Description

1 TARIFF PRODUCT HOLDER CLAW AND TRANSITION SLOT FOR BALING MACHINE. REGULATION TECHNICAL FIELD The invention describes the reverse movement of compressed plant material in piston-type balers. It relates to product-holding claw (hay dog) devices used for restricting movement. The invention specifically concerns a spring-loaded system that moves through a passage slot in the bale chamber wall. between the root / transition lateral surface area of ​​the product retaining tab and the opposite edge of the slot It relates to geometric arrangement. STATE OF THE ART In piston-type balers, the compressed plant material moves backward along the piston. to limit expansion during transport, on one or more walls of the bale chamber Product retaining tabs are used. In known systems, the product retaining tab is located on the outside of the bale chamber wall. It rotates around its pivot axis and is drawn into the bale chamber by a spring element. It is guided. The advancing plant material makes contact with the product-deflection surface, pushing the nail outwards. It pushes the material into position; after the material passes through, the spring element returns the claw to the product-holding position. During this movement, the root / transition lateral surface region of the nail moves opposite the transition slot. It follows a trajectory close to the edge. This is where plant material, dust, or similar particles come from. if it accumulates in the area, especially between opposing surfaces in the final return phase A wedge effect can occur, making it difficult for the nail to fully grow back. Therefore, the jamming in question depends not only on the slot width but also on the spacing between the tab and the slot edge. It also depends on the local geometry of motion between them. THE PURPOSE OF THE INVENTION The purpose of the invention is to enable the product-holding claw to return from its external position to its product-holding position. during which a narrowing occurs between the root / transition lateral surface region and the opposite edge of the transition slot. The aim is to reduce the tendency for compression interface formation. For this purpose, a local relief transition is created in the root / transition zone where the nail moves within the slot. the surface; and on the slot edge facing this surface, according to the terminal return geometry. A regulated border crossing has been established. 2 A BRIEF DESCRIPTION OF THE INVENTION In the root / transition lateral surface area where the product retaining tab moves within the transition slot, a local recess from the opposite slot edge relative to the continuation of the adjacent lateral surface profile. It has a relief transition surface. A counter-transition boundary exists in the opposite slot edge region facing the relief transition surface. These two areas are at least partially adjacent along the thickness of the bale chamber wall. They are positioned to correspond to each other. The counter-transition limit in the reference plane perpendicular to the pivot axis is the product- relief transition surface along the terminal return range ending at the holding position It remains outside the region it sweeps around the pivot axis and returns to that region in the direction of return. It follows a profile that does not converge correctly. This geometry narrows between the quotation mark and the slot edge during terminal return. the tendency for a wedge zone to form and the plant material in this region to retract the nail. It reduces the risk of making the return difficult. DESCRIPTION OF THE FIGURES Figure 1 shows the general layout of the product-holding claw arrangement on the bale hopper. It shows.

D - Thickness direction of the bale chamber wall DETAILED DESCRIPTION OF THE INVENTION The invention involves a device that loads plant material into a bale chamber (10) by a piston. It is applied in piston type balers in which the bale is compressed. The bale hopper (10) must be at least on one of its walls (11), the product holding tab (20) allows it to enter and exit the bale hopper. There is one passage slot (12). Product retaining claw (20), pivot axis (21) on the outside of bale chamber wall (11) It is attached in such a way that it can rotate around. The nail extends into the bale container of product- externally pushed outwards at least partially by the plant material advancing with the holding position It moves between locations. The spring element (22) forces the product-holding claw (20) towards the product-holding position. Spring The element could be a torsion spring, for example, working around the pivot axis (21). Product-deflection surface (23), pivot of the nail when it comes into contact with advancing plant material. It allows it to rotate to the external position around its axis (21). Product-holding surface (24), nail bale It restricts the backflow of compressed material when it returns to its chamber. A root / transition in the part of the product retaining tab (20) that moves within the transition slot (12). The lateral surface region (25) is located. At least part of this region has a local relief transition surface. (26) has been created. Relief transition surface (26) hypothetical continuation of the adjacent root / transition lateral surface profile. It has been retracted from the opposite slot edge. Thus, the local retraction covers the entire claw. Instead, it is created in the root / transition zone that interacts with the slot. opposite slot edge region on the side of the transition slot (12) facing the relief transition surface (26) (30) is located. At least part of this region forms the crossing border (31). 4 Relief transition surface (26) and counter-transition boundary (31), thickness of bale chamber wall (11) They are mutually positioned, at least partially, within the same interaction zone. The product retaining tab (20) transitions from the outer position to the product-holding position during relief transition. The surface (26) scans a region around the pivot axis (21). The boundary shown as 40 in Figure 4, not a physical part, but the relief transition surface scanned during terminal return. It is the outer boundary of the region. The terminal return interval is the critical transition boundary (31) of the relief transition surface (26). From the position where it enters the mutual working zone to the product-holding position of the nail It is the phase of movement that ends at the location it reaches. Counter-transition limit (31) in the reference plane perpendicular to the pivot axis (21), terminal return It remains outside the area scanned by the relief transition surface (26) throughout the interval and return It follows a profile that does not converge towards this region in that direction. With this arrangement, the interface between the relief transition surface (26) and the counter-transition boundary (31) The tendency for the terminal to transform into a tapering wedge shape during a return trip is reduced. Thus The plant material in this area makes it difficult to return the product-holding nail (20). The risk is reduced. Relief transition surface (26) provides a continuous transition to the adjacent root / transition lateral surface region (25). It can be connected by a transition. The opposite transition boundary (31) is also connected to the adjacent edge region of the transition slot (12). It can be connected via a seamless transition. In one application, the relief transition surface (26) is only in the root / transition lateral surface region (25) This is done while preserving the main lateral surface profile of the nail outside this area. In another application, on each of the two opposing root / transition lateral surfaces of the nail (20) a relief transition surface (26), each of the opposite edge regions of the transition slot (12) facing them In one of them there is a crossing point (31). Dimensions and local profiles of the relief transition surface (26) and the counter-transition boundary (31); pivot location, slot dimensions, bale chamber wall structure and claw movement geometry This can be determined accordingly. The adjustment depends on a specific angle or a fixed aperture value. It is not. The arrangement allows for a smooth transition via the product retaining tab without requiring an additional element. This can be implemented through the reciprocal geometry of the slot. METHOD OF APPLICATION TO INDUSTRY The subject of the invention is a modification of the bale chamber wall and product of piston-type balers. It can be applied in the manufacture of retaining nail components. Relief transition surface (26) is the product holding claw (20), and counter-transition limit (31) is the bale. The transition slot (12) in the wall of the reservoir (11) can be included in the manufacturing geometry. Under suitable structural conditions, the arrangement includes new balers as well as existing ones. by changing the geometry of the product holding claw and counterslot in machine designs applicable.
