Abstract

PROBLEM TO BE SOLVED: To produce a lot of snow at a time in fruit trees and apple farmers in recent years, and it is not possible to use an existing snowplow to involve the branches in the work of digging up the side branches of the fruit trees buried in the snow. Snow is removed with a hydraulic excavator, but the claws of the excavator's bucket often catch the buried branches and damage them. Since it is not possible to grasp the depth position of the buried branches, it is a painful and inefficient snow removal work. SOLUTION: When the snow removal attachment of this hydraulic excavator is inserted from above the buried side branch, it is smoothly inserted into the snow, and when it hits the buried branch, the branch becomes resistance and cannot be inserted and is buried. You can remove the snow by picking up a lot of snow on the branches at a time and grasping the position of the branches. We provide a snow removal attachment that attaches to a hydraulic excavator that removes snow quickly, without damaging the branches buried in the snow during snow removal work.

Description

The present invention relates to a bucket for removing snow and removing snow with a hydraulic excavator.

When removing snow with a hydraulic excavator, the snow is scooped up with a bucket, and the snow in the scraping bucket is loaded into a carrier, dump truck, etc. to remove the snow.

In recent years, in fruit tree apple farmers, there is a lot of snow falling at one time, and the side branches of the fruit trees buried in the snow dig up the branches to prevent damage to the branches due to the weight of the snow, but existing snow removal machines are used to involve the branches. It cannot be used, and the snow accumulated on the side branches is removed by removing it with a hydraulic excavator, but the claws of the excavator bucket often catch the buried branches and damage them. Since it is not possible to grasp the location and depth of the buried branches, it is a difficult snow removal work with poor snow removal efficiency.

For house farmers, the snow that has slipped from the house and the house that collects under the eaves of the house is scooped up with a bucket of a small hydraulic excavator, and the snow is stored behind the hydraulic excavator. I was removing the snow that had accumulated in the meantime.

Also, in the orchard, when digging up a branch buried in snow, the snow accumulated on the upper part of the branch is carefully removed with a shovel etc. so as not to damage the branch. ..

Patent No. 6807967

This year, the amount of snow that accumulates in the orchards is different from the usual year, and the amount of snow that falls at one time is large, the branches of the fruit trees are buried, and the side branches are often damaged.

Snow accumulates on the side branches of fruit trees in the orchard, and if left buried, the accumulated snow melts day by day, increasing the density of the snow and causing it to sink.

Branches buried in snow become heavier as soon as the snow melts, cannot withstand the weight, and cracks from the roots of the side branches, leading to damage.

When a crack in the side branch of a fruit tree occurs, the subsequent harvest is hopeless and it is said that it will take four to five years to recover.

For this reason, snow removal work to dig up buried branches was indispensable, and it was not possible to remove snow around vast fruit trees by human power alone using a snow shovel.

We take measures such as spraying snow-melting agent before a large amount of snow is piled up, but since it snows after spraying, if it does not snow for a long time, the snow-melting agent has some effect, but it is a temporary snow removal work. I'm here.

To remove snow, a small hydraulic excavator was used to remove snow on buried branches.

I was removing snow while digging snow by inserting a bucket of hydraulic excavator into the snow on the buried branches.

You cannot tell how deep the branches are buried until you insert the bucket, and when removing the snow, the claws of the bucket scoop up the snow while entwining the branches, so the branches are also on the claws at the tip of the bucket. It was an unavoidable task of getting caught, involving the branches, and damaging the branches.

Snow removal excavation work is done so as to avoid the entanglement of branches by the bucket, but the depth of the buried branches is different from the depth buried in the fruit tree and the length of the branches, so the snow removal work while avoiding the buried branches Operates the bucket to determine the presence or absence of branches during excavation, relying on the operator's feelings.

Originally, a hydraulic excavator was excavated by inserting the claws of a bucket into the ground, and the earth and sand excavated in the bucket was shaky and held.

