Description

The proposed utility model relates to hoisting and transport engineering and can be used in agricultural production for loading organic fertilizers, peat and other bulk materials into vehicles with a predominance of straw and large impurities.

Known working equipment of a single-bucket excavator containing a handle with a bucket having an upper wall pivotally connected to the handle using brackets, a bottom with a cutting knife on which teeth are mounted, side walls with cheeks [1].

This working equipment on the handle of the excavator is installed in the position of a backhoe or a direct shovel and is used in various operations for loading bulk cargo into vehicles. However, the possibilities of using this working equipment for loading organic fertilizers and other bulk materials into vehicles are limited due to low productivity.

Closest to the technical solution and the achieved result, the proposed utility model includes working equipment of a single-bucket excavator containing a handle with a widened bucket having an upper wall pivotally connected to the handle using brackets, a bottom with a cutting knife on which the teeth are mounted, side walls with cheeks , amplifiers installed to the outer surface of the bottom, made in the form of a pair of two arcs of circles with an internal touch, and the upper wall [2] - prototype.

Making the bucket wider increases its width and capacity, which leads to an increase in productivity when loading fertilizers, peat, sand and other bulk cargoes into vehicles.

The disadvantage of this device is that when loading semi-liquid organic fertilizers into vehicles, the capacity of the bucket is reduced due to sticking due to the excessive viscosity of the latter to its bottom. To clean the bucket, it is necessary to shake it with additional manipulations with the handle using the hydraulic cylinder, which takes a long time. This reduces the performance of the work performed.

The essence of the proposed utility model lies in the fact that the known working equipment of a single-bucket excavator containing a handle with a widened bucket having an upper wall pivotally connected to the handle using brackets, a bottom with a cutting knife on which teeth are mounted, side walls with cheeks, amplifiers mounted to the outer surface of the bottom, made in the form of a pair of two arcs of circles with an internal touch, and the upper wall, the surface of the bottom is made in the form of flexible interconnecting links.

As a result of the analysis of literary sources, no identical execution of the proposed device was found. Moreover, distinctive features from the prototype signs give the claimed combination of new properties, manifested in a positive effect.

When supplying the broadened bucket with a bottom made in the form of flexible interconnecting links, a reduction in the specific metal consumption of the product is achieved without a significant reduction in the rigidity of the structure. This ensures the technological process of filling the bucket only with straw and solid fractions of organic fertilizers necessary to increase the humus of the soil, and completely emptying the bucket without additional manipulation of the handle with the help of the hydraulic cylinder due to the shaking action of the flexible links of the bottom on the material. These circumstances lead to an increase in excavator productivity when loading semi-liquid organic fertilizers into vehicles with the predominance of straw and large fractions in them.

As a result, when the proposed device is operating, a positive effect is achieved that exceeds the effect of the prototype. A new set of features of the claimed device, providing a positive effect, has significant differences.

The figure shows a General view of the working equipment of a single bucket excavator.

The working equipment of a single-bucket excavator contains a handle (not shown in the diagram) with a widened bucket. The bucket is a welded structure consisting of a bottom 1 with a cutting knife 2, on which the teeth 3, upper 4 and side walls 5 with cheeks are installed 6. Moreover, the surface of the bottom 1, consisting of flexible connecting links 7, is made in the form of a pair of two arc of circles with an internal touch. To give rigidity to the broadened bucket, amplifiers (beams) are welded to the outer surface of the upper wall 4. The bottom 1 also has amplifiers (stiffeners) 9 on the outer surface side, on which flexible connecting links 7 are supported in the central part of the bucket cavity. To the upper wall 4 welded scarves 10 and brackets 11 for hanging on the handle of the excavator. The connecting dimensions are unified with the working body of the excavator. The working equipment can be installed on the handle of the excavator in the position of a forward and back shovel. Installation and dismantling of it is carried out by means of the fingers included in the excavator kit for connecting similar working bodies.

The technological process of working equipment shovel excavator is as follows.

For loading organic fertilizers, peat and other bulk materials into vehicles, the bucket of working equipment of a single-bucket excavator is hung on the handle in the position of a forward or backhoe. With the handle of an excavator, the bucket is lowered to the base of the bulk of semi-liquid organic fertilizers, then with the help of the handle, the bucket is moved to the upper position due to the hydraulic cylinders. When moving

the bucket with a knife 2 with teeth 3 cuts off the material and is filled with it, while excess water passes through the holes of the bottom 1, made in the form of flexible interconnected links 7. In the bucket cavity there remain straw and large fractions of organic fertilizers, which are transported and shipped further by the bucket to vehicle. When shipment of organic fertilizers complete emptying of the bucket without additional manipulation of the handle using the hydraulic cylinder is achieved due to the shaking action of the flexible links 7 of the bottom 1 on the material.

The advantage of the proposed utility model in comparison with the prototype is to reduce costs and increase productivity when loading semi-liquid organic fertilizers in vehicles. The use of this technical solution in the national economy provides an extension of the field of rational use of a bucket excavator.
