Description

The invention relates to mechanical engineering, namely to bucket loaders, in particular to loader buckets.

In winter, one of the main problems in maintaining roads, sidewalks and squares is snow removal. Significant material and time resources are spent on ensuring the operational characteristics of snowy territories. This is due both to natural and climatic factors (the intensity and duration of snowfall, the effect of winds and ambient temperature and, as a consequence, the formation of ice on the roads), and to organizational factors leading to irregular work. The impact of these factors contributes to the formation of snow.

For snow removal from roads, sidewalks, and squares, city services use plow vehicles based on tractors and automobiles; rotor and milling rotor machines. Due to the versatility and manufacturability of the work in the maintenance of roads, wheel loaders are widely used.

В таком случае ковш погрузчика также находится под углом к горизонту. Это приводит к тому, что убрать снег в один проход снегопогрузчиком затруднительно, также происходит износ одной стороны А ножа ковша (Фиг. 1), которая находится у основания угла крена машины к автомобильной дороге.Snow removal by a front-end loader from a highway in the event of snowfall is shown in FIG. 1. When cleaning the snow coast (Fig. 1) with a loader, one side of the machine that moves along the coast is higher, and the other, which moves along the surface of the road without snow, is lower. The result is a roll angle of the machine

In this case, the loader bucket is also at an angle to the horizon. This leads to the fact that it is difficult to remove snow in one pass with a snow loader, and there is wear on one side A of the bucket knife (Fig. 1), which is located at the base of the roll angle of the machine to the road.

To solve this problem of uneven contact of the loader bucket with the surface being cleaned, a bucket for the front-end loader with the possibility of skew is proposed.

Known reclamation scraper-scheduler with a movable damper blade [RF Patent No: 113282, IPC E02F 3/64, publ. 02/10/2012]. The reclamation scraper-planner consists of: a coupling device, a traction frame with a blade mounted on it with side walls, a rear frame on pneumatic wheels, hydraulic cylinders for controlling the rear frame, a shutter-blade constructed structurally moving along the carriages along the guide beams of the longitudinal traction frame, thanks to what is the shift of the accumulated prism of soil dragging to the rear of the bucket with a dump blade, not along a parabolic trajectory, but combining the kinematics of the blade shutter along the longitudinal o-parabolic trajectory, thereby contributing to a decrease in resistance when it is introduced into the prism of drawing and subsequent pushing of the soil.

The disadvantages of this device are: the device is not intended for snow removal, there is no way to independently load snow into the dump truck body, there is no possibility of skewing at the dump.

It is known the invention of the working equipment of a machine for snow removal in urban conditions [RF Patent No. 109762, IPC E01H5, publ. 10.27.2011], consisting of a self-propelled tracked or wheeled vehicle with a linkage system and a frontal bucket, characterized in that the linkage system is made in the form of a plate, to which a manipulator is pivotally connected, consisting of a rear beam with a lifting cylinder and a front beam with a scooping cylinder , which, in turn, are pivotally interconnected by two rods, forming a parallelogram as a whole, providing horizontal movement of the front crosshead using a lateral displacement hydraulic cylinder I, pivotally connected to the side unloading bucket, while the working equipment plate is rigidly attached to the front or rear of the chassis frame of the base machine.

The disadvantages of this device are the large dimensions of the structure, there is no way to clean the snow in the yards, there is no way to remove compacted snow, high financial costs of production.

In the invention of a snowplow [RF Patent No. 100526, IPC E01H 6/00 (2006.01), publ. 12/20/2010], which contains the base chassis of a front-end loader, a mechanism for fastening and controlling removable equipment, as well as a mounted snow loading bucket formed by the upper, lower, rear and side walls, a knife and eyelets of fastening to the control mechanism of the base front-end loader, characterized in that the bucket is made with a front gate wall-cover installed with the possibility of movement in the skids made in the side walls of the bucket with the help of a gear drive driven by those placed on the upper wall the bucket of two hydraulic motors, and with a pair of opposed sealing pistons located in the initial position at the side walls of the bucket, each of which is connected via flat rods to the rods of a pair of drive hydraulic cylinders located in the cavities of the upper and lower walls of the bucket, and the cylinder rods are oriented to the center of the bucket .

