate 16 and the limiting tube 14, one end of the multiple adjusting arms 15 is driven to perform reciprocating motion, and finally the multiple tilling outer tubes 12 are controlled to be reciprocatedly extended or retracted into the slideway hole of the tilling wheel 9, so as to remove the soil adhered to the tilling outer tubes 12 during tilling, and improve the subsequent tilling and breaking soil effect; in addition, if it is not necessary to drive the tilling outer tubes 12 to reciprocately extend or retract when the tilling wheel 9 rotates, the driven disc 20 can be controlled to separate from the friction disc 22. The specific operation position is: turn the fastening screw to release the lock of the screw body 24, and then turn the screw body 24 to change the contact position of the screw body 24 with the shaft bottom bracket 23, so as to drive the short shaft and the driven disc 20 to slide in the up and down directions through the shaft bottom bracket 23, and control the driven disc 20 to separate or contact with the friction disc 22 to meet the usage requirements in different situations.

[0052] The tilling assembly 10 also includes: a tilling inner tube 25, which is slidably arranged in the tilling outer tube 12, and the axial protrusion of the inner wall of the tilling outer tube 12 is slidably arranged in the axial groove of the outer wall of the tilling inner tube 25; the tilling inner tube 25 is sealed and rotatably arranged in the mounting hole of the tilling wheel 9, and the tilling inner tube 25 is passed through the liquid guide hole on the movable shaft 8, and the liquid inlet channel opened at one end of the movable shaft 8 is connected to multiple liquid guide holes, and one end of the liquid inlet pipeline 26 is rotatably connected in the liquid inlet channel, and the other end of the liquid inlet pipeline 26 is connected to the liquid supply pump.

[0053] The working principle and technical effects of the above technical solution are as follows:

[0054] In order to further improve the soil loosening effect or repair the soil, the above structure is specially designed. During tillage, the other end of the liquid inlet pipeline 26 is connected to the liquid supply pump, so that liquids such as soil loosening agents or soil repair agents are injected into the liquid inlet channel opened at one end of the movable shaft 8 through the liquid inlet pipeline 26. The liquid can enter the multiple tillage inner tubes 25 of the multiple tillage assemblies 10 through the multiple liquid guide holes on the movable shaft 8, and enter the multiple tillage outer tubes 12 through the multiple tillage inner tubes 25, and finally enter the soil through the multiple tillage outer tubes 12, so that the liquids such as soil loosening agents or soil repair agents are fully mixed with the tilled soil, rather than simply sprayed on the soil surface, which is more conducive to improving the soil loosening effect or soil repair effect.

[0055] A bevel gear 27 is fixedly mounted on each plowing inner tube 25 , and the multiple bevel gears 27 are meshed with a bevel gear ring 28 sleeved on the movable shaft 8 , and the bevel gear ring 28 is fixedly mounted on the supporting device 7 via a side bracket 30 .

[0056] When the tilling wheel 9 rotates, it can drive the bevel gears 27 of the multiple tilling inner tubes 25 to perform a circular motion. At this time, the multiple bevel gears 27 change their contact position with the bevel gear ring 28, so that the multiple bevel gears 27 rotate around their own axes, thereby driving the multiple tilling inner tubes 25 to rotate. Since the axis protrusion on the inner wall of the tilling outer tube 12 is slidably arranged in the axis groove on the outer wall of the tilling inner tube 25, when the multiple tilling inner tubes 25 rotate, the cooperation of the axis protrusion and the axis groove drives the multiple tilling outer tubes 12 to rotate, thereby further improving the effect of the tilling outer tube 12 drilling into the soil to break and loosen the soil.

[0057] A sliding tube channel 31 for the sliding of the plowing inner tube 25 and a liquid outlet channel 32 connected to the sliding tube channel 31 are provided in the plowing outer tube 12, and the diameter of the liquid outlet channel 32 is smaller than the diameter of the sliding tube channel 31; one end of the plowing inner tube 25 inserted into the sliding tube channel 31 is fixedly connected to a conical tube 33, and a cylindrical plug 34 for blocking the liquid outlet channel 32 is fixedly provided on the conical tube 33; a plurality of liquid supply holes 35 are evenly arranged around the conical tube 33.

[0058] The working principle and technical effect of the above technical scheme are as follows: in order to improve the mixing effect of liquids such as soil loosening agents or soil remediation agents and soil, and reduce the waste of liquids such as soil loosening agents or soil remediation agents, the above structure is designed to realize intermittent addition of liquids such as soil loosening agents or soil remediation agents. When multiple tilling outer tubes 12 are retracted into multiple slide holes, the tilling inner tube 25 is inserted into the slide tube channel 31 and the length becomes longer. At this time, the cylindrical plug 34 at the front end of the conical tube 33 can be sealed in the liquid outlet channel 32 to stop the output of liquid. When multiple tilling outer tubes 12 are extended to the outside of multiple slide holes, the cylindrical plug 34 is separated from the liquid outlet channel 32. At this time, the liquid in the tilling inner tube 25 can enter the slide tube channel 31 through the multiple liquid supply holes 35 on the conical tube 33, and enter the liquid outlet channel 32 for output.

[0059] The bevel wheel assembly 5 comprises: an inverted T-shaped mounting shaft 36, the upper end of which is fixed on the mounting beam 3, and the two sides of the lower end of the inverted T-shaped mounting shaft 36 are connected to two bevel wheel discs 37 inclined inwardly, and the tilling wheel assembly 4 is located between the two bevel wheel discs 37. After the soil is initially tilled by the tilling wheel assembly 4, the bevel wheel discs 37 on both sides further loosen the soil, and side bevel gears can be installed on the inner sides of the two bevel wheel discs 37, and the two side bevel gears are meshed with the main bevel gear on the rotating motor, thereby controlling the rotation of the two bevel wheel discs 37 to improve the soil breaking and loosening effect. The inclined setting of the bevel wheel discs 37 enables them to cut and loosen the soil more deeply when rotating, making the soil looser and increasing the air permeability and drainage of the soil; on the basis of the tilling wheel assembly 4, the soil is further broken, large lumps of soil in the soil are reduced, and the soil is made more uniform. Such a design reduces the need for reprocessing of the soil in subsequent operations and improves operating efficiency; the inclined setting and rotating action of the beveled wheel 37 help to mix the upper soil and the lower soil more effectively, help to evenly distribute organic matter, fertilizer and moisture in the soil, and promote crop growth.

[0060] The ridging assembly 6 includes a triangular ridging head 38, which is fixed at the lower end of an arc-shaped steel arm 39, and the upper end of the arc-shaped steel arm 39 is connected to the assembly beam 3. One end of a buffer link 40 is rotatably connected to the arc-shaped steel arm 39, and the other end of the buffer link 40 is rotated on a buffer slide 41. The buffer slide 41 is slidably fitted in the front and rear slides of the assembly beam 3, and is slidably connected to the guide transverse shaft assembled in the front and rear slides. The two ends of the buffer spring 29 mounted on the guide transverse shaft are respectively connected to the buffer slide 41 and the rear side surfaces inside the front and rear slides. The triangular ridging head 38 is used for ridging. When ridging, if there are stubborn soil lumps, it will cause a certain degree of obstruction, thereby generating backward resistance to the triangular ridging head 38 and the arc-shaped steel arm 39. At this time, the arc-shaped steel arm 39 can drive one end of the buffer link 40 to move backward, and the other end of the buffer link 40 drives the buffer slide 41 to slide in the front and rear slides of the assembly beam 3, and compresses the buffer spring 29, which plays a buffering role and reduces the hard damage to the triangular ridging head 38.
