Detailed explanation of the pictures

20175738 prh 17-08- 2017

Figures 1a-1c show a removable multifunctional bucket 100 in a working position 490 in a plowing position.

The bucket 100 can be made of edged and straight structural steel plates which are welded together. The plates used are, for example, ordinary structural steels, e.g. s355, s420 and s460, and their yield strength is e.g. 235-500 MPa.

Wear blades having a hardness of, for example, 400-550 HBW can be used on the lip plates 109 of the bucket 100 and the blades.

In addition, circular rods and material tubes may be used to make the components 100 to connect each other.

The width of the bucket 100 can be e.g. 1 to 4 m, length e.g., from one meter to more than two meters and volume e.g. less than one cubic meter to more than four cubic meters.

20175738 prh 17-08- 2017

The bucket 100 comprises a bucket body 102 which can be used to move or lift snow or goods to be plowed or loaded.

In addition, the bucket 100 comprises pivotable wing sections 104 for plowing.

Additionally, the bucket 100 comprises a back plate 106.

In addition, the bucket 100 comprises a securing member (s) for attaching the bucket 100 to the implement 490. The securing member is formed at the rear of the body 102 so that the bucket 100 can be removably secured to the implement 490 e.g., a front loader (front loader, 10).

The body 102 comprises a bottom plate 108.

A lip plate 109 may be attached to the leading edge of the base plate 108.

Further, the body 102 comprises cheek plates 110 attached to the base plate 108, which may be formed such that they are substantially perpendicular to the base plate 15 108.

A wing section 104 is attached to each cheek plate 110 so that the wing section 104 can pivot relative to an axis 105 attached to the end of the cheek plate 110.

The bucket 100 may comprise a hydraulic cylinder 107 mounted on a lever end for pivoting each wing section 104. Cylinders 107 may be located outside the cheekbones 110 as shown.

The wing section 104 may pivot so that in the loading position, each wing section 104 is pivoted substantially against its cylinder 107 such that the wing section 104 is flanked by its cheek plate 110.

When the wing sections 104 are rotated (opened) from the loading position, each wing section 104 is able to pivot relative to its axis 105 in FIG. 1a so that it is at an adjustable angle a with its cheek plate 110.

A reinforcement plate 118 may be attached to the outer surface of each cheek plate 110.

20175738 prh 17-08- 2017

The bucket 100 further comprises an opening and closing partition 112 formed between the cheekbones 110 shown in FIG. 1a closed.

The partition 112 may have the shape of a plate profile or a U profile.

By means of the partition 112, a separate bottom opening sand space 114 is formed inside the body 102, bounded by the partition 112, the cheek plates 510 and the rear plate 106 for storing sand.

Partition wall 112 may be configured to open and close by rotation (rotation) relative to axis 116.

The partition 112 may be attached to each structure formed by the cheek and reinforcement plate 110, 118 10 on an axis 116 mounted on a bearing bushing.

Further, the body 102 may comprise a housing part (housing structure) 117 formed to close the space between the baffle 112 and the base plate 102.

Instead of the housing part 117, a flat part can also be used.

In addition, the bucket 100 may comprise hydraulic cylinders 120 mounted on a lever end for pivoting the shaft 116. The cylinders 120 may be located outside the cheekbones 110, and at the same time the reinforcing panels 118, as shown.

Alternatively, the partition 112 may be moved by a hydraulic motor or a hydraulic rotator. The pivoting device may be located inside the cheek plates 110 of the bucket 100.

Alternatively, the baffle 112 may be a tilting sandbox, whereby the sandbox tin 126 would be located either on the bottom of the sandbox or on the body 102 of the bucket 100, and the rear of the sandbox would form a movable rear panel 106.

Alternatively, the partition 112 may be an up and down movable pattern which, after filling the bucket 100, would lower the sand from the rear of the bucket 100 when lowered.

The inner surface of each cheek plate 110, which is at the same time the inner surface of the body 102, may have a cheekpiece 111 against which the uppermost partition 112 settles when the sand compartment 114 is closed by the partition 112.

