Description

Crop harvesting equipment for tractors

[0001] The present invention relates to a crop harvesting device for a tractor, and more particularly, to a crop harvesting device for a tractor that can improve crop feeding performance by adjusting the width and height of an inlet portion when cutting crops and feeding the cut crops into a treatment tank, thereby minimizing stagnation and clogging of the crops.

[0002] In general, various auxiliary agricultural tools, such as detachable agricultural harvesters, are used with power-driven agricultural machines such as cultivators and tractors to increase work efficiency.

[0003] These agricultural harvesters can save labor when harvesting crops and can harvest grains, vegetables, and fruits, depending on the type.

[0004] These agricultural harvesters are being developed with a structure that has various functions, such as not only cutting down crops, but also bundling the cut crops and threshing them at the same time.

[0005] Conventional agricultural harvesters can harvest various varieties of crops, including corn, sudangrass, and ryegrass, but they have the problem of crops frequently becoming clogged due to the fixed width of the inlet without considering the size, thickness, and properties of the crops.

[0006] In addition, conventional agricultural harvesters have a problem in that when thin-stemmed crops such as ryegrass and whole barley are brought in, the crops spread in the height direction, resulting in reduced bringing-in performance.

[0063] Additionally, the lower end of the inlet fixing plate (1321) can be connected to the second collecting plate (1333) of the transport collecting unit (133). The inlet fixing plate (1321) can partially wrap around the rear of the second transport blade (1312) and the second transport rotating drum (1314) by being connected to the second collecting plate (1333).

[0064] As shown in FIGS. 9 and 10, the inlet fixing plate (1321) may further include a pair of plate connecting pieces (13212) and a piece insertion hole (13213).

[0091] FIG. 11 is a perspective view illustrating a roller module of a crop harvesting device for a tractor according to an embodiment of the present invention.

[0092] Referring to Fig. 11, a roller module (140) is coupled to a first coupling portion (111) and is positioned between a pair of inlet width adjusting portions (132) to press down crops introduced into a transport portion (131) in the height direction. The roller module (140) may include a roller fixing portion (141) and a roller portion (142).

[0093] The roller fixing part (141) can be connected to the first coupling part (111) with one end and the other end centered around the second coupling part (112). The roller fixing part (141) can be connected to the roller part (142) to fix the roller part (142) to a predetermined position of a pair of inlet width adjusting parts (132). The roller fixing part (141) can include a first roller fixing plate (1411), a roller fixing extension plate (1412), and a second roller fixing plate (1413).

[0094] The first roller fixing plate (1411) can be coupled to the first connecting portion (111). A roller fixing extension plate (1412) can be extended from the first roller fixing plate (1411).

[0095] The roller fixing extension plate (1412) can be extended from the first roller fixing plate (1411). The roller fixing extension plate (1412) can be formed in a T-shape, but is not limited thereto, and any shape can be adopted as long as it has a structure that can position the roller portion (142) at a certain height.

[0096] The second roller fixing plate (1413) can be extended from the roller fixing extension plate (1412) and coupled to the first coupling portion (111).

[0097] In one embodiment, the first roller fixing plate (1411) and the second roller fixing plate (1413) may be detachably installed on the first coupling portion (111). For example, when the first coupling portion (111) is formed of a magnetic material, the first roller fixing plate (1411) and the second roller fixing plate (1413) may be formed of a magnetic material and may be detachably installed on the first coupling portion (111).

[0098] The roller unit (142) can be connected to the roller fixing unit (141) and placed between a pair of inlet width adjusting units (132). The roller unit (142) can be adjusted in height between the pair of inlet width adjusting units (132) to press down crops introduced between the pair of inlet width adjusting units (132). The roller unit (142) can include a pair of height adjusting members (1421), a pair of roller rotating members (1422), and a roller member (1423).

[0099] A pair of height adjusting members (1421) may have one end connected to the first surface of a roller fixing extension plate (1412) and the other end connected to the other end of a pair of roller rotating members (1422), respectively. The pair of height adjusting members (1421) may be formed to be length-adjustable, and may push or pull the pair of roller rotating members (1422) according to the length adjustment. For example, the pair of height adjusting members (1421) may be a gas spring, a compression spring, or the like.

[0100] A pair of roller rotation members (1422) may have one end connected to the second surface of the roller fixing extension plate (1412) and the other end connected to each of the other ends of a pair of height adjustment members (1421). Here, the second surface may be a surface adjacent to the first surface.

[0101] A pair of roller rotation members (1422) can rotate from a roller fixing extension plate (1412) according to the length adjustment of a pair of height adjusting members (1421). That is, one end of a pair of roller rotation members (1422) can be rotatably connected from a roller fixing extension plate (1412), and the other end of a pair of roller rotation members (1422) can be rotatably connected from a pair of height adjusting members (1421). In this connection state, when a pair of roller rotation members (1422) is pushed or pulled in the height direction according to the length adjustment of a pair of height adjusting members (1421), the pair of roller rotation members (1422) can rotate from a roller fixing extension plate (1412) to adjust the height of the roller member (1423).

[0102] At this time, a pair of roller rotation members (1422) includes a bending portion (14221) between one end and the other end, and a roller member (1423) can be axially connected to the bending portion (14221).

[0103] A roller member (1423) may be arranged between a pair of roller rotation members (1422) and may be axially connected between one end and the other end of each of the pair of roller rotation members (1422). That is, the roller member (1423) may be rotatably connected to a bending portion (14221) of the pair of roller rotation members (1422).

[0104] The height of the roller member (1423) can be adjusted by moving a pair of roller rotation members (1422) in the height direction by a pair of height adjustment members (1421). Here, the roller member (1423) is arranged between a pair of inlet width adjustment parts (132), and the height is adjusted between the pair of inlet width adjustment parts (132), so that the crops introduced between the pair of inlet width adjustment parts (132) can be pressed.

[0105] At this time, the roller member (1423) is rotatably connected to the bending portion (14221) of a pair of roller rotating members (1422), so that when the crop is introduced, it rotates and pushes the crop into the crop storage space (not shown) inside the tractor.

[0106] FIG. 12 and FIG. 13 are plan views for explaining the operation of a crop flow and inlet width control unit using a crop harvesting device for a tractor according to an embodiment of the present invention.

[0107] Referring to FIGS. 12 and 13, the direction of movement of the crop is explained. The crop can be cut by the cutting portion (121) when guided by the guide portion (122) according to the movement of the tractor (not shown) (P1).

[0108] The crop can move to the rear end of the cutting unit (121) while rotating according to the rotation direction of the cutting unit (121) (P2). Here, the rotation direction of the cutting unit (121) may be different for each cutting unit (121) as shown in the drawing, and the direction shown in the drawing is intended to capture the crop as much as possible into the transport module (130), but is not intended to be limited thereto.

[0109] The crops can be moved to the rear end of the cutting section (121) and then captured at the center of the rear end of the cutting section (121) and moved to the transport module (130) (P3). At this time, depending on the amount and size of the crops, the width adjustment section (132) of the transport module (130) can be adjusted, and the roller section (142) of the roller module (140) can be adjusted in height.

[0110] Although the present invention has been described above with reference to one embodiment, it will be understood by those skilled in the art that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
