Description
[0001] Technical field
[0002] The device belongs to the field of mechanical engineering and is used for loading and unloading operations.
[0003] Prior art, analogues
[0004] The following types of material handling devices are known for loading loader buckets: those mounted above the cab on a lever, and those mounted on levers attached to the side surfaces. When working in confined spaces, the levers mounted above the cab and to the side surfaces of the bucket can easily be damaged, rendering the device unusable. Various grapples are also known, but their use in various applications is limited by their design.
[0005] The purpose achieved by this device
[0006] The purpose of the proposed device is to expand the types of work of the loader.
[0007] One of the main features of this device is its compactness in the stowed position. It does not protrude beyond the sides and bottom of the bucket, and folds into a recess on the rear wall of the bucket. This protects the levers from accidental damage when working in cramped conditions and allows for use in a variety of applications without restricting the driver's view from the cabin.

[0024] Disclosure, essence, advantages
[0025] 1. The device is made in the following form: Fig. 1-8 (sheets 3.1, 3.2, 3.3). On the rear wall of the bucket 1, on the outer side at the top, the lever 3 is pivotally attached, which is designed so that its shape copies and is slightly smaller than the longitudinal vertical recess 2 in the bucket 1, protruding inside this bucket 1 and by means of a hydraulic cylinder through additional blocks of levers and rods or through the gearbox of the hydraulic motor 8 rotates on a hinge joint in the vertical plane. To the opposite end of the lever 3, on a hinge joint 6, an additional lever 4, made of quadrangular profiles of different cross-sections, is fixed with the ability of the part of the smaller cross-section to move in the parts of the larger cross-section by means of a hydraulic cylinder fixed inside these parts. The lever 3 rotates on a hinge joint 6 in the vertical plane by means of a hydraulic cylinder 5.
[0026] Depending on the design of the loader, two levers may be fixed on the rear wall of the bucket and these two levers may be shifted towards each other (Fig. 3) and connected to each other by a jumper, be doubled, i.e. turned into one lever, and also articulated levers 3 and 4 may be doubled, i.e. with U-shaped forms (Fig. 5) and will be fixed in the middle on the rear wall of the bucket.
[0027] A shovel 9 is attached to the ends of the extending portion of lever 4. Shovel 9 is easily removable and wide, and its design varies depending on the type of material being moved and the conditions of use. The shovel may have a rubber strip at the bottom to prevent damage to the surface (asphalt, paving slabs) when moving snow, debris, leaves, etc. into the bucket, or it may have a serrated, pointed bottom for moving hard soil or compacted sand, crushed stone, broken brick, reinforced concrete block parts, icy materials, etc. into the bucket. Brushes, hooks, forks, and other structures and mechanisms may also be attached.
[0028] In the stowed position, articulated levers 3 and 4 fold into recess 2 on the rear wall of bucket 1, not protruding below the bucket floor. An additional hydraulic distributor with electromagnetic valves for lever operation can be installed on the rear wall of the bucket, along with two hoses for oil supply and discharge and an electrical cable. The control panel can be mounted anywhere in the driver's cab.
[0029] For a clearer understanding, the images on the figures are made as simple as possible.
[0030] 2. The device works as follows.
[0031] The bucket is lowered to the ground surface. Shovel 9, mounted on levers 3 and 4 at hinge joint 6, moves from behind the bucket via a hydraulic drive and is positioned on the surface in front of the bucket at a distance equal to the length of levers 3 and 4 with the extending part. Subsequently, moving toward the bucket via the hydraulic drive, it transfers materials into the bucket. The driver controls the levers from the control panel in the cab.
[0032] 3. This device is convenient for municipal services: in summer for various tasks, in autumn when there are heavy leaves, in winter when there is heavy snow, in spring when there are large piles of debris after winter, and in other situations. This device significantly compacts materials in the bucket by almost half, thereby doubling the productivity of bucket loaders. This device can also transport various structures, boxes, large-sized loads, and much more in the bucket, supporting them with levers from above. This device is also convenient for use in agriculture, construction, enterprises with a lot of bulk cargo, and many other applications.
[0033] Implementation
[0034] 1. The device is designed as follows: Fig. 1-8 (sheets 3.1, 3.2, 3.3). A lever 3 is pivotally attached to the rear wall of the bucket 1 on the outer side at the top. The lever is designed so that its shape copies and is slightly smaller than the longitudinal vertical recess 2 in the bucket 1, protruding inside this bucket 1 and, by means of a hydraulic cylinder through additional blocks of levers and rods or through a gearbox by a hydraulic motor 8, it rotates on a hinge joint in a vertical plane.
[0035] Attached to the opposite end of lever 3 via pivot joint 6 is an additional lever 4, made of rectangular sections of varying cross-sections. The smaller cross-section section can be moved within the larger cross-section section by means of hydraulic cylinders mounted within these sections. Lever 4 rotates vertically on pivot joint 6 via hydraulic cylinder 5.
[0036] Depending on the design of the loader, two levers 3 can be installed on the bucket and moved towards each other and connected to each other by a jumper (Fig. 3), i.e. turned into one lever, be doubled, or on the loader, the articulated levers 3 and 4 can also be doubled (Fig. 5 and Fig. 7) and will be fixed in the middle on the rear wall of the bucket.
[0037] A shovel 9 is attached to the end of the extending portion of lever 4. This shovel is easily removable and made of steel, and its design varies depending on the type of material being moved and the conditions of use. The shovel may have a rubber strip at the bottom to prevent damage to the surface (asphalt, paving slabs) when moving snow, debris, leaves, etc. into the bucket, or it may have a serrated, pointed bottom for moving hard soil or compacted sand, crushed stone, broken brick, reinforced concrete block parts, icy materials, etc. into the bucket. A brush, hooks, pitchforks, rakes, and other structures and mechanisms may also be attached.
[0038] In the stowed position, articulated levers 3 and 4 fold and are located in recess 2 on the rear wall of bucket 1 (Figs. 2, 4, 6, 8) and do not protrude below the bucket bottom. An additional hydraulic distributor with electromagnetic valves for operating the levers can be installed on the rear wall of the bucket, along with two hoses for supplying and draining oil and an electrical cable. The control panel can be installed anywhere in the driver's cab.
[0039] For a clearer understanding, the images on the figures are made as simple as possible.
[0040] 2. The device works as follows.
[0041] The bucket is lowered to the ground surface. Shovel 9, mounted on levers 3 and 4 at hinge joint 6, moves from behind the bucket via a hydraulic drive and is positioned on the surface in front of the bucket at a distance equal to the length of levers 3 and 4 with the extending part. Subsequently, moving toward the bucket via the hydraulic drive, it transfers materials into the bucket. The driver controls the levers from the control panel in the cab.
