Description

Technical Field

[0001] This application relates to the field of crop breeding experiment technology, and in particular to a sowing and furrowing roller device for crop breeding. Background Technology

[0002] In the breeding process of crops (such as wheat, corn, peanuts, soybeans, etc.), precise manual sowing is required. Conventional devices use a rotating roller on the ground to press furrows with equidistant triangular iron bars on the roller. Each triangular iron bar has cylindrical nails spaced 10 cm apart and 2 cm high to fix the distance of seed sowing. After the roller has been leveled by a rotary tiller, it immediately begins to press furrows. Regarding the cylindrical nails in the conventional structure, the inventor discovered the following defects:

[0003] 1. The cylindrical nails on the surface of the roller are welded and fixed, and the protrusion height is not adjustable. They can only form a single depth of planting hole. Different crops such as wheat, corn, and soybeans require different planting hole depths, and the entire set of rollers needs to be replaced for different planting hole depths of different crops, resulting in poor versatility.

[0004] 2. All cylindrical nails rise and fall synchronously, and cannot be used intermittently or partially retracted. During multi-density comparison experiments in breeding, it is not possible to flexibly switch between single-row or inter-row fixed-point planting holes.

[0005] Therefore, in response to the above problems, the applicant provides a sowing and furrowing roller device for crop breeding. Summary of the Invention

[0006] In order to solve the problems mentioned in the background art, this application provides a sowing and furrowing roller device for crop breeding.

[0007] This application provides a sowing and furrowing roller device for crop breeding, which adopts the following technical solution:

[0008] A sowing and furrowing roller device for crop breeding includes a roller and multiple sets of adjusting components on the roller for adjusting the different positions of cylindrical nails. Each adjusting component includes a disc with a first limiting groove on the disc that allows the cylindrical nails to move up and down at an adjustable height. A positioning wheel is slidably connected in the first limiting groove, and the two ends of the positioning wheel are rotatably disposed in corresponding fixing holes on both sides of the cylindrical nail.

[0009] Each set of adjustment components is independently installed on the roller, and the independently installed height adjustment components can protrude at intervals or all of them to use the height adjustment components.

[0010] Optionally, each set of adjustment components consists of multiple disks, each of which has a first limiting groove extending from the outer circumference of the disk to the center of the disk.

[0011] Optionally, a groove is provided from the middle to the bottom of the cylindrical nail, scale values ​​are engraved on the outer circumference of the cylindrical nail, and the top of the cylindrical nail is set as an arc surface.

[0012] Optionally, a connecting rod is fixedly connected to the center of each of the multiple discs. A throttle is fixedly connected to one end of the connecting rod, and one end of the cylindrical nail passes through a fixed sleeve. A disc screw is threaded onto the fixed sleeve, and one end of the disc screw is rotatably connected to a locking block. The disc screw and the locking block constitute a positioning element. The bottom surface of the locking block presses against the protrusion on the connecting rod, and the locking block is limited to the second limiting groove opened in the fixed sleeve.

[0013] Optionally, the roller has through holes arranged in a ring array to facilitate the insertion of connecting rods, and the roller also has placement slots extending from the through holes for placing discs, the placement slots being connected to the limiting holes of limiting cylindrical nails.

[0014] Optionally, it also includes a roller, wherein multiple triangular iron pillars of strip-shaped structure are welded to the outer circumference of the roller, and the cylindrical nails can also be welded equidistantly around the outer circumference of the roller, and the roller is also mounted on a rotary tiller.

[0015] Optionally, the distance between two adjacent sets of height adjustment components is 10cm, and the maximum protrusion height of the cylindrical nail is between 2cm and 5cm.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. The present invention uses the rotation of the disc to make the height of the first limiting groove adjustable by the positioning wheel and the cylindrical nail. By flexibly adjusting the height of the cylindrical nail, it can be adapted to the planting depth of different crops, and there is no need to replace the cylindrical nails and rollers of different heights for crops with different planting depths, thereby greatly increasing its versatility.

[0018] 2. By setting the adjustment components as independent and non-interlocking structures, the cylindrical nails on the roller can be lowered as a whole or protruded at intervals, thus avoiding the limitation of conventional cylindrical nail fixing, which can only achieve one state and is not convenient for flexibly switching between single row or intermittent row fixed-point planting holes.

[0028] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0029] This application discloses a sowing and furrowing roller device for crop breeding.

[0030] like Figure 1-8 As shown, a sowing and furrowing roller device for crop breeding includes a roller 1 and multiple sets of adjustment components on the roller 1 for adjusting the different positions of cylindrical nails 23. The adjustment components include a disc 21, on which a first limiting groove 210 is provided to drive the cylindrical nails 23 to adjust their height. A positioning wheel 22 is slidably connected in the first limiting groove 210. The two ends of the positioning wheel 22 are rotatably disposed in the corresponding fixing holes 231 on both sides of the cylindrical nails 23.

