Description

[0001] The invention relates to a device for mowing, scarifying and / or collecting according to the preamble of claim 1.

[0002] Such a device for mowing, scarifying, and / or collecting is described in EP 0 676 128 A1. The materials collected by the device are gathered in a collection container. The collection container is mounted on a frame of the device by means of a lifting and / or tilting mechanism, which rotates the collection container into an emptying position and empties it. Emptying takes place via a discharge opening located in the upper part of the collection container. In the working position, the discharge opening is covered by a cover that is pivotably mounted to the collection container by means of a hinge mechanism. In this known device, a spring element, designed as a gas spring, is arranged between the collection container and the cover.This gas spring automatically opens the cover when the container is swivelled and closes it abruptly when the container is returned to its working position. The closing of the discharge opening by the cover, using the gas spring, is very noisy and loud. This is undesirable in many cases, both because of the noise and the increased wear.

[0003] The invention is based on the objective of achieving a controlled pivoting of the cover with a gentle and quiet closing of the draining opening by the cover.

[0004] This problem is solved according to the invention by the fact that the joint device is located between the upper rear area of ​​the emptying opening and the rear area of ​​the cover, and that the spring element, when moving the collection container from the emptying position to the working position, brakes the cover during the closing process of the emptying opening.

[0005] As a result of these measures, the arrangement of the spring element according to the invention ensures that the cover is gently pivoted into its covering position when the collection container is pivoted into the working position, so that the emptying opening is closed very quietly and in a controlled manner by the cover.

[0006] To gently determine the final opening position of the cover during emptying of the collection container, a spring-loaded stop element is provided in the area of ​​the hinge mechanism. This element acts between the collection container and the cover, defining and limiting the opening of the cover. Thus, in the final phase of the opening process, the spring-loaded stop element gently decelerates the cover into its final position.

[0007] Furthermore, this spring-loaded stop element ensures that, at the beginning of the closing process of the emptying opening by the cover, the cover is pressed towards the closing position immediately upon moving the collection container from the emptying position to the working position, even if it is in an unfavorable position. This is achieved gently by the spring-loaded stop element resting against the cover at the beginning of the closing process and pressing the cover towards its closing position. Thus, the spring element is designed in such a way that it does not actively assist in either opening or closing the emptying opening by the cover.

[0008] The spring-loaded stop element can have a compression spring.

[0009] In one embodiment, the spring element between the collection container and the cover is designed as a gas spring and / or gas damper.

[0010] Further details of the invention can be found in the description of the example and the drawings. The drawings show Fig. 1 the device for mowing, scarifying and / or collecting in side view, wherein the collection container is in working position, Fig. 2 the device for mowing, scarifying and / or collecting in side view, wherein the collection container is in the emptying position, Fig. 3 the device for mowing, scarifying and / or collecting in side view, wherein the collection container is back in working position, but the cover is still in the open position, Fig. 4 The collection container of the device in working position with the cover still in the open position in a perspective view from a slightly oblique front view, Fig. 5 The collection container of the device in working position with the cover still in the open position, in a perspective view from a rear oblique angle and Fig. 6 the arrangement of the spring-loaded stop element between the collection container and the cover with the position of the cover according to the Fig. 3-5 on an enlarged scale and in the view according to Fig. 5.

[0011] The device for mowing, scarifying, and / or collecting grass, leaves, dirt, or other materials generated during landscaping into a collection container is, in the exemplary embodiment, designed as a trailed mower and scarifier. This machine has a frame 1, which rests on the rear wheels 2 on the ground and on the drawbar 3 located at the front of the frame 1, which is coupled to a tractor (not shown). A mowing or scarifying unit 4 is arranged in a known manner at the front of the frame 1. This unit 4 is driven by the power take-off (PTO) shaft of the tractor via the driveshaft 5 in a known manner. Behind the mowing or scarifying unit 4, the collection container 6 is mounted on the frame by means of a lifting and tipping device 7. This lifting and tipping device 7 has a hydraulic cylinder 8 on each side of the collection container 6.

[0012] The collection container 6 is in its working position according to Fig. The upper part of the collection container 6 has a discharge opening 9. The discharge opening 9 is covered at its rear end 10 by the cover 11 and at its front end 12 by a cover plate 13. The cover plate 13 is pivotally attached to the collection container 5 at its front end by means of hinges 14. The cover 11 is pivotally attached at its rear end to the rear of the collection container 6 by means of hinges 15. The cover plate 13 and the cover 11 cover the discharge opening 9 when the collection container 6 is in its working position.

[0013] To empty the collection container 6 of the substances collected in it, the collection container 6 can be removed from the Fig. 1. Working position shown, via the hydraulic cylinders 8 of the lifting and tilting device 7 into the Fig. Lift and pivot the emptying position shown in section 2. This exposes the emptying opening 9, with the cover hood 11 and the cover plate 13 opening. The cover hood 11 also serves as a transfer flap, for example, if the material needs to be transferred without loss into a transport container (not shown).

[0014] The articulated joint 15, by means of which the cover 11 is attached to the collection container 6, is located between the upper rear region of the discharge opening 9 and the rear region of the cover 11. At least one spring element 16, designed as a gas spring or gas damper, is arranged between the collection container 6 and the cover 11. The spring element 16 is arranged such that, when the collection container 6 is moved from the discharge position to the working position, the spring element 16 decelerates the cover 11 during the closing process of the discharge opening 9. This ensures controlled pivoting of the cover 11 with a smooth and quiet closing of the discharge opening 9. The spring element 16 gently moves the cover 11 into its covering position when the collection container 6 is pivoted into the working position. Fig. 1 pivots so that the drain opening 9 is closed very quietly and in a controlled manner by the cover 11.

[0015] In the area of ​​the joint device 15, a spring-loaded stop element 17 is arranged, which acts between the collection container 6 and the cover 11. This spring-loaded stop element 17 determines the opening position of the cover 11 and limits the opening of the cover 11, as shown in the Fig. Figures 3-6 show this. Thus, the spring-loaded stop element 17 can additionally and gently decelerate the cover 11 in its final position during the final phase of the opening process. This gently establishes the final opening position for the cover 11 during the emptying of the collection container 6.

[0016] The spring element 16 is designed and arranged such that it does not actively assist the opening or closing of the discharge opening 9 by the cover 11. When the cover 11 pivots into the discharge position of the collection container and the cover 11 according to Fig. 2. The gas spring 16 does not assist in opening the cover; instead, the cover 11 reaches the illustrated open position due to its arrangement and weight. When the container 6 is empty and rotated back into the working position, as shown in Fig. As shown in 3-6, the cover is, if necessary, pressed towards the closing position by the spring-loaded stop element 17 and then pivots into its closed position in a braked manner due to its weight by the gas spring according to Fig. 1. Back. Because the cover slowly swings back into the closed position due to the gas spring 16, the cover 11 closes in a controlled, silent and gentle manner. The stop element 17 is designed as a compression spring.

[0017] Furthermore, the spring-loaded stop element 17 ensures, at the beginning of the closing process of the emptying opening 9 by the cover 11, that the collection container 9 and the cover 11 are in the Fig. The position of the collection container 6 and the cover 11 shown in Figures 3-6 ensures that the cover 11, even in an unfavorable position as shown in the aforementioned figure, moves towards the closing position immediately when the collection container is moved from the emptying position to the working position. Fig.1 is pressed. This is achieved gently by the fact that the spring-loaded stop element 17 rests against the cover 11 at the beginning of the closing process of the emptying opening 9 through the cover 11 and presses the cover 11 in the direction of the covering position of the cover 11.
