[0001] The utility model relates to the field of agricultural engineering, in particular to bucket elevators with swinging buckets for moving bulk materials in horizontal and vertical directions [B65G 17 / 06; B65G 17 / 14; B65G 17 / 16; B65G 17 / 36; B65G 17 / 42].

[0002] A BULK MATERIAL ELEVATOR is known [RU 54922, published: 27.07.2006], comprising a head with a casing with a leading drum and a drive station installed in it, connected by prefabricated elevator pipes to a shoe with receiving noses and with a driven drum mounted in it, an endless belt with buckets, covering the leading and driven drums and placed in the elevator pipes, an explosion vent, an aspiration branch pipe, and the cylindrical surface of the leading and driven drum is made of plates, characterized in that the elevator pipes are made up of two box-shaped parts and have a rectangular cross-section, the bearing housing of the shaft of the leading drum is mounted on brackets rigidly attached to the side walls of the head, and the axis of the driven drum is mounted in bearing housings installed with the ability to move in vertical guides on the side walls of the shoe and having a Z-shaped profile,and the plates of the leading and driven drums are installed evenly across the diameter with a pitch of 1.3 V <S<1,6 В, где В - ширина пластины, S - шаг установки пластин.,

[0003] A BUCKET ELEVATOR (NORIA) FOR BULK MATERIALS is known [RU 201064, published: 25.11.2020], comprising a head with a drum connected by elevator pipes to a shoe in which a second drum is placed, a traction belt with buckets attached to it placed in the elevator pipes and a traction belt tensioning mechanism, characterized in that a tension drum is installed in the head, and a drive drum is placed in a shoe, wherein each drum is formed by a set of V-shaped ribs, the vertices of which are located on the plane of symmetry of the drum, perpendicular to the axis of rotation of the drum and directed in the direction of rotation of the drum with a pitch ensuring their mutual overlap, wherein the outer edges of the ribs form a barrel-shaped surface in contact with the traction belt, and the side surfaces of the ribs during rotation the drum in contact with the traction belt form inclined channels through which the seeds that have entered the drum are carried outside the drum by gravitational forces, in addition,In the central part of the drum, a support disk is installed on which the tops of the V-shaped ribs rest, and side disks can also be installed on the sides of the drum, on which the edges of the V-shaped ribs rest.

[0004] The closest analogue is the FADEEV NORI [RU 79281, published: 27.12.2008], containing at least one vertical elevator pipe, covering a conveyor with an endless traction element with buckets placed on it, characterized in that the vertical elevator pipe in the upper part turns into an inclined one, inclined at an angle α of 30 to 60° to the vertical.

[0005] The disadvantage of known prototypes and analogues is the impossibility of:

[0006] - simultaneous movement of bulk materials along a complex trajectory, in particular horizontal, vertical and inclined, in confined spaces;

[0007] - unloading of bulk materials at intermediate points along the route.

[0008] This utility model is aimed at eliminating the shortcomings of prototypes and analogues.

[0009] The technical result of the utility model consists in ensuring controlled selective unloading of bulk material during its transportation along a spatially complex closed trajectory.

[0010] The specified technical result is achieved in that the elevator, including an elevator pipe, a conveyor with an endless traction element and buckets placed on the conveyor, characterized in that a vibratory feeder is mounted with the elevator pipe, and unloading chutes are mounted on the horizontal sections of the elevator pipe, a closed-circuit conveyor is mounted inside the elevator pipe, driven by a drive, with the ability to move parallel to the adjacent vertical and horizontal edges of the elevator pipe, buckets are mounted on the conveyor, horizontally oriented and formed by the bottom and side walls, while the buckets are mounted on the conveyor pivotally with the ability to maintain their position when moving, for which purpose axles are mounted symmetrically to the left and right to the side walls of the buckets, the outer diameter of which corresponds to the inner diameter of the holes of the bearing brackets of the conveyor,inside the elevator pipe, on horizontal sections above the unloading chutes, bucket tipping mechanisms are mounted, containing arc-shaped skis and a movable platform mounted in hinges above the power cylinders with the possibility of vertical movement of the movable platform in the direction from the lower edge of the elevator pipe to its upper edge to ensure sliding contact of the convex sides of the arc-shaped skis with the pads and tipping of the buckets.

