Description

Technical Field

[0001] The invention relates to the technical field of corn rotary tillage and intercropping sowing, in particular to a corn rotary tillage and intercropping sowing machine. Background Art

[0002] During intercropping of wheat and corn in salinized farmland, soil salt migrates along the water gradient to the sides of the drip tape during drip irrigation, accumulating in the intercropping gaps. This increased moisture in these gaps causes surface salt crusts and weed growth, clogging the seed holes in the no-till corn planter and affecting seeding quality. Strip-tilling the intercropping beds is necessary to break down the salt crusts and weeds, ensuring high-quality corn seeding and improved seedbed permeability, creating an optimal seedbed environment for high-quality growth and yield. The corn rotary tillage intercropping planter features a high-clearance, cross-row design, which prevents disturbance of the wheat plants during seeding and ensures normal growth.

[0003] However, the current rotary tillage and intercropping seeders cannot effectively protect wheat straws during use. For example, the patent with publication number CN218072374U records a no-tillage seeder for wheat intercropping with corn. In the technical solution recorded in the patent, a "grass-dividing guard plate" is set to push the wheat plants outward from the middle of the two rows of wheat to prevent the machine from damaging the wheat plants during operation. The disadvantage of this method is that since the corn rotary tillage and intercropping seeder is towed forward by a tractor or other traction device, and the "grass-dividing guard plate" is fixedly installed, it will move relative to the wheat straw during the forward movement of the intercropping seeder, and the "grass-dividing guard plate" will touch and cut the wheat straw, causing damage to the wheat straw and affecting the wheat harvest. Summary of the Invention

[0004] The object of the present invention is to provide a corn rotary tillage and intercropping seeder to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A corn rotary tillage and intercropping planter comprises a rotary tiller body, on which a wheat row dividing mechanism is provided, wherein the wheat row dividing mechanism comprises two transmission shafts and two ridge dividers, wherein the two transmission shafts are driven by a driving component to rotate in opposite directions; The ridge divider includes a ridge dividing belt and at least two rollers, the rollers tighten the ridge dividing belt, and each of the two ridge dividers has a roller coaxially fixedly connected to two transmission shafts. Rotating the transmission shaft can drive the ridge dividing belt to rotate; The spacing between the two dividing ridges gradually increases in the direction from front to back, so as to push the two rows of wheat apart from the middle during the process of transporting the rows of wheat from front to back.

[0006] Preferably, the outer peripheral surface of the roller is a spherical surface, and the cross-section of the ridge dividing belt is an arc-shaped surface.

[0007] Preferably, the tops of at least two rollers are provided with a same connecting frame, the top of each connecting frame is provided with a hanger, a plurality of compensators are provided between the hanger and the connecting frame, and the hanger is fixedly connected to the driving component.

[0008] Preferably, the driving component includes a sealed shell and two meshing gears arranged inside the sealed shell. The sealed shell is installed on the rotary tiller body. A motor is installed on the top of the sealed shell. The output shaft of the motor is coaxially fixedly connected to one of the gears, and the two transmission shafts are respectively coaxially fixedly connected to the two gears.

[0009] Preferably, the transmission shaft includes a first shaft and a second shaft connected by a universal joint, the top ends of the two first shafts are respectively coaxially fixedly connected to the two gears, and each of the two ridge dividers has a roller coaxially fixedly connected to the two second shafts.

[0010] Preferably, the connecting frame includes a first connecting plate, a third shaft and a bearing, the third shaft is coaxially fixedly connected to the roller, and the first connecting plate is rotatably connected to the roller via the bearing.

[0011] Preferably, the hanger includes a second connecting plate and a reinforcing plate that are fixedly connected, and one end of the second connecting plate is fixedly connected to the sealing shell.

[0012] Preferably, the compensator includes a fourth axis, a top plate, a sliding sleeve and an elastic member; the top plate is fixedly connected to the second connecting plate; the fourth axis is hinged to the top plate through a hinge, and the abutment surface at the top of the fourth axis abuts against the lower surface of the top plate; the sliding sleeve is slidably connected to the fourth axis, and the sliding sleeve is fixed on the first connecting plate; the bottom end of the fourth axis is fixed with a bottom plate, and the elastic member is arranged between the sliding sleeve and the bottom plate.

