FR2502889A1 - Clipping-removing device for mower - has pneumatic hose connected to collection bag which is mounted on pivotal cradle on wheeled chassis - Google Patents

Abstract

The herbaceous plant mower has a large bag (11) which is mounted on a cradle (17) pivotally mounted on a wheeled chassis so that it can be tipped over to discharge its contents. The bag is supported by a series of straps (27,28,29,30) which pass over the top and are connected to the cradle. The sack is tilted about an axis which is parallel to the longitudinal axis of the vehicle. The cradle is pivoted by an hydraulic jack mounted on the vehicle chassis. The pneumatic suction device (10) picks up the clippings and feeds them into the open upper end of the bag.

Description

Technical area.

 The present invention relates to improvements to mowers or mowers of herbaceous plants in which the grass is transported pneumatically in a conduit between the mowing member and the upper part of a removable bag of cut grass.

Problem.

 It has to mow or mow the plants and grasses on horizontal parts and to recover the mowed products for the purpose of a later use, in particular for animal feed.

 More specifically, the mower or mower of the invention is intended to treat the horizontal parts of road curbs with direct recovery of the product.

State of the prior art and drawbacks.

 Currently, no mechanical pickup is done when mowing grass on the side of roads.

Mown grass, mostly by disc mowers, is left behind. Self-loading trailers typically agricultural use are not suitable for this kind of work because they risk picking up foreign elements that clutter the edge of roads and highways and, the sides of roads have frequent unevenness of the soil detrimental to existing equipment .

 Furthermore, there are known small lawn mowers in which the mowed grass is transported pneumatically to an openwork container or a bag from which it is periodically extracted. However, these mowers, even the most important, are insufficient to treat the large areas bordering the roads and, in particular, the containers for collecting mowed grass are much too small and it is understood that they are not suitable for picking up large volumes and weights of grass.

 The present invention is intended to remedy these drawbacks.

Statement of the invention.

 In general, the mower or mower of the invention is mainly characterized by the fact that the large bag includes means for starting a lifting device and rests on a supporting cradle allowing it to be discharged laterally mechanically.

 More specifically, the bag rests on a cradle pivoting about an axis parallel to the longitudinal axis of the vehicle, said cradle having one side, or drop side, which can be folded down so as to be able to release the bag which has a dimension compatible with the maximum gauge. road vehicles, i.e. 2.20 m to 2.40 m.

 Preferably, the cradle pivots about a parallel and longitudinal axis under the effect of a hydraulic cylinder.

 In a first version, the bag holder cradle rests on the rear of the vehicle comprising the mowing members and constituting the whole of the apparatus.

 In a second version, the bag-carrying cradle rests on a trailer of the mower or mower, the connection of the flexible bag being made in line with the positive coupling device of the trailer by a flexible and elastic cuff.

 According to a preferred embodiment, the mowing device is arranged at the extreme front of the device and it is wider than the width of the vehicle, the front axle of which comprises two wheels which are fixed around a vertical axis and whose rear axle has a single steering wheel.

 In order to mow beyond a side of the vehicle, the mowing device is offset to one side of it. I1 furthermore comprises means for adjusting the cutting height, vertical and parallel adjustment <the rigid axle, and lateral tilt adjustment relative to the rigid axle, using hydraulic controls, to counter the inconsistent unevenness existing between the right front wheel and left front wheel.

 The dry recovery of mowed and mowed products are particularly resistant and are however breathable. To easily reach this compromise, they are reinforced by straps which lead to at least two mooring eyes. The bags have two mooring points. One at mid-height for the recovery of the full bag placed on the ground. The other located at the bottom of the bag and used to empty it.

Solution to the problem, advantages and industrial result.

 The mower or mower of the invention has the advantage of being specialized in a precise job which is that of mowing and mowing the grass located at the roadside. It also has the advantage of being able to recover an energy source or food products Up to 1 practically reduced due to the low yield resulting from the mechanical: -; mechanical ens currently available.

 The invention will be better understood with the aid of the description below which gives two non-limiting examples of practical embodiment thereof and which are illustrated by the accompanying drawings.

Description of an embodiment.

 The apparatus of the invention shown in the drawings essentially consists of a mower-mower - (1) which further comprises a bag-carrying trailer (2).

 The mower mower (i) rests on front wheels (3) and (4), with rigid axle, and on a rear wheel (5) which is steered, held in a fork (S) which can pivot around a vertical axis ( 7). The cockpit (@) is located at the front, above the wheel (3), while the mower (') is placed at the far front and is of a known type which propels the grass up in a sheath (10) for guiding and evacuating to a large bag (11) passing through an elastic and flexible cuff (12) these two qualities are necessary depending on the joint ( 13) between the mower-mower (1) and the trailer (2) which causes pivoting about a vertical axis, as well as according to the unevenness of the ground which causes either a separation or an approximation of the sheath (10 ) and the bag (11).

 It goes without saying that the cuff (12) is practically plumb with the joint (13).

 The front wheels (3) and (4) of the mower mower (1) are driven and there is provided a signaling member (14), such as a rotating beacon, on the roof of the cabin (6).

 The bag-carrying trailer (2) rests, in addition to the towing linkage (13), on two wheels (15) and (16).

 It essentially comprises a bag-carrying cradle (17) which is capable of pivoting around axes (18) and (19) parallel and longitudinal. The pivoting cradle (17) is completed by a fixed support (38) arranged opposite the pivoting side panel (26) to pivot part of the cradle (17) on the right side by folding down the side panel (26).

 The bag (11) has many reinforcements such as the straps ~ (27), (28) and (29), in particular. These straps lead to two lashing eyes (30), (37) which allow the subsequent handling of the bag, in particular when it has been unloaded on the side of the road and which must be raised for the wear on a lifting vehicle - One of these eyes (30) is used for the recovery of the full bag placed on the ground. The other () 7), located at the bottom of the bag, serves to empty it. This bag has indeed a maximum diameter and length corresponding to the maximum width standards in force for road vehicles. Its diameter is of the order of 2.20 m to 2.40 m.

 The mower (9) or mowing device is arranged at the extreme front of the apparatus and is wider than the width of the vehicle to obtain an optimum mowing surface. A special feature of this mowing device (9) is that it is offset to the right of the vehicle, as clearly seen in Figure 2, so as to mow well beyond the wheel (4) to be able to mow the the entire side without risking that said wheel (4) gets bogged down in the ditch.

 The mowing device (9) is not only adjustable in height so that its axis moves parallel to itself vertically, but it can tilt laterally to adapt to the varying elevations existing between the front right and left wheels. The movements are controlled by hydraulic cylinders not shown.

 We have described here an apparatus composed of a mower mower (1) pulling a trailer (2), which has the advantage of great maneuverability and makes it easier to clear the apparatus stuck in uncoupling it, but it will without saying that we can provide the same device in a single vehicle where rear would include the cradle (17) to receive the bag (11).
