Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a grass collection device for a mower, and is configured to efficiently send grass clippings to a grass collection container through a chute with a grass clippings feed device. .

Conventional technology> A grass clipping feeder is installed on the grass clipping outlet side on either the left or right side of the mower deck, and the grass clippings are cut by the mower.

A grass collecting device in which grass is fed to a rear grass collecting container through a chute by this feeding device is already known.

<Problems to be Solved by the Invention> However, conventionally, the feeding device and the chute are arranged substantially parallel to the entire traveling direction of the chute, and the wheat end of the chute is bent inward to connect it to the grass collecting container. This has the drawback that the bent portion causes grass to become clogged, making it impossible to feed grass clippings efficiently.

The invention was provided with the aim of solving these conventional problems.

Means for Solving the Problems> The present invention, as a specific means for solving the problems of the prior art, provides a grade that rotates around a horizontal axis in correspondence with the grass clippings discharge ports on the left and right sides of the mower deck. In a mower grass collecting device which is provided with a grass clippings feeding device and which feeds the grass clippings through a chute to a grass collecting container at the rear, the grass clippings feeding device and the chute are arranged so that the rear side is on the center side of the mower. It is provided so as to be inclined in plan view with respect to the traveling direction so as to be deviated.

For use> A cut grass feeding device (specifically, a mower (81 passage (11) to a cut grass discharge port 1) sucks in the cut grass discharged from the mower (81 passage (11)) and sends the chute I441 by means of a prydle that rotates on the horizontal axis.
Grass collection bag after 1451! 51). In this case, the feeding device (2), the shoe) i441+451 is inclined with respect to the advancing direction in plan view so that the rear side is deviated inward, so that the grass clippings are transferred to the center side of the grass collecting bag 1511. Despite sending it.

There is no need for a bent portion in the chute 1441451, and grass clippings can be sent efficiently.

An air outlet is provided on the upper side of the case in a tangential direction that slopes rearward and upward at an angle of about 45 cm when viewed from the side.

The air outlet 143VC has a linear chute (441 attached to it).The upper end of the outlet 1447 is connected to a charging duct (451).

The feeding device (2) and the chute 1441 are provided so as to be inclined in plan view with respect to the traveling direction so that their rear sides are deviated from the mower center side 1c. That is, the case E() is inclined with respect to the direction of movement so that the horizontal axis 124J of the feeder is substantially parallel to the feeding direction of the grass clippings passage (11). A chute 144I is arranged at approximately the direction angle &.

As shown in FIG. 1 and FIG. 2, a pair of left and right cylindrical brackets 4G are provided at the rear end of the tractor body ILL, and a support frame [47
1 pillar! 481 is inserted into the insertion/extraction position from above and secured with a pin. Support frame t4711/i Consists of a pair of left and right supports t481 and a horizontal rod and a cap installed horizontally at the upper ends of the supports t481.

On the side rod side, there is a pair of left support rods v5+Jj that protrude rearward.
Two sets are provided, and a grass collection bag 1511 as a grass collection container is detachably attached to the pair of support rods ψ.

The grass collecting bag is made of canvas, plastic sheet, net material, etc., and a mouth frame fi21 made of a trowel-like cylinder is inserted and fixed to the periphery of the opening at the upper end. Both ends of the trowel-shaped opening #1521 are inserted between the pair of support rods from behind the insertion/extraction opening VC.

In other words, when the grade rotates, the grass clippings that have been sent to the lower discharge side of the passage 1111 are fed into the case through the suction port (b). It is sucked in, rotates along the same plane of the case's entorhinal surface, and is fed into the grass collection bag (2) through the discharge port (431).

You can collect grass at the same time as mowing.

In this case, the grass clippings are fed from the passage (111) and sucked in from the suction port along the horizontal axis C24JVc.
