Description

Technical Field

[0001] The invention relates to the field of transplanting machines, in particular to a slitting roller of a transplanting machine. Background Art

[0002] During the use of the transplanter, it is necessary to use a conical disc to open furrows on the bed surface, and a slitting disc to open slits for planting seedlings; as in the application number: 202210788612.6, the roller body of the conventional slitting roller is a cylinder with a closed outer circumference, and the conical disc and the slitting roller are installed on the cylinder;

[0003] During use, the roller body contacts the bed surface and compacts the land, causing the planting seams cut by the cutting disc to be too tight, resulting in a long seedling acclimatization period and seedling stiffness problems.

[0004] In summary, how to avoid the problem of too high planting seam tightness during the use of the slitting roller has become an urgent problem that researchers in this field need to solve. Summary of the invention

[0005] The technical problem to be solved by the present invention is: how to avoid the problem of too high planting seam compactness during the use of the slitting roller;

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The present invention is a slitting roller for a transplanter, comprising: a roller body; two conical discs arranged opposite to each other and used for ditching, which are fixedly arranged in the middle of the roller body; a plurality of slitting discs, which are arranged on both sides of the roller body; wherein a cavity is arranged on the roller body at the slitting discs;

[0008] In this solution, two opposite conical disks are arranged in the middle of the roller body, and a plurality of slitting disks are arranged on both sides of the roller body; compared with the traditional cylindrical roller body, the roller body is provided with a cavity, so that during the slitting process, the land will be squeezed and moved toward the cavity, so that the land will not be compacted, thus avoiding the problem of too high planting seam tightness during the use of the slitting disk, and also avoiding stunted seedlings.

[0009] In order to explain the specific structure of the roller body, the roller body used in the present invention includes: two disks arranged opposite to each other, and the outer sides of the disks are provided with shaft heads; a plurality of rods arranged in an annular manner, and both ends of the rods are connected to the corresponding disks, and the cavity is formed between two adjacent rods;

[0010] The two discs have a plurality of rods arranged circumferentially, and cavities are formed between the rods. The soil is squeezed and moves toward the cavities between the rods.

[0011] Since the connection strength between the slitting disk and the rod bodies arranged at equal intervals is insufficient, in order to increase the connection strength of the slitting disk, the roller body of the present invention further includes: a plurality of arc-shaped connecting plates for connecting the slitting disk to the plurality of rod bodies, the plurality of arc-shaped connecting plates are arranged circumferentially, and each of the arc-shaped connecting plates connects two adjacent rod bodies;

[0012] The two ends of the arc-shaped connecting plate correspond to the welding rod body, and the outer surface of the arc-shaped connecting plate is welded to the inner circle of the slitting disk. By setting the arc-shaped connecting plate, the connection area of ​​the slitting disk is increased, and the connection strength between the slitting disk and the roller body is increased.

[0013] In order to loosen the soil with the roller during the slitting process of the slitting disc and avoid compaction of the soil, the present invention adopts a first arc-shaped groove for accommodating the end portion of the rod body provided on the circumference of the disc; the inner ring of the slitting disc accommodates the second arc-shaped groove of the end portion of the rod body; the top of the slitting disc is higher than the outer peripheral wall of the disc and the outer surface of the arc-shaped connecting plate;

[0014] The lower part of the rod body is installed in the first arc groove of the disc, and the upper part of the rod body is installed in the second arc groove, so that the top of the rod body protrudes from the outer surface of the arc connecting plate. When the slitting disc is inserted into the soil, the rod body acts on the surface of the soil. When the roller body rotates, multiple rod bodies act on the soil surface in turn, thus forming a loose soil structure on the surface and avoiding soil compaction.

[0015] In order to ensure that the soil at the opening is compacted when trenching, the present invention adopts a rolling sleeve provided at the roller body for mounting the conical disk;

[0016] The outer surface of the rolling sleeve is a closed structure. When the rolling sleeve acts on the soil surface, it can compact the soil. When the conical disc digs trenches, the compacted soil will not collapse.

[0017] In order to ensure that the soil at the slit is compacted during the slit process, the width of the arc-shaped connecting plate is greater than the thickness of the slit disc in the present invention;

[0018] The two ends of the arc-shaped connecting plate protrude from the two sides of the slitting disc, so that when the slitting disc is inserted into the soil, the arc-shaped connecting plate acts on the soil surface to make the soil on both sides of the slitting disc compact and prevent the seam from collapsing after slitting.

