Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a lawn harvester of a type that conveys grass cut in a grid pattern to a collecting section on a vehicle body using a pick-up transfer device and packs a plurality of grass collected in the collecting section. It is about.

[0002]

[Prior Art]

 Lawn harvesters of the type described above are already known, for example, from Japanese Patent Laid-Open Nos. 61-1307 and 61-1308. However, the conventional one is transported to the transport end portion of the belt conveyor that places and lifts and transports a lawn cut in a square shape, or a lawn that is transported in a belt shape and cut in a square shape on the way. A reversing mechanism that reverses every other lawn that comes up is provided, and the lawn reversed by the reversing mechanism is repeatedly stacked on the lawn already placed in the collecting section, and the root side of the lawn is repeated. And the root side and the stem side and the stem side are stacked together.

[0003]

[Problems to be solved by the device]

 Conventional lawn harvesters require a reversing mechanism that reverses every other lawn that is conveyed in order to stack the lawn root side and root side and the stem side and stem side together. The lawn is liable to be damaged or collapsed when it is turned over by the mechanism, and since it is not possible to stack neatly unless the grass is turned over in a timely manner, the device structure is complicated to ensure timing accuracy. There was a problem that it turned into. The present invention has been made in view of such a problem, and an object thereof is to eliminate the need for a reversing mechanism for reversing every other lawn, instead of a lawn side and a root side, or a lawn. The aim is to obtain a lawn harvester that has a simple structure and can prevent damage and collapse of the lawn by changing the posture so that the stalk side and the stalk side can be adjusted and feeding the stalk side.

[0004]

[Means for Solving the Problems] That is, the lawn harvester of the present invention comprises a pair of left and right scooping bodies (3) (mounted on the front ends of the frames (2) extending from the traveling vehicle body (1). 4) and two sets of conveyor endless belts (6) (7), (6) (which are obliquely installed from the rear position of each scooping body (3) (4) toward the rear collecting section (5) 7) and the pick-up conveying device (P) composed of the guide bodies (8) and (9) provided corresponding to the conveying endless belts, one set or plural sets are provided in the lateral direction of the vehicle body. Of the four transport endless belts in the pickup transport device (P), two inner transport endless belts (6) and (6) adjacent to each other and two outer transport endless belts ( 7) The (7) and (7) are installed with different heights so that the height difference between the two becomes larger toward the end of the conveyance, and they are lifted and conveyed by a set of pickup conveyors (P). It is characterized in that the two mat-shaped lawns (T1) and (T2) are fed to the collecting section (5) after changing their postures in a combined manner during the lifting and conveying process.

[0005]

[Operation and effect of the device]

 In the lawn harvester configured as described above, the pickup transfer device (P) advances as the traveling vehicle body (1) advances, and a pair of left and right scooping bodies (3) (mounted on the front end of the pickup transfer device (P)). 4) scoops up the mat-shaped lawn (T1) (T2) on the ground, respectively, and transports endless belts (6) (7), which are connected to the rear of each scooping body (3) (4), (6) Supply to the starting point of the transportation in (7). The mat-shaped lawn (T1) (T2) supplied to the transport start ends of the transport endless belts (6), (7), (6), (7) is the transport endless belts (6), (7), (6) (7). ) Of the four endless belts (6), (7), (6) and (7), the two endless belts (6) which are adjacent to each other inside are conveyed. ) (6) and the two endless conveyor belts (7) (7) located outside them are provided with different heights so that the height difference becomes large toward the end of the conveyor. Therefore, as the transfer progresses, both mat-shaped lawns (T1) and (T2) gradually change their posture into a V-shape due to the cooperative action of the endless belt and the guide bodies (8) and (9), and the collecting section ( At the time of supply to 5), the root side and the root side or the stem side and the stem side will be in a state of matching. In this way, while the two mat-shaped lawns (T1) and (T2) are being lifted and conveyed by the pickup conveying device (P), it is naturally possible that the root side and the root side or the stalk side and the stalk side are aligned with each other. Since the posture is changed so that it is fed to the collecting section (5), the reversing mechanism required in the conventional lawn harvester is unnecessary, and the device is simplified accordingly. In addition, since every other mat-shaped lawn is not forcibly inverted by the reversing mechanism, the lawn is less scratched or collapsed, and the stacking is also well-aligned so that a uniform stacking collection can be performed. It was supposed to be.