[0013] Preferably, the outer side surface of the ridge dividing strip is provided with a plurality of convex strips.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, the ridge dividing belt of the ridge divider is set to be driven by a motor to rotate, so that the wheat straw and the ridge dividing belt can remain in a relatively static state during the contact process, thereby reducing the damage to the wheat straw during the ridge dividing process and ensuring the wheat harvest; in addition, during the operation of the intercropping seeder, the soil rolled up by the rotary tiller may stick to the ridge divider. The ridge dividing belt in this technical solution can directly prevent the wheat straw from breaking due to the adhered soil, thereby improving the ability of the wheat row ridge dividing mechanism to cope with complex environments.

[0015] 2. The present invention provides a universal joint so that the power on the first shaft can still be transmitted to the second shaft when the angle between the second shaft and the first shaft is not equal to 180°. In this way, when the squeezing force generated by the multiple wheat straws on the two ridge dividing belts on both sides of the wheat row ridge dividing mechanism (the force generated on the ridge dividing belts when the wheat straws are bent) is too large, the two ridge dividers can buffer the squeezing force by moving closer to the middle, thereby avoiding the excessive squeezing force causing the wheat straws to break or fall over, and the position of the ridge dividers can be adaptively adjusted; in addition, since the cross-section of the ridge dividing belt is an arc-shaped surface, even if the ridge divider tilts due to the two ridge dividers approaching the middle, the wheat straws can still maintain contact with the arc-shaped surface of the ridge dividing belt during the tilting of the ridge divider, thereby ensuring the stability of the wheat straw transportation process.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-10 , the present invention provides a technical solution: A corn rotary tillage and intercropping seeder includes a rotary tiller body. In this embodiment, the rotary tiller body mainly includes a frame 1, a power input shaft 2, a drip irrigation tape disc mounting frame 3, a seed box 4, a seeding disc 5, and a rotary tiller blade 6. Among them, the frame 1 serves as the framework structure of the entire machine, and the power input shaft 2, the drip irrigation tape disc mounting frame 3, the seed box 4, the seeding disc 5, and the rotary tiller blade 6 are all directly or indirectly mounted on the frame 1; the power input shaft 2 is used to connect to the power source and transmit the power to the intercropping seeder through the power input shaft 2 to drive the operation of related structures. For example, the rotary tiller blade 6 is driven by the power input by the power input shaft 2 to realize rotary tillage operation; the drip irrigation tape disc mounting frame 3 is used to install the drip irrigation tape disc to the frame 1, and a drip irrigation tape is wound around the drip irrigation tape disc. When the intercropping seeder is operating, the drip irrigation tape can be buried next to the seeds to facilitate drip irrigation operation; the seed box 4 and the seeding disc 5 can cooperate to plant corn seeds in the soil.

[0020] The above are all prior art and will not be elaborated here.

[0021] Unlike the prior art, the present invention is provided with a wheat row dividing mechanism 7 on the main body of the rotary tiller. The wheat row dividing mechanism 7 dynamically pushes the wheat rows on both sides of the rotary tiller 6 outward to prevent the rotary tiller 6 from damaging the wheat plants during operation. The details are as follows: The wheat row ridge dividing mechanism 7 includes two transmission shafts 74 and two ridge dividers 75. The two transmission shafts 74 are driven by a driving component to rotate in opposite directions. In the present technical solution, the two transmission shafts 74 rotate in opposite directions, which means that when one transmission shaft 74 rotates clockwise, the other transmission shaft 74 rotates counterclockwise. The driving component includes a sealed shell 71 and two meshing gears 73 arranged inside the sealed shell 71. The sealed shell 71 is installed on the main body of the rotary tiller. A motor 72 is installed on the top of the sealed shell 71. In the present embodiment, the motor 72 is a servo motor with an adjustable speed, so that the rotation speed of the transmission shaft 74 can be adjusted. The output shaft of the motor 72 is coaxially fixedly connected to one of the gears 73, and the two transmission shafts 74 are coaxially fixedly connected to the two gears 73 respectively. In this way, the motor 72 can be used to drive the two transmission shafts 74 to rotate in opposite directions.