The lower partition wall 112 or its leading edge (upper edge) may rest against the base plate 102 when the sand chamber 114 is in turn opened.

20175738 prh 17-08- 2017

Further, the body 102 may comprise a roof plate 122 which forms the roof of a sand chamber 114. The roof panel 122 may be secured to the upper edges of the posterior and cheek panels 106, 110.

The inner surface of the roof panel 122 may have a lip portion 324 against which the partition 112 in its uppermost position 5 settles when the sand compartment 114 is closed.

Alternatively, the bucket 100 does not have a roof plate 122 but partitions above it.

Fig. 1c shows a bucket 100 without wing sections 104.

The figures do not show the roads, the hydraulic parts except the cylinders 107, 120 and the motor 128, and the attachment parts of the bucket 100, which can be attached to the lip plate 109 and the wing sections 104 10.

Fig. 1d shows a cross-sectional view A-A of the bucket 100 along the axis line of the partition 112 when the partition 112 is up.

The bottom of the sand chamber 114 may have a sanding section (grinder) 126 for spreading the sand in the sand chamber 114 15 or the entire bucket 100 from the bucket 100.

When using the sanding member 126, the sand flows to the sanding member 126.

The sanding member 126 may be, for example, a pendulum sander, a roller sander or a plate shaker. The pendulum bottom sander 126 has proven to be excellent in sand spreading when the bucket 100 is used as a plow simultaneously.

Depending on the model of the sanding member 126, the motor 128 driving it, e.g., a hydraulic motor, is located either in the sand chamber 114 or, as shown, outside the body 102 of the bucket 100.

The bucket 100 may have widened sand dosing to the pendulum base 127 by adding sand tunnel (s) 130 to each side of bucket 100, allowing for a wider sanding width.

Fig. 1e shows a sectional view A-A of the bucket 100 with the partition wall 112 up.

Fig. 2a shows a bucket 100 without blade members 104 in the loading position.

20175738 prh 17-08- 2017

The sanding section 126 is filled either by shoveling the sand pile or by dropping directly from the sand silo to the shovel 100. By scooping out the sand pile, loading is performed on the wings 104 against the cheek plates 110 of the bucket 100 and the partition 112 down against the bottom plate 108, as shown.

Generally, when filling the silo, partition 112 is only slightly opened so that the sand can enter directly into the sand chamber 114. The silo filling can also be performed on the bottom plate 108 of the bucket 100.

If it is desired to use the large sand space provided by the entire bucket 100, leave the partition 112 down and tilt the bucket 100 so that the sand flows into the sanding section 126 and does not drip from the bucket 100. The bucket 100 is then ready for sanding.

In the case of using a small sand chamber 114, the bucket 100 is turned over with the sand 15 almost filled with the partition wall 112, whereby some of the sand enters the sand chamber 114.

The partition 112, the cheekbones 111, the lip portion 324 of the roof 122 of the roof 122 of the sand compartment 114 and the housing section 117 on the base plate 108 form a compact sand compartment 114 where sand does not escape and the snow does not penetrate the sand compartment 114. off the bucket 100 by tipping.

The partition 112 may rotate steplessly on the shaft 116 from a lower position according to the loading position, with the partition 112 facing the bottom plate 108, fig.

a, in which the partition 112 is against the bevelled lip portion 324 of the roof 122 of the sand chamber 114.

Naturally, the partition 112 may pivot from its upper position back to its lower position.

The shaft structure for moving the partition 112 is simple, easy to replace and relatively inexpensive to manufacture. As a result, there are no extra parts on the inside surface of the bucket 100 and the cylinders 120 are adequately shielded on the side of the bucket but still easy to maintain. The partition 112 provides 30 mii ramps to the sand when using the entire bucket 100 as a sander and when closed, the bottom of the bucket 100 has maximum space for snow and the joint between the bottom and the partition 112 is smooth.