The disadvantage of this invention is the inability to rotate the bucket in a horizontal plane, there is no possibility of removing snow from the roads, it is intended only for loading snow, a complex structure.

The most similar invention is the invention: Hydraulic blade dozer blade [Patent SU 1157181 A, E02F 9/22, publ. 05/23/1985], which has control cylinders pivotally connected to the blade, an electrohydroshaker with its electric control system, characterized in that, in order to reduce digging resistance when using a bulldozer with a blade swash cylinder, it is equipped with a governing body electrically connected to the electrohydroshaft electrocontrol system, which has vibrocontacts, a rod rigidly fixed to the skew cylinder, mounted on the last momentary electrical switch and time relay with asymmetric cyclogram work, which is associated with vibrokontaktami.

The disadvantages of this invention are the complex design, the design is not intended for snow removal, the presence of two to four pairs of additional drive cylinders, the increased volume of the hydraulic system.

The objective of this technical solution is to increase the productivity of the front-end loader (for example, Mustang 3300V, Bobcat S530MКCM 800, etc.) when cleaning snow, as it allows you to clean the road surface in fewer passes, as it allows to reduce uneven wear on the worker body (bucket) at point A when hitting a snow coast (Fig. 1). When using a bucket for a front-end loader with the possibility of skewing, the loader still has the opportunity to independently load snow into vehicles (for example, a dump truck).

The technical result of the proposed design of the loader bucket when hitting one side of the machine on a snow roll is the possibility of skewing the bucket, with the aim of aligning it in parallel with the surface cleared of snow. The skew is carried out using two skew cylinders and a swivel, which allows you to rotate the bucket at an angle γ (Fig. 2).

The specified technical result is achieved in that the bucket for the front loader with the possibility of skewing is able to skew the bucket in the frontal plane (Fig. 3). A hinge is installed between the mounting plate and the bucket, as well as two hydraulic cylinders for controlling the skew of the bucket. Accordingly, the hydraulic circuit of the modernized front-end loader is modernized by two executive hydraulic motors (skew cylinders) and a control valve of the skew of the front-end loader bucket.

The invention is illustrated by drawings, where in FIG. 1 shows a loader with a standard bucket, without the possibility of skewing; in FIG. 2 shows a loader with a bucket for a front-end loader with the possibility of skew (dashed lines in the front view show the skew of the working body); in FIG. 3 shows a bucket for a front-end loader with the possibility of bias (in three types).

The bucket for the front loader with the possibility of skewing consists of a bracket 1, fixing clips 2 for fixing to standard fasteners for attachments of the loader, bolt connections 3 that fix the mounting plate 6 to the mounting plate 8. The bucket 4 has a U-shaped bracket 5, which is connected to mounting plate 6. The mounting plate 6 is connected to the mounting plate 10 using a sleeve 7 and a finger 9. On both sides at the same distance from the Central axis of the bucket are the skew cylinders 11 (you can use one hydrocylin skew core 11) connecting the bucket 4 and the mounting plate 8.

The device operates as follows when removing snow from roads, squares and sidewalks and moving it to the place of loading. In FIG. 3, the front view shows the skew of the bucket, the skew is performed using two skew cylinders 11 and a swivel, the swivel consists of a sleeve 7 and a pin 9. The adjustment of the skew angle of the bucket can be done either manually by the operator or in automatic mode. In automatic mode, the deviation of the machine from the horizontal position is monitored by any generally known methods and the signal is sent to the distributor and to the skew cylinders 11. This modernization eliminates wear of the lower corner parts of the bucket, since the working body withstands the horizon relative to the surface being cleaned of snow.

The use of this skewed bucket allows snow removal in fewer passes of equipment, as the area of contact between the bucket and the roadway increases. Also, this modernization eliminates the wear of the working body (bucket) when hitting a snow coast.
