Wear-resistant inserts are made in the form of separate plates, respectively connected to the guide surface of the base wall, with the guide surface of the upper shelf and with the guide surface of the lower shelf, each insert on the connected guide surface is fixed by at least one connection "spline" and at least one threaded connection.

Description

The useful model belongs to mining engineering, can be used in niche-cutting complexes, cleaning combines.

A guide shoe for a roller-type harvester and wear-resistant inserts for guide shoes are known from the prior art, comprising at least one base wall that includes a guide projection, on the side of the base wall, for engagement under the rack drive of the rack drive mechanism, and which includes a guide surface for engagement by rail drive, while the guiding projection and the guiding surface are made on wear-resistant inserts, which are stationary with respect to the guide shoe and are attached in such a way that it is possible to carry out a replacement, and at the same time, the wear-resistant inserts are located in the receivers in such a way that they can be removed from the lower side (11.

The disadvantages of this guide shoe include the fact that the wear-resistant inserts proposed in it have a complex and bulky design.

The basis of the proposed technical solution is the task: to create a simpler design of replaceable wear-resistant inserts of the guide shoe.

As a result of solving the task, a technical result will be obtained, which consists in ensuring the ease of manufacture and ease of installation/disassembly of wear-resistant inserts. Achieving a technical result will provide consumer properties: increased repairability of the guide shoe, the possibility of using remfond with minimal design modifications.

In the already known guide shoe, which contains at least a base wall (1), an upper shelf (2) and a lower shelf (3), the guide surfaces (1a, 2a, Za) of which are covered by replaceable wear-resistant inserts, according to the technical solution, wear-resistant inserts are offered perform in the form of separate plates (6, 8, 9) respectively connected to the guide surface (Ta) of the base wall (1), to the guide surface (2a) of the upper shelf (2) and to the guide surface (Za) of the lower shelf (3), at the same time, fix each insert with at least one "spike-groove" connection (4) and at least one threaded connection (10).

In addition, it is suggested: - fixing the plate (8) on the guide surface (1a) of the base wall (1) and the plate (b) on the guide surface (2a) of the upper shelf (2) with at least one threaded connection (10) with

From the side of the plates themselves, and fix the plate (9) on the guide surface (Za) of the lower shelf (3) from the side of the lower shelf (3); - additionally fix the plate (b) of the upper shelf (2) relative to the plate (8) of the base wall (1) with a key (7).

The causal relationship between the newly introduced essential features of the formula and the technical solution that is claimed is explained as follows.

The proposed guide shoe is optimal in design for niche-cutting complexes that work on small cutting lengths, about meters. Wear-resistant inserts in the form of separate plates are easy and inexpensive to manufacture from wear-resistant material, and the "spike-groove" connection and threaded connection will provide convenience and ease of installation/disassembly of wear-resistant inserts.

Thus, a new set of essential features allows to achieve the declared technical result: ensuring ease of manufacture and ease of installation/disassembly of wear-resistant inserts, and ensuring consumer properties: improving the repairability of the guide shoe, the possibility of using remfond with minimal design modifications.

The technical solution is explained by an example, the implementation of which is not the only possible one, but clearly demonstrates the possibility of achieving the stated technical result with the proposed new set of essential features.

The essence of the technical solution is represented by the drawings, which show: fig. 1 - slotted complex (side view) with guide beam (5) and guide shoe; fig. 2 - a direct view of the guide shoe with a local cut along the fixing node of the key (7) additionally introduced into the structure; fig. C - a side view of the guide shoe fig. 2 with a local cut through the threaded connection of fixing plate (8) on the guide surface (1a) of the base wall (1), plate (6) on the guide surface (2a) of the upper shelf (2) and plate (9) on the guide surface ( Behind) the lower shelf (3); fig. 4 - local section of fig. 2 on the "spike-groove" connection (4) for each of the plates (6, 8, 9); fig. 5 - a section of the fixation node of Fig. 2 on the key (7) additionally introduced into the structure. 1 - base wall; 2 - upper shelf;

C - lower shelf; because 1a is a guiding surface;

2a - guiding surface;

Za - guiding surface; 4 - "spike-groove" connection; - guide beam; 5 6 - plate; 7 - key; 8 - plate; 9 - plate; - threaded connection. 10 The implementation of the technical solution is shown in examples (Fig. 1-5).

The claimed guide shoe is used in a niche-cutting complex and is optimal for this type of machine, although it can also be used for cleaning combines.

The guide shoe includes at least a base wall (1), an upper shelf (2) and a lower shelf (3). The guide surface (Ta) of the base wall (1), the guide surface (2a) of the upper shelf (2) and the guide surface (Za) of the lower shelf (3) are closed by replaceable wear-resistant inserts, which are proposed to be made in the form of separate plates (6, 8, 9) ) respectively connected to the guide surface (Ta) of the base wall (1), to the guide surface (2a) of the upper shelf (2), and to the guide surface (Za) of the lower shelf (3). Immobility of the first relative to the second is provided by at least one "spike-groove" connection (4) and at least one threaded connection (10) for each pair. The "spike-groove" connection (4) in the example is made with a pin.

For ease of assembly/disassembly, the fixing of the plate (8) on the guiding surface (Та) of the base wall (1) and the plate (6) on the guiding surface (2a) of the upper shelf (2) with threaded connections (10) is carried out from the side of the plates themselves, and fixing the plate (9) on the guide surface (Za) of the lower shelf (3) is carried out from the side of the lower shelf (3). The specific number of threaded connections (10) for fixing each plate (6, 8, 9) is selected constructively depending on the working conditions and the length of the guide shoe.

Plates are replaced as follows. The frame of the slot-cutting machine together with the guide shoe is lifted from the guide beam (5) upwards, the guide shoe is disconnected and the plates are replaced. Pins are installed in plates (b, 8, 9), then one at a time

From the plate (b) is connected by the "spike-groove" connection (4) on the guide surface (2a) of the upper shelf (2), the plate (9) is connected by the "spike-groove" connection (4) on the guide surface ( Behind) the lower shelf (3), after that, connect the plate (8) with a "spike-groove" connection (4) on the guide surface (1a) of the base wall (1). Then fix each plate (6, 8, 9) with at least one threaded connection (10). In the example of threaded connections, there are several for each plate (6, 8, 9). The number and diameter is determined depending on the working conditions and the length of the guide shoe.

The plate (6) of the upper shelf (2) is additionally recommended to be fixed relative to the plate (8) of the base wall (1) with a key (7) for the reliability of the attachment.

For a person skilled in the art, the preceding description suggests some modifications of the guide shoe that fall within the protection of the appended claims of the utility model formula.