In order to avoid entanglement of branches when the bucket is shackled, the bucket attached to the arm is inverted and attached to scoop the snow on the branches, but due to the operation of the hydraulic excavator, the boom and arm Since the bucket was shaken back and forth greatly in the operation, the snow removal efficiency was poor and there were advantages and disadvantages.

Instead of utilizing the existing bucket mentioned above, remove the bucket attached to the tip of the arm of the hydraulic excavator, and attach a container that opens and closes the lower part of the snow removal storage container with a square shape to the tip of the removed arm, and the buried branch. Insert on top.

When the snow removal storage container is inserted into the snow and subsided, it can be seen that when it touches the buried branch, the branch becomes a resistance and the container does not sink any further.

At this time, if you narrow the bottom of the container that opens and closes, you can pick up the snow.

If the width of the square snow removal storage container is narrow, the snow can be grabbed and removed by pulling out the container with the snow pinched without installing a partition plate in the center, but the width of the storage container is wide. In the case of a large snow removal container, even if the opening is closed and narrowed to pinch the snow, the pinched snow will not be pulled out when it is pulled out, and only the container will be pulled out to the sky and the snow cannot be caught. It was not possible to make a snow removal storage container.

In addition, the snow that has accumulated snow contains a mixture of frozen layers and loose snow layers, and while the container is inserted and the snow is being pulled up with the snow pinched, the pinched snow breaks and the container is closed. It sometimes slipped off from the narrowed bottom.

Pinch the hard layer of the snow layer, apply pressure to the snow with moderate strength, grab it, and pull it out. There was a phenomenon that snow slipped off the storage container.

It was to excavate and narrow the lower part of the container to remove snow, but it has the above-mentioned drawback of removing snow, and in order to pick up and grab the snow, even if there is a force to lift the hydraulic excavator, it is a big snow removal. I couldn't make a snow shovel for the container.

When the square snow removal storage container that opens and closes at the bottom is enlarged, the snow cannot be grasped, and even if it is grasped, it slips off from the center of the opening and closing opening of the container. By processing the anti-slip and providing anti-slip members, etc., when the lower part of the container is inserted into the snow and the lower part of the container is closed, the snow is pressed against the central partition plate when it is closed, and it is gripped from the center of the container when it is pulled out. The phenomenon that the snow had slipped off is resolved.

When the container closes, it picks up the hard layer of the snow layer, applies pressure to the snow with moderate strength, grabs it, and pulls it out. It came off because it was broken, and the closing holding force that holds the snow loosened, and because it loosened, there was a phenomenon that the snow slipped off the container. A spring or pull spring is used as a holding member to prevent loosening of a closed container that grabs snow.

The holding member is designed to close the container further by the force stored in the spring when the grasped snow collapses and the closing force is released. By providing a push spring or a pull spring in the closing operation when opening and closing the container. When the closing force is loosened, the force stored in the spring is used as a member to prevent and hold the loosening.

Until now, the snow removal storage container that is inserted and pulled out is to be manufactured and used as an attachment for a hydraulic excavator. It was not possible to make it, but by installing a partition plate and a holding member in the center of the storage container, snow removal on the buried branches of the fruit tree can remove a lot of snow at once without damaging the buried branches. It is now possible to remove snow with a hydraulic excavator, and the snow removal work is quick. Also, this snow removal storage container utilizes the property that snow sticks to each other. By sticking to each other, it is possible to prevent it from slipping off, and it is also possible to remove only snow from obstacles buried in the snow, and it is also possible to remove only snow from buried branches and the ground and remove snow cleanly.

FIG. 12 shows the tip of the hydraulic excavator arm from which the bucket has been removed, and the snow removal attachment of the hydraulic excavator of the present invention is attached to the snow removal attachment of the present hydraulic excavator by utilizing the bucket mounting fixed shaft.

The snow removal storage container 1 is a square storage container, which is a pair of U-shaped left and right square containers made of steel plate or stainless steel plate. Part diagram of the storage container, which is a container that opens and closes at the bottom of the container, Fig. 26.27.28.33.

