Transport trolley.

The invention relates to a transport trolley with a receiving device, which slides the picked harvest material onto the bottom plate of a transport channel / in which the teeth of a rotating transport device periodically engage and that harvest material, if necessary after reduction, by knives arranged in the transport channel transport into the cargo space.

In the known transport wagons of this type, it has hitherto been considered that blunt damage to the harvested material by squeezing action when the teeth are retracted and by avoiding compaction to the bottom plate, which damages green fodder, for example a reduction in quality and cause decay.

For example, it is known from DE-PS 1 163 072 to avoid pinching the harvested material during stripping by a scraper wall arranged opposite the bottom plate, through which the teeth withdraw from the transport channel, because the intersection of the transport teeth with the slotted inner wall of the transport channel at the edges of the teeth facing the direction of movement in the direction of movement and the tangents tangent to the slotted wall enclose an angle which is equal to or greater than 90 ° at each location of the scraper wall. This was accomplished by backwardly sloping leading edges of the transport teeth. However, the backward inclination may not be so great that the transport teeth with the bottom plate on the other hand enclose such a small angle that the harvested material is wedged in between and pinched.

The material treated in this manner and treated in a slightly compacted manner, of course, requires more loading space than material that is more compacted. Therefore, in order to limit the frequent journeys between field and farm for the introduction of the harvested material, it was usually necessary to rely on large cargo space capacities and therefore on large and heavy transport trucks.

The object of the invention is therefore to provide a transport trolley with which one can load harvested materials, which are already subjected to a compaction, such as harvesting materials intended for silage, with greater compaction and, optionally, other harvested materials, so that on the one hand, it is also possible to use lighter transport wagons and, on the other hand, to pre-press harvested materials for further compaction.

This object according to the invention is achieved in that a smooth first base plate and a second base plate in the circumferential direction of the teeth of longitudinal grooves approximately corresponding to the width of the teeth and partially receiving these teeth can be arranged alternately turn into.

In this way, the transport vehicles obtains further functions, which on the one hand increase the loading capacity and, on the other hand, by subsequent compaction or by structural change of, for example, silage harvested materials or of straw materials intended for spreading or incorporating into the soil, the subsequent processing operations. facilitate and optimize storage and compaction or soaking into the soil.

Further elaborations according to the invention are stated in the subclaims 1 to 10? the embodiment according to subclause 8 and following is generally applicable to transport trolleys.

The invention is explained below with reference to the schematic drawing on the basis of an exemplary embodiment.

Pig. 1 is a cross-sectional view of the front part of a transport cart and its loading device; Fig. 2 is a top view of the loading device; and Fig. 3 shows the transport trolley according to Fig. 1 in a different setting.

Fig. 1 shows the front part of a transport trolley with a transport device 1, a receiving drum 3 arranged in front of said transport trolley on a bottom plate 2 thereof and a scraper base 4 arranged behind it. The transport device 1 consists of a central unit. % »- * -Λ • ·, ·“ y) «z 3 axle 5 on the two side shields 6, of which each outer tine 8a and control member 8b respectively of the tine shafts 7 and attached tines 8 are mounted in rotary hinges 6a.

The reference numeral 9 denotes a drum which is rotatably mounted with 5 stubs 10 and which is rotatably mounted on the central tube, to which the teeth extend through slots 11.

Numeral 12 indicates a scraper plate, which leans against the bottom of the drum, which scraper plate is connected to the top wall 13 of the loading space (fig. 2). As can be seen from Fig. 1, slots 14 are provided in the front sides 9a of the drum 9, through which fixing screws 15 are inserted, which are screwed into thin shields provided on the side shields 6. According to the invention, by engaging the screws 15 and displacing the drum 9 relative to the side shields 6, the engagement angle of the teeth 8 with respect to the bottom plate 2 and the ribbed plate 22, which according to the invention can be placed on the bottom 2 and, if desired, can be slid into side rails 16a and can be fastened by quick fasteners 16b. When working with the ribbed plate 22, in whose grooves 23 the tips of the teeth 8 are fitted and intermittently engage in their circular movement, they enclose an angle at their front edges with the bottom thereof, which is smaller than 90 as much as possible ° should be to ensure that a strong press action is achieved. When working without the corrugated plate 22, the tines 8 are oriented more radially and at their front edges must enclose an angle of approximately 90 ° with the bottom plate 2, so that the harvested material is transported upwards without pressing to the bottom plate 2 as illustrated in Fig. 3.

The transport trolley proposed according to the invention can be universally used by this device. The material to be pressed simultaneously with the transport is not only compacted in the grooves 23 of the bottom plate 22, but at the same time also on the flanks of the. ribs 24 are cut off largely shearingly and thus reduced at the same time, which favors the compaction of the material.

If it is desired to spare the knives 25, it is of course possible to pivot the knives away from the conveying path, as well as to achieve a further reduction of the harvested material with those knives on the other hand and thereby a processing which leads to an in the silos particularly tightly packed storage, which accelerates the initiation of the lactic fermentation in the silo.