[0031] Among them, the rotating connecting rod 20 can drive the disc 21 to rotate synchronously, the first limiting groove 210 pushes the positioning wheel 22 to move radially, and drives the cylindrical nail 23 to rise and fall vertically along the limiting hole 14.

[0032] Each set of adjustment components is independently installed on the roller 1. The independently installed height adjustment components can protrude at intervals or all of them to use the height adjustment components.

[0033] Each adjustment component is independently controlled, allowing the cylindrical nails 23 to be lowered individually or retracted completely.

[0034] Please see Figure 1 and Figure 3 Each set of adjustment components consists of multiple discs 21, and each of the multiple discs 21 has a first limiting groove 210 extending from the outer circumference of the disc 21 to the center of the disc 21.

[0035] Please see Figure 1 The cylindrical nail 23 has a groove 230 from the middle to the bottom, and the outer circumference of the cylindrical nail 23 is engraved with scale values ​​232. The top of the cylindrical nail 23 is set as an arc surface 233.

[0036] When the cylindrical nail 23 is fully retracted and the arc surface 233 is flush with the outer wall of the roller 1, the groove 230 engages with the top of the disc 21, and the arc surface 233 blocks the opening of the limiting hole 14, preventing the mud from entering the inside of the roller.

[0037] Please see Figure 1 and Figures 5 to 6 A connecting rod 20 is fixedly connected to the center of each of the multiple discs 21. One end of the connecting rod 20 is fixedly connected to a handle 24. One end of the cylindrical nail 23 passes through a fixing sleeve 25. A disc screw 260 is threaded onto the fixing sleeve 25. One end of the disc screw 260 is rotatably connected to a locking block 261. The disc screw 260 and the locking block 261 constitute a positioning element 26. The bottom surface of the locking block 261 presses against the protrusion 200 provided on the connecting rod 20. The locking block 261 is limited in the second limiting groove 250 opened in the fixing sleeve 25.

[0038] Tightening the disc screw 260 can push the locking block 261 to press the protrusion 200 and lock the connecting rod 20.

[0039] Please see Figure 2 and Figure 4 The roller 1 has through holes 12 arranged in a ring array to facilitate the insertion of the connecting rod 20. The roller 1 also has a placement slot 13 for placing the disc 21 extending from the through hole 12. The placement slot 13 is connected to the limiting hole 14 of the limiting cylindrical nail 23.

[0040] Among them, the limiting hole 14 constrains the cylindrical nail 23 to only move vertically up and down, without horizontal offset.

[0041] Please see Figure 8 It also includes a roller 1, on which multiple triangular iron pillars 10 in strip-shaped structures are welded to the outer circumference of the roller 1. The cylindrical nails 23 can also be welded at equal intervals around the outer circumference of the roller 1. The roller 1 is also mounted on a rotary tiller.

[0042] Among them, the rotary tiller first levels the seed plot, and the roller 1 completes the ditching and fixed-point planting hole shaping operations in sync with the tractor.

[0043] The distance between two adjacent sets of height adjustment components is 10cm, and the maximum protrusion height of the cylindrical nail 23 is between 2cm and 5cm.

[0044] This allows for adaptation to standard plant spacing and planting hole depth for wheat, corn, peanut, and soybean breeding.

[0045] The implementation principle of a seeding and furrowing roller device for crop breeding according to an embodiment of this application is as follows:

[0046] Working principle 1: Cylindrical nail 23 uniform height adjustment and locking ( Figure 1 , Figure 3 , Figure 5 , Figure 6 ):

[0047] The operator turns the outer handle 24, which drives the coaxial connecting rod 20 to rotate synchronously. All the discs 21 on the connecting rod 20 rotate synchronously. The first limiting groove 210 inside the disc 21 shifts its position as the disc rotates, thereby causing the positioning wheel 22 to move synchronously. The positioning wheel 22 drives the cylindrical nail 23 to be restricted by the roller limiting hole 14, and can only move up and down in the vertical direction. The height needs to be referenced by the scale value 232.

[0048] After adjusting the cylindrical nail 23 to the height corresponding to the scale value 232 according to the needs of the breeding crop, screw the disc screw 260. The disc screw 260 pushes the locking block 261 downward. The locking block 261 moves down along the second limiting groove 250 to press the outer wall protrusion 200 of the connecting rod 20. The connecting rod 20 is locked by friction, and the angle of the disc 21 is fixed, so as to achieve the height locking of the cylindrical nail 23. There is no height deviation during the operation.

[0049] Multiple sets of adjustment components for independent interval control ( Figure 2 , Figure 4 , Figure 7 ):

[0050] Each set of height adjustment components on roller 1 is independent of each other, and the connecting rods 20 of each set are not linked. During the breeding comparison test, a single set of throttles 24 can be rotated to retract the corresponding cylindrical nails 23, while the other components keep the cylindrical nails 23 protruding downwards, so as to achieve inter-row fixed-point pressing of holes. Alternatively, all components can be lowered simultaneously to form uniform planting holes in the whole row.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