By moving one end of the upper part of the storage container up and down using the container support member 5, the lower part of the storage container 1 can be opened and closed.

The lower part of the snow remover storage container is a mechanism that opens and closes the lower part of the storage container by moving one end of the upper part of the storage container 1 up and down by moving the container support member 5 up and down the groove 7 provided in the container fixing column 2. Hold the knob, grab, etc. to store the snow in the storage container 1 (Figs. 6 to 11).

The drive unit that moves the container support member 5 that opens and closes the lower part of the snow removal storage container uses a hydraulic cylinder, an air slinder, a hydraulic motor that moves up and down wires, an air compressor, a winch that winds up the wires, and the like.

When the lower part of the storage container 1 is closed and the lower part is closed, the snow is pressed against the center of the container, and the snow is pushed and adhered to the non-slip partition plate 4 of the snow provided in the center.

The partition plate 4 is provided between the columns 2, and is provided in the center of the container. Members with holes and protrusions to prevent snow from slipping on both the front and back sides of the partition plate, expanded metal, non-woven felt, etc. are provided for snow. Fig. 13 to Fig. 29.30 shall be provided with a member to prevent the adhesion of felt and the slipping of snow.

When the container is closed, the snow inside the container is pushed and adheres to and adheres to the central partition plate, so that the container can be pulled up and snow can be removed while the snow is stored without falling from the closed container opening.

In addition, the inside of the container 1 is provided with protrusions and holes that appropriately stop slipping, expanded metal 10, and other objects that prevent snow from slipping.

When the lower part of the snow removal storage container 1 is closed, the snow in the storage container is pulled out in a pressed state, but sometimes when it is pulled out, the pressed and pressurized snow breaks and is about to spill from the lower part of the container. When the force of the spring stored in the pull spring or push spring of the holding member further closes the lower part of the container opening / closing part, pressure is applied to the snow to prevent it from falling.

A stainless steel push spring or pull spring is used as the holding member for which the closing force at the bottom of the container holding the snow loosens due to the breakage of the snow mass and prevents the snow from falling.

The snow removal attachment of the hydraulic excavator of the present invention can grab snow and remove snow.The existing bucket of the hydraulic excavator is removed, and the snow removal attachment of this hydraulic excavator is attached and used by inserting it into the accumulated snow. It can be grabbed and pulled out, and the snow in the snow removal storage container can be loaded by opening the lower part of the container on the loading platform of a carrier or dump truck.

It is used for general small hydraulic excavators, and it is described below as it is used for small hydraulic excavators with a bucket capacity of about 0.3 cubic meters. It may be slightly different.

Steel plates are mainly used as the material for each member of the snow removal attachment of the hydraulic excavator, but stainless steel or the like may also be used.

A pair of cono-shaped, 400 mm x 600 mm deep 120 mm square snow removal storage containers with a thickness of 2.3 mm, a width of 120 mm, a length of 1060 mm, and a position of 230 mm bent at a right angle of 90 degrees from both ends.

FIG. 33 is a container in which the lower part of the container opens and closes with a 12 mm bolt as a fulcrum axis and a 12 mm bolt is provided to fix the container with one point at the upper part of the overlapping portion as a fulcrum.

Figure 26.27.28 opens and closes the lower part of the container by moving one end of the upper part of the storage container up and down using the support member 5.

The container support member 5 is provided between the groove portion 7 of the storage container 1 and the support column member 2 and the storage container 1.

The column 2 to which the storage container 1 is attached is a member of a prismatic steel material, and a groove 7 is provided vertically at one end of the steel material column member 2.

The width of the groove 7 vertically provided at one end of the steel support member 2 is a groove in which the support member 5 fixing bolt 6 can move up and down, and the groove width is slightly wider than the bolt thickness of 12 mm.

The vertical length of the groove is such that the support member fixing bolt 6 can move up and down, and is formed as a groove having a length of about 105 mm.