[0022] In this embodiment, the ridge divider 75 includes a ridge dividing belt 752 and at least two rollers 751. For the convenience of description, the two rollers 751 are used as an example. The two rollers 751 tighten the ridge dividing belt 752 so that the whole is similar to a conveyor belt. There is a roller 751 on each of the two ridge dividers 75, which is coaxially fixedly connected to the two transmission shafts 74. Rotating the transmission shaft 74 can drive the ridge dividing belt 752 to rotate.

[0023] The spacing between the two dividing strips 752 gradually increases from front to back, so that the two rows of wheat (a row of wheat is composed of multiple wheat straws 100, or multiple wheat plants) are pushed outward from the center during the process of transporting the rows from front to back. In this technical solution, the forward direction of the telescopic planter is defined as the front direction.

[0024] To reduce the obstruction of the wheat straw 100 by the transmission shaft 74, in this embodiment, the two transmission shafts 74 are coaxially fixedly connected to the two rollers 751 located in the front. Since the distance between the front ends of the two ridge dividers 75 is less than the distance between two adjacent wheat rows, arranging the two transmission shafts 74 at the front ends of the ridge dividers 75 can prevent the transmission shafts 74 from blocking the bent wheat straw 100 and prevent the transmission shafts 74 from damaging the wheat straw 100.

[0025] Furthermore, a plurality of ridge-dividing strips 753 are provided on the outer side surface of the ridge-dividing strip 752 , which have the function of increasing the strength of the ridge-dividing strip 752 .

[0026] The working principle of the above technical solution is as follows: during the forward movement of the intercropping seeder, the rotary tiller 6 performs rotary tillage on the soil, and the corn seeds are planted in the soil through the seed box 4 and the seeding tray 5, and the drip irrigation belt is buried next to the seeds; since the two ridge dividers 75 are arranged in a manner that is narrow in front and wide in the back, the front ends of the two ridge dividers 75 may not contact the wheat straw 100 adjacent to them, and the wheat straw 100 starts to contact the ridge dividing belt 752 from the front position of the middle of the ridge divider 75; at the same time, the roller 751 rotates at a certain speed under the drive of the motor 72, thereby driving the ridge dividing belt 752 to rotate, and the conveying speed of the ridge dividing belt 752 can be adjusted to be basically consistent with the forward speed of the intercropping seeder, so that in the process of the wheat straw 100 contacting the ridge dividing belt 752 and being conveyed backward through the ridge dividing belt 752, the relative sliding between the wheat straw 100 and the ridge dividing belt 752 can be avoided as much as possible, so that the wheat straw 100 and the ridge dividing belt 752 remain in a relatively static state during the contact process. The damage to the straw 100 during the ridge dividing process can be reduced. For example, with respect to the fixed plate-like ridge dividing structure in the prior art, the straw 100 will not only directly slide over the plate-like ridge dividing structure and cause the straw 100 itself to be cut, but the friction when the straw 100 slides over the plate-like ridge dividing structure will also cause the straw 100 itself to twist, which may easily cause internal fracture of the straw 100. The present technical solution adopts a dynamic conveying method such as the ridge dividing belt 752 to avoid the above-mentioned damage to the straw 100. In addition, during the operation of the intercropping seeder, the soil rolled up by the rotary tiller 6 may adhere to the ridge divider 75. If it is a traditional fixed plate-like ridge dividing structure, the adhered soil will produce a blocking force on the straw 100 in the front and rear directions, which may easily cause the straw 100 to break. However, the ridge dividing belt 752 in the present technical solution can directly avoid the straw 100 from being broken due to the adhered soil, thereby improving the ability of the wheat row ridge dividing mechanism 7 to cope with complex environments.

[0027] The outer circumference of the roller 751 is a spherical surface 7511, and the cross-section of the ridge-dividing belt 752 is an arcuate surface. Specifically, the roller 751 is a three-dimensional structure formed by cutting off the upper and lower ends of a sphere. Its outer circumference is a spherical surface 7511, and its upper and lower ends are flat. The ridge-dividing belt 752 partially rests on the spherical surface 7511 of the roller 751, making the cross-section of the ridge-dividing belt 752 an arcuate surface. This reduces the contact area between the wheat straw 100 and the ridge-dividing belt 752.

