Description

The proposed utility model relates to hoisting and transport machinery and can be used in agricultural production for the formation and mandrels of stacks of organic fertilizers, as well as for loading organic fertilizers, peat, sand and other bulk materials into vehicles.

Known working equipment odnokovshovogo excavator containing a handle with a bucket having an upper wall, pivotally connected to the handle using brackets, the bottom with a cutting knife on which the teeth are installed, side walls with cheeks / 1 /.

This working equipment on the handle of the excavator is installed in the position of a direct or backhoe and is used in various operations for loading bulk cargo into vehicles, forming and mandrels of organic fertilizer piles. However, the known working equipment has 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, the bottom of which is made in the form of a pair of two circular arcs with an internal touch , a knife with teeth attached to the bottom, side walls with cheeks, amplifiers mounted to the outer surface of the bottom and upper wall, and in the scoop cavity to the bottom and side walls / 2 / - prototype.

When the bucket is broadened, its grip width and capacity increase, which leads to an increase in productivity during the formation and setting of stacks of organic fertilizers, and

also when loading fertilizers, peat, sand and other bulk cargoes into vehicles. However, when conducting work, a pile of packed fertilizers, sand, and in winter, the layer of the frozen surface peel of the peat stack is poorly destroyed and the bucket cavity is not filled with completely scooped material. This reduces the productivity of the excavator with this work equipment.

The essence of the proposed utility model is 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, the bottom, the surface of which is made in the form of a pair of two arcs of circles with an internal touch, a knife with teeth, mounted to the bottom, side walls with cheeks, amplifiers mounted to the outer surface of the bottom and upper wall, and in the scoop cavity - to the bottom and side walls, in the middle part A knife-type amplifier is installed in the scoop cavity of the bucket, the cutting surface of which is made in a logarithmic spiral.

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 installing a knife-type amplifier in the middle part of the scooping cavity of the bucket, a more rigid structure is achieved without an excessive increase in the thickness of the bottom, upper and side walls, causing a decrease in the specific metal consumption of the product.

In addition, the use of a knife-type amplifier in the middle of the scooping bucket cavity allows you to intensively destroy and crush the layer of the frozen surface peat of the peat stack, or caked mineral fertilizers, or frozen piles of sand

etc., which determines the technological process of filling the bucket close to one hundred percent and its complete unloading. As a result of this, the productivity of an excavator with this working equipment is improved during various operations.

Further, the use of a knife-type amplifier, the cutting surface of which is made along a logarithmic spiral, causes the least resistance to digging material in relation to the direction of movement of the bucket.

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 schematic diagram 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, top 4 and side walls 5 are mounted with cheeks 6. Moreover, the surface of the bottom 1 is made in the form of a pair of two circular arcs with an internal touch. To give rigidity to the broadened bucket to the outer surface of the bottom 1 and upper wall 4, as well as in the scoop cavity to the bottom 1 and side walls 5, amplifiers 7, 8 and 9 are welded, respectively. To the upper wall 4 are welded scarves 10 and brackets 11 for hanging on the handle of the excavator. An amplifier 12 of knife type is installed in the middle part of the scooping cavity of the bucket, the cutting surface of which is made in a logarithmic spiral. The connecting dimensions are unified with the working body (backhoe) of the excavator. Work equipment can be mounted on the handle of the excavator in the position of a forward and back shovel. Installation and dismantling 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.

When forming and setting the stack of organic fertilizers, the bucket of working equipment of a single-bucket excavator is hung on the handle in the position of a straight shovel. With the handle of an excavator, the bucket is lowered to the base of the bulk of organic fertilizers, then by increasing the length of the handle due to the hydraulic cylinders, the bucket is moved to the upper position. When moving the bucket with a knife 2 and a knife-type amplifier 12 cuts off the material, completely fills it and moves it upward, simultaneously making a shipment. The stack is formed and set according to the annular movement of the excavator around the bulk of organic fertilizers with the given parameters in width, height and length.

The equipment can also be used for loading organic and mineral fertilizers, peat, sand and other bulk materials into vehicles. In this case, it is advisable to set the bucket in the position of a backhoe, and when it is introduced into a pile of packed fertilizers, sand or a frozen peat pile, the scooped material is cut with a knife 2 and intensively crumble with a knife-type amplifier 12, which causes the bucket to fill completely. Such a technological process of filling the bucket allows further complete unloading of material.

The advantage of the proposed utility model in comparison with the prototype is to increase productivity and, accordingly, reduce costs when forming and setting up stacks of organic fertilizers, when loading various bulk cargoes into vehicles.