[0019] The beneficial effects of the present invention are as follows: the present invention is a slitting roller of a transplanter, wherein two opposite conical disks are arranged in the middle of the roller body, and a plurality of slitting disks are arranged on both sides of the roller body; compared with a traditional cylindrical roller body, the roller body is provided with a cavity, so that during the slitting process, the soil will be squeezed and moved toward the cavity, so that the soil will not be compacted, thereby avoiding the problem of too high planting seam tightness during the use of the slitting disk, and also avoiding stunted seedlings.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0026] like Figure 1 As shown, the present invention is a slitting roller of a transplanter, comprising: a roller body 1; two conical discs 2 arranged opposite to each other and used for ditching, which are fixedly arranged in the middle of the roller body 1; a plurality of slitting discs 3, which are arranged on both sides of the roller body 1; wherein a cavity 4 is arranged on the roller body 1 at the slitting discs 3;

[0027] In this solution, two opposite conical disks are arranged in the middle of the roller body, and a plurality of slitting disks are arranged on both sides of the roller body; compared with the traditional cylindrical roller body, the roller body is provided with a cavity, so that during the slitting process, the land will be squeezed and moved toward the cavity, so that the land will not be compacted, thus avoiding the problem of too high planting seam tightness during the use of the slitting disk, and also avoiding stunted seedlings.

[0028] like Figure 1 As shown, in order to illustrate the specific structure of the roller body, the roller body 1 adopted in the present invention includes: two disks 11 arranged opposite to each other, and the outer side surfaces of the two disks 11 are provided with shaft heads 12; a plurality of rod bodies 13 arranged in an annular manner, and both ends of the rod bodies 13 are connected to the corresponding disks 11, and the cavity 4 is formed between two adjacent rod bodies 13;

[0029] The two discs have a plurality of rods arranged circumferentially, and cavities are formed between the rods. The soil is squeezed and moves toward the cavities between the rods.

[0030] like Figure 1 , 3As shown, since the connection strength between the slitting disc and the rod bodies arranged at equal intervals is insufficient, in order to increase the connection strength of the slitting disc 3, the roller body 1 of the present invention further includes: a plurality of arc-shaped connecting plates 14 for connecting the slitting disc 3 with the plurality of rod bodies 13, the plurality of arc-shaped connecting plates 14 are arranged circumferentially, and each arc-shaped connecting plate 14 connects two adjacent rod bodies 13;

[0031] The two ends of the arc-shaped connecting plate correspond to the welding rod body, and the outer surface of the arc-shaped connecting plate is welded to the inner circle of the slitting disk. By setting the arc-shaped connecting plate, the connection area of ​​the slitting disk is increased, and the connection strength between the slitting disk and the roller body is increased.

[0032] like Figure 1 , 3 As shown, in order to achieve loosening of the soil by the roller during the slitting process of the slitting disc and avoid compaction of the soil, the present invention adopts that the disc 11 is provided with a first arc groove 111 in the circumferential direction for accommodating the end portion of the rod body 13; the inner ring of the slitting disc 3 accommodates the second arc groove 31 of the end portion of the rod body 12; the top of the slitting disc 3 is higher than the outer peripheral wall of the disc 11 and the outer surface of the arc connecting plate 14;

[0033] The lower part of the rod body is installed in the first arc groove of the disc, and the upper part of the rod body is installed in the second arc groove, so that the top of the rod body protrudes from the outer surface of the arc connecting plate. When the slitting disc is inserted into the soil, the rod body acts on the surface of the soil. When the roller body rotates, multiple rod bodies act on the soil surface in turn, thus forming a loose soil structure on the surface and avoiding soil compaction.

[0034] like Figure 2 As shown, in order to ensure the compaction of the soil at the opening when trenching, the present invention adopts a rolling sleeve 15 provided at the roller body 1 for mounting the conical disc 2;

[0035] The outer surface of the rolling sleeve is a closed structure. When the rolling sleeve acts on the soil surface, it can compact the soil. When the conical disc digs trenches, the compacted soil will not collapse.

[0036] like Figure 1 As shown, in order to ensure that the soil at the slit is compacted during the slit process, the width of the arc-shaped connecting plate 14 is greater than the thickness of the slit disc 3 in the present invention;

[0037] The two ends of the arc-shaped connecting plate protrude from the two sides of the slitting disk, so that when the slitting disk is inserted into the soil, the arc-shaped connecting plate acts on the soil surface to make the soil on both sides of the slitting disk compact, thereby avoiding the collapse of the slit after slitting; that is, the cavity between the two slitting disks and the rotation of the rod body act on the soil to avoid the compaction of the soil, and the contact between the arc-shaped connecting plate and the soil near the slitting disk keeps the soil compacted, and there is no risk of collapse after slitting.

[0038] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