[0028] Furthermore, the transmission shaft 74 includes a first shaft 741 and a second shaft 743 connected by a universal joint 742. The top ends of the two first shafts 741 are coaxially fixedly connected to the two gears 73 respectively. There is a roller 751 on each of the two ridge dividers 75 that is coaxially fixedly connected to the two second shafts 743 respectively. From the above description, it can be seen that the second shaft 743 is coaxially fixedly connected to the roller 751 located at the front end of the ridge divider 75. In the present technical solution, by setting the universal joint 742, the power on the first shaft 741 can still be transmitted to the second shaft 743 when the angle between the second shaft 743 and the first shaft 741 is not equal to 180°. In this way, when the squeezing force generated by the multiple wheat straws 100 on the two ridge dividing belts 752 on both sides of the wheat row ridge dividing mechanism 7 (the force generated on the ridge dividing belts 752 when the wheat straws 100 are bent) is too large, the two ridge dividers 75 can buffer the squeezing force by moving closer to the middle, thereby avoiding excessive squeezing force causing the wheat straws 100 to break or fall, and the position of the ridge divider 75 can be adaptively adjusted; in addition, since the cross-section of the ridge dividing belt 752 is an arc-shaped surface, even if the ridge divider 75 tilts due to the two ridge dividers 75 moving closer to the middle, the wheat straw 100 can still maintain contact with the arc surface of the ridge dividing belt 752 during the tilting of the ridge divider 75, thereby ensuring the stability of the straw 100 transportation process.

[0029] The top of the two rollers 751 is provided with the same connecting frame 76, and the top of each connecting frame 76 is provided with a hanger 77. Several compensators 78 are provided between the hanger 77 and the connecting frame 76. The hanger 77 is fixedly connected to the driving component. Specifically, the hanger 77 can be fixedly installed on the bottom surface of the sealing shell 71 by bolts.

[0030] Specifically, the connecting frame 76 includes a first connecting plate 761, a third shaft 762 and a bearing 763. The third shaft 762 is coaxially fixedly connected to the roller 751. The first connecting plate 761 is rotatably connected to the roller 751 through the bearing 763. The front end of the first connecting plate 761 is rotatably connected to the second shaft 743 through the bearing 763, and the rear end of the first connecting plate 761 is rotatably connected to the third shaft 762 through the bearing 763.

[0031] The hanger 77 includes a second connecting plate 771 and a reinforcing plate 772 that are fixedly connected. The second connecting plate 771 is an L-shaped plate, and the reinforcing plate 772 is a right-angled triangular plate. One end of the second connecting plate 771 is fixedly connected to the sealing shell 71.

[0032] The compensator 78 includes a fourth shaft 781, a top plate 782, a sliding sleeve 783 and an elastic member 785; the top plate 782 is fixedly connected to the second connecting plate 771; the fourth shaft 781 is hinged to the top plate 782 through a hinge 786, and the abutment surface 7811 at the top of the fourth shaft 781 abuts against the lower surface of the top plate 782; the sliding sleeve 783 is slidably connected to the fourth shaft 781, and the sliding sleeve 783 is fixed on the first connecting plate 761; the bottom end of the fourth shaft 781 is fixed with a bottom plate 784, and the elastic member 785 is arranged between the sliding sleeve 783 and the bottom plate 784.

[0033] The compensator 78 mainly works when the two ridge dividers 75 move towards the middle. Specifically, under normal conditions, the abutment surface 7811 abuts against the lower surface of the top plate 782, so that the two ridge dividers 75 cannot expand outward and can only move towards the middle of the two. Once the two ridge dividers 75 move towards the middle under the squeezing action of the wheat straw 100, the fourth axis 781 and the sliding sleeve 783 can be used to adaptively compensate for the distance change between the connecting frame 76 and the hanger 77 to ensure that the entire system can operate stably.

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
