Description

Improved structure of multi-disc mower

Technical Field

The utility model belongs to the technical field of pasture harvesting equipment, and particularly relates to an improved structure of a multi-disc mower.

Background

The grass is harvested by a multi-disc mower, and then the grass strips are formed and aired; lodging can occur due to seed reasons, strong wind environment and other factors in the grass growing process. The situation of missed cutting occurs in the lodged pasture area during harvesting, because the lodged pasture is lower than the action position of the cutter of the multi-disc mower, and the mowing disc cannot be further lowered, otherwise, the cutter is easy to damage; lodging pasture during harvesting can also lead the cutter not to act on the root of the pasture, so that the residual length of the stubble is increased, and the short cutting condition occurs; the missing cutting and the short cutting of the pasture result in the yield reduction of the pasture, and the manual treatment increases the cost of harvesting the pasture.

Disclosure of Invention

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the improved structure of the multi-disc mower comprises a mower frame and a cutter arranged on the mower frame, and is characterized by further comprising a grass supporting mechanism which is arranged on the mower frame and positioned in front of the cutter; the grass supporting mechanism comprises a lifting adjusting mechanism arranged on the grass cutting rack and a guiding and supporting mechanism arranged on the lifting adjusting mechanism.

Further, the guide lifting mechanism comprises a plurality of connecting vertical rods which are transversely arranged at intervals and V-shaped guide bodies which are arranged on each connecting vertical rod; the V-shaped guide body is in a toppling shape, and two free ends of the V-shaped guide body are in conical shapes.

Further, a pulley is arranged at the V-shaped groove formed by the V-shaped guide body.

Further, the lifting adjusting mechanism comprises a connecting frame arranged on the mower frame, a U-shaped guide frame arranged below the connecting frame, and a screw rod hinged in the middle of the U-shaped guide frame and in threaded fit with the connecting frame; the U-shaped guide frame is provided with two lever arms and longitudinally penetrates through the connecting frame and is in sliding fit with the connecting frame, a hand wheel is arranged at the top end of the screw rod, and the connecting upright rod is fixed on the lower side of the U-shaped guide frame.

The utility model has the following effects:

according to the utility model, by utilizing the special structural design of the V-shaped guide body, the lodged pasture straw is supported by the V-shaped guide body to a certain height in the advancing process of the multi-disc mower, so that the cutter can cut pasture and effectively cut the root of the pasture, the conditions of missed cutting and short cutting caused by lodging of the pasture are avoided, and the problem of yield reduction is avoided.

Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, a multi-reel mower improved structure; the improved structure solves the problem of missed cutting and short cutting caused by lodging of pasture by adding components on the basis of the existing multi-disc mower. The multi-disc mower comprises a mower frame and a cutter 1 arranged on the mower frame; the mower frame has a connecting base 2, and a plurality of cutters 1 are arranged transversely and connected to the connecting base 2. The key point of the improved structure is that a grass supporting mechanism is additionally arranged on the connecting bottom plate 2.

The grass supporting mechanism comprises a lifting adjusting mechanism arranged on the connecting bottom plate 2 of the grass cutting rack and a guiding and supporting mechanism arranged on the lifting adjusting mechanism.

The lifting adjusting mechanism comprises a connecting frame 3, a U-shaped guide frame 4 and a screw 5. The connecting frame 3 is in an inverted U shape and is fixed on the connecting bottom plate 2; the U-shaped guide frame 4 is positioned below the inner side of the connecting frame 3, and the U-shaped guide frame 4 is provided with two lever arms and longitudinally inserted on the connecting frame 3 and is in sliding fit with the connecting frame 3; one end of the screw 5 is hinged to the middle of the U-shaped guide frame 4 and is longitudinally arranged, a hand wheel 6 is arranged at the top end of the screw 5, and the screw 5 is in threaded fit with the connecting frame 3. The U-shaped guide frame 4 can be lifted and moved relative to the connecting frame 3 by rotating the screw 5.

The guide lifting mechanism comprises a plurality of connecting vertical rods 7 which are transversely arranged at intervals and V-shaped guide bodies 8 which are arranged on each connecting vertical rod 7. The top end of the connecting upright rod 7 is connected to the lower side of the U-shaped guide frame 4; the V-shaped guide body 8 is in a tilting shape, and the opening direction faces the advancing direction of the multi-disc mower; the two free ends of the V-shaped guide body 8 are conical, so that the cutting effect on the lifting process of the pasture rod is avoided; the V-shaped groove formed by the V-shaped guide body 8 is easy to cut grass rods, so that the pulley 9 is arranged at the V-shaped groove, and the pulley 9 is embedded into the V-shaped groove, so that the notch of the V-shaped groove is smoothly transited.

The application method and the working principle of the utility model are as follows:

when the utility model is applied, the agricultural tractor pulls and controls the action of the multi-disc mower. Before harvesting, the position of the V-shaped guide body 8 relative to the cutter 1 needs to be adjusted, and the specific adjustment operation is as follows: the screw 5 is rotated by the hand wheel 6, the U-shaped guide frame 4 is driven by the screw 5 to ascend and descend relative to the connecting frame 3, the lowest point of the V-shaped guide body 8 is enabled to be close to or partially embedded into the ground during adjustment, and meanwhile, the V-shaped notch of the V-shaped guide body 8 is enabled to be higher than the lowest cutting point of the cutter 1, and is preferably higher than 3-8 cm. In the harvesting process, the lodged pasture rods are lifted by the V-shaped guide bodies 8 from the ground to be embedded into the V-shaped grooves of the V-shaped guide bodies 8 and lifted to a certain height, so that the cutter 1 can cut the roots of the pasture; the V-shaped groove of the V-shaped guide body 8 is easy to store the pasture which is gathered and lodged, and the conical end part of the V-shaped guide body 8 and the pulley 9 can prevent the pasture from generating cutting action when sliding relative to the V-shaped guide body 8, so that the resistance action of the V-shaped guide body 8 can be reduced. When the pasture is in a non-lodging pasture area, the V-shaped guide body 8 can distribute pasture, and the normal harvesting of the pasture is negatively affected.