20175738 prh 17-08- 2017

Fig. 2b shows a cross-sectional view A-A of the bucket 100 from the axis line of the partition 112 when the partition 112 is down against the bottom plate 108 and the wing portions 104 against the cheek plates 110.

Fig. 2c shows a cross-sectional view A-A of the bucket 100 when the partition wall 112 is down.

The sand chamber 114 is emptied using either a sanding section 126 or by opening the partition 112 and tipping the bucket 100. In the latter way, a small amount of sand may remain in the sand compartment 114, which can be removed using the sanding section 126.

When sanding at the same time as plowing, a small sand space 114 is used and the partition wall 112 is closed in fig. 1a. In this case, it is also possible to load the snow with the bucket 100. Wing portions 104 are used in plowing in the same way as in other commercially available paddle shovels.

The bucket 100 allows immediate sanding after plowing.

The partition 112 is suitable for the width of the bucket 100 and e.g.

Partition wall 112 generally extends slightly below the top of the cheekbones 110 of bucket 100, so that the wall 112 seals the sand chamber 114. The height of the wall 112 from the bottom of bucket 100 may be, for example, 500-2000 mm.

Lowered, a tight joint is formed between the bottom plate 108 and the partition 112. Thus, the partition wall 112 acts as the plane along which the sand flows into the bucket 100 on the working machine

490 facing tilt to sanding section 126.

The partition 112 may be attached to the body 102 other than the cheek plates 110, e.g., the bottom plate 108 or the back plate 106 of the bucket 100, which may not require the supporting shaft 116 which simultaneously transmits the torque 25. In these solutions, the cylinder 120 or cylinder inside the bucket 100.

Partition wall 112 may be, for example, box-shaped or made of a single sheet. It is also possible to use round profiles and pipe beams in the section. The materials of manufacture may be, for example, structural steels s235, s355, s420 and s460, or wearable steels having, for example, 400-500 HBW hardness.

20175738 prh 17-08- 2017

The shaft 116 of the partition 112 connects the partition 112 to the body 102. The shaft 116 may be, for example, a pipe beam, a profile shaft, a profile tube or a rotary bar. The material may be, for example, s235 or s355 structural steel or alloyed shaft materials.

The torque required to rotate the partition 112 is provided e.g.

generally available on the market with lever-mounted hydraulic cylinders 120, a hydraulic pivoting device directly mounted on a shaft 116 or a hydraulic motor. The lever material may be, for example, ordinary structural steels or cast steels. The shaft 116 with its levers may also be molded.

The pendulum bottom sander 126 has a pendulum plate (bottom) 127, 10 at its bottom, which may be slightly narrower than the width of the bucket 100. It may be made of, for example, structural steels such as s235, s355, s420 and s460, or wear steels having, for example, 400-500 HBW hardness.

The pendulum plate 127 generally moves on two brackets secured to the back of the bucket 100 106. The pendulum plate 127 has either straight or oblique steel bars to facilitate sand scattering, and the opposite sides of the bucket 100 body 102. Against the straight pendulum ribs, the body has 102 tilted plates.

As the pendulum base 127 moves sideways, the straight-angled combination causes the sand to alternately fall from the front and back of the pendulum plate 127 to the ground.

The sand tunnel 130 (sandbox) is made to extend the power list of the pendulum plate 127 to the maximum width of the entire bucket 100 and may be positioned over the pendulum plate 127 on either side of the bucket 100 to achieve a wider sanding width. , structural steels such as s235, s355, s420 and s460, or wear steels which may have a hardness of e.g. 25,400-500 HBW.

The pendulum bottom sander 126 has a large sanding width compared to a roll sander, which can be almost the entire plowing width. In addition, it is less prone to sand interference than other types of sanders.

Figure 3 illustrates in more detail the lip portion 324 formed in the roof panel 122 against which the upper edge of the partition wall 112 rests when the sand compartment 114 is closed.

