DE400926C - Self-discharger - Google Patents

Description

The invention relates to such self-dischargers, their unloading flap against an automatic return from the unloading position to the loading position by a locking device is secured and consists primarily in the fact that one for locking the discharge flap Locking pawl is provided that connects to the locking device for the discharge flap in the way that the pawl is in connection with a rotation of the locking shaft in the sense of unlocking the discharge flap can pass into the locking position and when this shaft rotates in the sense of Locking of the discharge flap is moved out of its locked position.

In the drawings, an embodiment of the invention is shown for simultaneous use Discharge to both sides set up self-discharger explained, namely shows

Fig. Ι a front view of the self-unloader in the loading position and

Fig. 2 the same view in the. Discharge position.

Furthermore, Fig. 3 shows on a larger scale a detail of Fig. 2 and

Fig. 4 is a section along 4-4 of Fig. 3, seen from the left.

The self-unloader has two unloading flaps B and C connected to the underframe A by links b \ δ ² or c ¹ , c ² , the insides of which are in an articulated connection with one another through a plate D. Two of the two end walls A ^{r of} the self-unloader

Initially lying links b ¹ and c ¹ are connected to the unloading flaps B and C by bolts R , one end of which is formed into a tooth e ¹ (see especially Fig. 3 and 4). With each tooth e ¹ is able to engage a f ¹ with ratchet teeth provided pawl F, which is swingably supported on the underframe A. The side walls G and H of the self-unloader are pivotably mounted at their upper edge on the end walls A ^χ rigidly connected to the VP underframe .4. They have hooks g ¹ and h ¹ on their lower edges , which in the loading position (Fig. 1) reach under the unloading flaps B and C and serve as supports. On that of the two end walls A ¹ , which is the bolt E , each provided with a tooth e ¹ , is a locking shaft / bearing two hand levers i ² mounted, which with two thumbs i ¹ provided at their ends, the side walls G and H in the Able to lock the loading position. Furthermore, two lever arms i ^s (see especially Fig. 4) are attached to the locking shaft /, at the free ends of which a rod * '* is articulated, each of which can grip under one of the pawls F with a hook i ⁵ .

In the loading position of the self-unloader, the side walls G, H and the unloading flaps B, C are fixed by the thumbs i ¹ reaching over the side walls G, H. The lever linkage P, * ⁴ , i ⁵ assume the position shown in Fig. 1 (cf. also the dot-dash position in Fig. 4), in which the pawls F of the hook i ^s out of engagement with the teeth e ^{l of} the bolts E to be held. If the self-discharging can be converted into the unloading position, the locking shaft / by means of a hand lever ^i%, by rotating the thumb i ¹ out of engagement with the side walls of G, H and brought this unlocked thereby. The side walls G, H and the bottom flaps B, C then swing into the position shown in Fig. 2 under the pressure of the cargo. When the side walls G and H are unlocked, the rods i ^{4 also} move downwards, thereby releasing the pawls F. The pawls then swing down under the action of their weight, so that the teeth e ^{1 of} the bolts E slide along the teeth f ^{1 of} the pawls F during the unloading movement of the flaps B and C. Now look for some kind of power, e.g. B. the weight of the cargo left lying on the plate D during unloading, the unloading flaps that have not completely passed into the unloading position or for any reason due to the loading position, the teeth e ¹ brace against the pawls F and thereby prevent an automatic swing back of the bottom flaps.

If the self-unloader is to be returned to the loading position, the locking shaft / is rotated in the sense of locking until the lever linkage i ³ , i ^l , i ⁵ lift the pawls F from the teeth e ^{1 of} the bolts E. The unloading flaps are then swung back into the loading position by hand or, depending on the arrangement of the flaps, automatically swing back into the latter and rest on the hooks g ¹ or h ^{1 of} the side walls G and H in the loading position. By turning the locking shaft further / in the sense of locking, the side walls G and H and thus also the unloading flaps B and C are locked again.

Claims (4)

Patent Claims: 1. Self-discharger, the discharge flap of which is secured against an automatic return from the discharge position to the loading position by a locking device, characterized in that a pawl (F) is provided for locking the discharge flap (B or C), which is connected to the locking device ( /, i ¹ ) for the discharge flap. (B or C) is connected in such a way that the pawl (F) can pass into the blocking position when the locking shaft (/) is rotated in the sense of unlocking the discharge flap (B or C) and when this shaft rotates (/) in the sense of locking the discharge flap (B or C) is moved out of its locked position. 2. Self-unloader according to claim 1 with unloading flaps forming a donkey's back in the unloading position, characterized in that the pawl (F) is rotatably mounted on the underframe (A) of the self-unloader and is able to engage with a ratchet tooth (e ¹ ) which is at a member (E) participating in the movement of the unloading flaps is arranged. 3. Self-unloader according to claim 1 and 2, characterized in that the member (E) carrying the ratchet tooth (e ^x ) forms the pivot pin of a discharge flap (B or C). 4. Self-unloader according to claim 1 and 2, characterized in that the pawl (F) is provided with several teeth (f ¹ ) on which the ratchet tooth (e ¹ ) slides along during the unloading movement of the flaps (B and C). 1 sheet of drawings.
