Description

[0001] The invention relates to an asparagus bed cutter according to the preamble of claim 1.

[0002] A generic asparagus bed cutter is known from DE 40 02 732 C2. This well-known asparagus bed cutter uses a gear drive to drive cutters. The housing of the asparagus bed cutter according to DE 40 02 732 C2 features lockable flaps that allow access to the interior of the machine when opened.

[0003] Another asparagus bed cutter is known, for example, from DE 20 2015 007 385 U1. This asparagus bed cutter has two cutter units, each comprising several cutter discs rotating around a common axis. The gearbox of the asparagus bed cutter according to DE 20 2015 007 385 is constructed in several parts, with one side of the gearbox housing being removable.

[0004] The invention is based on the object of providing an asparagus bed cutter which is further developed compared to the prior art and which has fully opening housing flaps for better maintenance and cleaning, whereby an additional benefit is sought compared to conventional solutions.

[0005] This object is achieved according to the invention by an asparagus bed cutter having the features of claim 1. The term "asparagus bed cutter" is used regardless of which plants are actually being cultivated in the individual case. The field of application is therefore not limited to asparagus cultivation.

[0006] The asparagus bed cutter is designed for attachment to a tractor or other suitable vehicle and, in a known basic design, comprises paired cutters, between which a space is formed for forming a soil dam. The rotation axes of the cutters are aligned in the longitudinal direction of the tractor or other vehicle. Each of the at least two cutters has at least one housing flap.

[0007] According to claim 1, a pivoting cleaning slide, commonly referred to as a scraper, is mounted in each of the housing flaps and serves to remove contaminants. The pivot axis of the cleaning slide runs parallel to the rotation axes of the milling device.

[0008] The cleaning slide in the housing flaps can encompass several strikers of the milling device and be U-shaped. The two U-shaped legs of the cleaning slide can be aligned parallel to two opposing side walls of the housing flap, while the U-shaped base of the cleaning slide touches an upper wall of the housing flap, at least in one possible position of the cleaning slide, to remove contaminants adhering to it. The two U-shaped legs of the cleaning slide can be spaced from the aforementioned side walls or can also touch these walls.

[0009] The cleaning slide can be pivoted around its pivot point by an actuator.

[0010] The actuator operates hydraulically or electromechanically, for example. The housing flaps, each assigned to a milling device, can be pivoted using paired hydraulic cylinders located above the housing flaps. This opens up the interior of the milling device and facilitates maintenance or repair of the beaters.

[0011] An optional first locking mechanism is available that blocks the cleaning slide when the housing cover is open, so that it rests in a parked position when the housing cover is open. A possible second locking mechanism prevents the housing cover from opening while internal components, such as the cleaning slide or the milling machine's striker, are still moving, to reduce the risk of injury. Both locking mechanisms can be designed, for example, as a purely mechanical system or as part of a hydraulic system.

[0012] The housing cover comprises, for example, a supporting plastic part and / or a steel component, in particular a sheet metal part, and can contain a rubber, stainless steel, Teflon, or other plastic insert, or even a textile insert, possibly covered by a smooth insert. Viewed in the longitudinal direction of the axes of the milling devices, the housing cover can, for example, have a rounded shape to match the diameter of the milling devices. Alternatively, a square shape of the housing cover is possible.

[0013] An embodiment of the invention is explained in more detail below with reference to a drawing. In the drawings: Fig. 1 an asparagus bed cutter in rear view with open housing flaps, Fig. 2 an asparagus bed cutter in rear view with closed housing flaps, Fig. 3 an asparagus bed cutter in side view with the housing flap open, Fig. 4 a housing flap in side view with cleaning slide in working position, Fig. 5 a housing flap in side view with cleaning slide in park position, Fig. 6 a housing flap in interior view with cleaning slide in park position.

[0014] An asparagus bed cutter, identified overall by reference number 1, comprises, as shown in Fig. 1 shows pairs of milling devices 2, between which a space DR is formed for forming a dam. Housing flaps 3 are attached to each of these milling devices 2 by means of hinges 11. The hinges 11 thus define the axes parallel to the rotation axes of the milling devices 2, about which the housing flaps 3 can be opened and closed.

[0015] Each housing flap 3 can be tilted from a closed position by at least 45° toward the top of the asparagus bed cutter 1 to provide a clear view into the interior 4 of the cutter device 2 and its beater 12. The housing flaps 3 are opened by paired hydraulic cylinders 6, which are attached on the one hand to the top of the asparagus bed cutter 1 and on the other hand to a suspension 8 of the housing flaps 3. The hydraulic cylinders 6 are part of a hydraulic system designated overall by 5.

[0016] At least one cleaning slide 9 is mounted in each of the housing flaps 3, which can be pivoted by at least 45° about a pivot point 10, i.e., in three-dimensional terms, about a pivot axis 10. The cleaning slide 9 is U-shaped and thus consists of two U-legs 13 aligned parallel to side walls 15 of the housing flap 3 and a U-base 14 connecting the U-legs 13 and aligned parallel to an upper wall 16 of the housing flap 3. The U-legs 13 and the U-base 14 are tangent to the side walls 15 and the upper wall 16 at least in one setting in order to remove any possible contaminants from them. The pivoting movement of the cleaning slide 9 is carried out along the upper wall 16 of the housing flap 3 and is aligned parallel to the rotation axes of the milling device 2.

[0017] Fig. 2 shows the entire asparagus bed cutter 1 with completely closed housing flaps 3. A first locking mechanism (not shown) prevents the housing flaps 3 from opening as long as components in the interior 4 of the cutter device 2, such as a cleaning slide 9 or a beater 12, are still moving.

[0018] In Fig. Figure 3 shows a side view of a milling device 2 of the asparagus bed cutter 1. The open housing cover 3 provides a view of the interior 4 and thus the beaters 12 of the milling device 2, facilitating maintenance, repair, and cleaning.

[0019] More detailed views of a housing flap 3 are shown with Fig. 4 and Fig. 5 given. In Fig. 4, the cleaning slide 9 is in a nearly vertical position, which describes a possible working position. From this position, the cleaning slide 9 pivots downwards about its pivot axis 10 along the upper wall 16 of the housing flap 3. The movement is carried out by means of an actuator 7 designed as a hydraulic cylinder. Fig. 5, the cleaning slide 9 is in an almost horizontal position after movement by the actuator 7, which simultaneously represents the parking position of the cleaning slide 9.

[0020] An optional lock (not shown) prevents movement of the cleaning slide 9 while the housing flap 3 is open.

[0021] In Fig. Figure 6 shows a housing flap 3 from the inside. Here, the cleaning slide 9 is back in its parked position. The U-shaped legs 13 are aligned almost horizontally.