[0027] Implementation of a utility model.

[0028] The elevator includes a composite elevator pipe 1, made in the shape of a rectangular parallelepiped, a support base 2 with adjusting stops 3.

[0029] In various design versions, the elevator pipe 1 may have a Z-shaped (see Fig. 1, Fig. 2), U-shaped (see Fig. 3, Fig. 4) or zigzag (see Fig. 5) shape.

[0030] A vibrating feeder 4 is mounted in the lower part of the elevator with the elevator pipe 1, and unloading chutes 5 are mounted on the horizontal sections of the elevator pipe 1.

[0031] Inside the elevator pipe 1, along its adjacent edges, a closed-circle conveyor 6 is mounted with the ability to move parallel to the adjacent vertical and horizontal edges of the elevator pipe 1.

[0032] The conveyor 6 is made in the form of two endless traction elements, located mirror-image relative to each other, and is supported by drive 7 and driven 8 elements, made in the form of sprockets, and mounted on shafts 9 and axes 10, respectively, rotating in bearing supports 11. The movement of the conveyor 6 is ensured by transmitting rotational motion from the drive 12, made in the form of an electric motor, a gear motor, or in the form of an electric motor with an adjustable shaft rotation frequency, etc.

[0033] Between two endless traction elements of the conveyor 6, opposite each other, supporting brackets 13 with holes are mounted and connected to the endless traction elements of the conveyor 6 (see Fig. 8, Fig. 9).

[0034] Buckets 14 are pivotally mounted in the supporting brackets 13 with the ability to maintain their position when moving along a closed trajectory, for which purpose axles 15 are mounted symmetrically to the left and right on the side walls of the buckets 14, the outer diameter of which corresponds to the inner diameter of the openings of the supporting brackets 13. The buckets 14 are made horizontally oriented and are formed by a bottom and side walls.

[0035] On the side walls of the buckets 14, C-shaped pads 16 are rigidly mounted with one end, and with the other end they are directed towards the conveyor 6.

[0036] Inside the elevator pipe 1, on horizontal sections above the discharge chutes 5, mechanisms for tipping 17 buckets 14 are mounted (see Fig. 10, Fig. 11).

[0037] The tilting mechanism 17 of the buckets 14 comprises a movable platform 18 mounted in hinges 19 above the power cylinders 20. Hydraulic or pneumatic cylinders can be used as the power cylinders 20.

[0038] Arched skis 21 are mounted on the movable platform 18, with their convex sides facing upward. The movable platform 18 is mounted with the ability to move vertically in the direction from the lower edge of the elevator pipe 1 to the upper edge of the elevator pipe 1 to ensure simultaneous sliding contact of the convex sides of the arced skis 21 with the C-shaped pads 16 and tipping of the buckets 14.

[0039] Tensioners 22 of conveyor 6 are mounted on elevator pipe 1.

[0040] The vibratory feeder 4 contains an inclined chute 23, coupled with a filling device 24. A vibratory drive 25 is mounted under the inclined chute 23 (see Fig. 12).

[0041] The noria is used as follows.

[0042] A sleeve (not shown in Fig. 12) is mounted with a detachable connection to the inclined chute 23, through which the initial bulk material (grain, flour, compound feed, salt, granulated sugar, granulated or loose mineral fertilizers, lump coal, etc.) is fed to the bucket elevator. Due to the vibrations created by the vibration drive 25, the amplitude of which acts on the inclined chute 23, the bulk material enters the filling device 24 and is evenly distributed over the moving buckets 14, mounted between two endless traction elements of the conveyor 6.

[0043] The conveyor 6, together with the buckets 14, moves in a closed circle vertically and horizontally parallel to the adjacent vertical and horizontal edges of the elevator pipe 1, including along a complex trajectory specified in accordance with the design of the elevator pipe 1.

[0044] When the tipping mechanism 17 is in the lower position (see Fig. 10), the contact of the C-shaped pads 16 of the buckets 14 with the convex sides of the arc-shaped skis 21 does not occur and the buckets 14, together with the bulk material, move above the unloading chute 5 further along a closed trajectory.