The roof 122 of the sand compartment 114 prevents the snow from mixing with the sand and plowing the sand over partition 112 on the other hand when the plow is plowed

20175738 prh 17-08- 2017 tessa. Roof panel 122 may have a bevelled lip portion 324 to seal partition 112 against roof panel 122. The lip lip 324 serves as a stiffener and reinforcement for the roof panel 122. Parts of roof 122 are made of, for example, structural steel sheets with a yield strength of e.g. 235-500 MPa.

Between the cheek plate 110 and the septum 112 on both sides of the bucket 100, a cheekpiece 111 is inserted. It is manufactured, for example, from structural steel sheets with a yield strength of e.g. 235-500 MPa. Tube beams or wear steel10 profiles and plates are also useful.

The bottom plate 108 may be shorter in the bucket 100 due to the sanding section

The required hole 126 in the bottom prevents it from being pushed to the back plate 106 of the bucket 100 in most cases. The bottom plate 108 may be bevelled upstream of the sanding member 126, which provides a space for the sanding member 126 to the bottom of the bucket 100 15. Between the bottom plate 108 and the partition wall 112 is mounted a bevelled housing portion 117 which seals the bottom plate 108 to the partition wall 112 and makes the rear of the snow compartment smooth. The parts may be made of, for example, s355, s420 s460 or s500 sheets or wear steel having a hardness of e.g. 400-500 HBW.

The cheek plates 110 and the reinforcing plates 118 stiffen the wall of the bucket 100 and provide a base 20 for the bearing bushing 112 which passes through and is welded to these plates 110, 118. The bearing sleeve material may be, for example, machine steels E420 or E470, or bearing housings machined into s355 or s420 structural steel plates.

The sanding member 126 may be driven by a hydraulic motor 128. An electric motor 25 ri is also a possible alternative. In pendulum bottom buckets 100, the rotary motion of the motor 128 is converted into a reciprocating motion on the eccentric plate. The pendulum base 127 can also be realized by a cylinder and valve system to automatically generate reciprocating motion. The hydraulic motor 128 is located outside the bucket 100 near the attachments of the working machine 490 for easy maintenance. The hydraulic motor 128 may be, for example, an engine having a rotational displacement of 100 to 500 cubic centimeters.

Fig. 4 shows a working machine 490 to which a bucket 100 shown in connection with the preceding figures is attached.

20175738 prh 17-08- 2017

The machine 490 can be, for example, a property maintenance machine, a front-mounted tractor or a property tractor, or a wheel loader

The bucket 100 is secured by its attachment member, e.g., to the front hoist 492 of the implement 490, and coupled to the control of the implement 490 such that the operator is able to control the bucket 100, blade portions 104 and baffle 112 using the controls

The bucket 100 allows two, or three, if big and small sanding properties to be separated, to combine the device into a single entity without significantly reducing any of the features. The wing snow bucket and sander can be remotely connected 100 to the same bucket.

Combining a wing snow bucket and a sander enables plowing and sanding at the same time.

In addition, sanding takes place in the driver's normal field of vision and not behind the machine, such as when working with rear lifting equipment. When plowing and sanding 15 are performed on the same pass, e.g., in a narrow space between cars, sanding can be performed either at the same time as plowing ahead or when reversing between cars. After plowing, the working machine 490 with the sanding machine in the rear lifting equipment has to be turned and reversed between the cars in order to perform sanding, thereby reducing the need for the bucket 100 to be withdrawn.

In addition, bucket 100 improves occupational ergonomics and safety.

If the area to be plowed and sanded is larger, plowing and acute sanding of places such as doorways, mailboxes, trash can can be done first, after which 25 sand can be retrieved and the area sanded without changing the bucket 100. Usually the same operator will perform the sanding after plowing, whereby several machines will need a second run for sanding.

Some housing companies require sanding immediately after plowing, on a sloping or slippery yard, which allows the bucket 100 to avoid the use of multiple implements or unnecessary tool change.

If necessary, a sanded surface is provided beneath the tires of the machine 490 to improve the movement of the machine 490 itself. This reduces the need for studs on machine tools 490.