[0045] To unload bulk material along the desired horizontal section of the transport route into the unloading chute 5, the power cylinders 20 are actuated by feeding liquid or air into them. The extending rods of the power cylinders 20 act on the rocker arms of the movable platform 18, mounted in hinges 19, and move the movable platform upward—from the lower edge of the elevator pipe 1 to the upper edge of the elevator pipe 1 (see Fig. 11).

[0046] After the movable platform 18 is raised, the upper points of the convex sides of the arc-shaped skis 21 are located above the lower points of the C-shaped pads 16 mounted on the buckets 14. The buckets 14 moving with the conveyor 6 run over the lower parts of the convex sides of the arc-shaped skis 21 with the lower parts of the C-shaped pads 16, sliding along them. Subsequently, with an increase in the friction angle between the arc-shaped skis 21 and the C-shaped pads 16, the buckets 14 turn in the direction opposite to the direction of movement of the conveyor 6. When the buckets 14 turn, the bulk material is poured out of them into the unloading chute 5.

[0047] The design of the elevator pipe 1 as a composite pipe in the shape of a rectangular parallelepiped allows for the placement of a conveyor 6 with buckets 14 in it and eliminates the impact of external factors, including wind, snow, rain, etc., on the bulk material being transported.

[0048] The presence of a supporting base 2 ensures the rigidity of the structure.

[0049] The presence of 3 adjusting stops allows for the alignment of the bucket elevator in horizontal and vertical planes during its installation.

[0050] The production of a Z-shaped, U-shaped or zigzag-shaped elevator pipe 1, depending on the customer's proposals, the complexity of the enterprise's process line and the layout of the enterprise's production facilities and workshops, ensures the ability to move bulk materials along a complex trajectory.

[0051] The presence of unloading chutes 5, located on the horizontal sections of the elevator pipe 1, allows the unloaded material to be directed to the desired process line for further transportation.

[0052] The presence of a vibrating feeder 4 in the lower part of the bucket elevator, containing an inclined chute 23, coupled with a filling device 24, and a vibrating drive 25, makes it possible not only to eliminate the formation of arches in the bulk material fed into the bucket elevator, but also to increase the uniformity of filling the buckets 14.

[0053] The installation inside the elevator pipe 1 along its adjacent edges of a closed-circle conveyor 6, made in the form of two endless traction elements located mirror-image relative to each other and supported by drive 7 and driven 8 elements, makes it possible to ensure not only the movement of the conveyor 6 parallel to the adjacent vertical and horizontal edges of the elevator pipe 1, but also the transportation of bulk materials along a complex trajectory and their unloading in various required horizontal sections of the movement route.

[0054] The presence of a drive 12, made in the form of an electric motor, a gear motor, or in the form of an electric motor with an adjustable shaft speed, etc., ensures not only the rotational movement of the drive elements 7 for the linear horizontal and vertical movement of the conveyor 6, but also ensures the movement of the conveyor 6 at the required linear speed, eliminating the pendulum swinging of the loaded buckets 14.

[0055] The presence of supporting brackets 13 between two endless traction elements of the conveyor 6 opposite each other, in the openings of which the axes 15 of the buckets 14 are pivotally located, ensures not only that the buckets 14 maintain their horizontally oriented position when moving along a complex closed trajectory, including when changing the vertical trajectory to a horizontal trajectory around the driven elements 8, but also the rotation of the buckets 14 along a circle when unloading bulk materials.

[0056] The presence of a tilting mechanism 17 above the unloading chute 5, on which arcuate skis 21 are mounted and with their convex side directed upwards towards the buckets 14, as well as the presence of C-shaped blocks 16 on the side walls of the buckets 14, makes it possible to ensure, at the right time, contact of the C-shaped blocks 16 with the arcuate skis 21 and rotation of the buckets 14 along a circle for unloading bulk materials into the unloading chute 5.

[0057] The presence of tensioners 22 will allow maintaining the required tension of the endless traction elements of the conveyor 6 and will prevent them from sagging when the buckets 14 are fully loaded. In addition, the required tension of the endless traction elements of the conveyor 6 will also prevent the buckets 14 from shifting in the horizontal and vertical planes and from falling out of the supporting brackets 13.

[0058] The use of the claimed utility model ensures controlled selective unloading of bulk material during its transportation along a spatially complex closed trajectory.