The length of the groove varies depending on the size of the snow removal storage container 1 used.

The thickness of the vertically movable fixing bolt 6 used in the groove of the support member 5 is 12 mm.

The support member 5 is provided between the groove 7 and the upper end of the snow removal container 1. When the fixing bolt 6 of the support member 5 moves the groove up and down, the upper end of the snow removal container 1 is pushed down to push down the upper end of the storage container 1. It is a support member 5 for closing the lower part of the container with the fixing bolt 3 as a fulcrum.

The length of the support member 5 is about 210 mm, the thickness is 5 mm, the width is 30 mm, and the length between the fixing bolt 6 and the upper end of the snow removal container is 185 mm.

The partition plate 4 provided in the center of the square storage container 1 is a partition plate 4 provided with members for preventing snow from slipping off and adhering to snow on both the front and back surfaces, FIGS. 12 to 16, 34, 35.

The material of the partition plate 4 is a steel material or a stainless steel material provided between the columns 2, and the length inside the container is 600 mm, the width is 180 mm, the thickness is 5 mm, and the snow stored on both sides is prevented from slipping off from the lower part of the storage container 1. Fig. 29.30 is provided with square holes, protrusions, expanded metal, non-woven fabric of members to which snow adheres, felt, etc.

The partition plate 4 is provided in the center of the container so that the snow stored in the container does not fall, and may be a partition plate 4 in which the inside of the partition plate is provided at appropriate intervals such as round holes or square holes. 29, 30, 35.

In the state of the storage container 1 of FIG. 22, when the insertion storage container 1 is pushed into the snow covered with snow on the side branch of the fruit tree buried in the snow, the container sinks while the snow is cut into a square shape.

When the partition plate 4 in FIG. 22 is buried under the snow and hits a branch, the branch becomes a resistance and the snow removal storage container 1 does not sink.

The operator lowers the boom of the hydraulic excavator, pierces the snow removal storage container 1 and sinks it, but when the lower end of the storage container partition plate 4 hits the branch, resistance at the time of sinking appears on the arm tip and boom. The operator knows that there are branches under the snow.

At this time, the operation of the hydraulic lever that sinks further is stopped, and the lower part of the snow removal storage container 1 of FIG. 23 is closed.

By closing the bottom of the snow removal storage container 1, you can pick up and grab the snow inside the container.

When snow is caught in the storage container, the boom of the hydraulic excavator is raised and the storage container 1 is pulled up. Fig. 32.

Figure 19 when the bottom of the snow removal storage container is opened and the container for loading snow is opened by turning the hydraulic excavator around the snow caught in the storage container 1 and opening the lower end of the snow removal storage container on the loading platform of a carrier or dump truck.

Occasionally, the boom of the hydraulic excavator is lifted, and while the storage container 1 is being pulled up, the lower part of the pinched snow breaks due to the vibration of the hydraulic excavator, and the snow falls from the container.

In such a case, FIG. 21.24 is a snow storage holding member that further closes the lower part of the snow removal storage container 1 by the force stored in the push spring and the pull spring to further close the lower part of the container.

As the spring that stores the force to close the lower part of the container as the snow storage holding member, a stainless steel push spring and pull spring are used.

An air cylinder, a hydraulic cylinder, a wire winding witch, or the like is used for the operation of opening and closing the storage container 1.

When a cylinder is used to open and close the container, the holding member is provided with a push spring at the tip of the cylinder. Figure 24.36.37.38.

The cylinder is extended to grab the snow in the storage container and the lower part of the container is closed. At this time, the push spring provided at the tip of the cylinder contracts and the lower part of the container is closed. Figure 24.37.

When the snow that was held by closing the lower end of the container during pulling out or turning and loading work breaks and the snow stored from the lower end opening is about to slip off, the force of the push spring is released and the spring expands, opening the container. The push springs shown in FIGS. 23, 24, and 38 are holding members that can prevent the snow from falling from the container by further closing the part.

FIGS. 20, 21, 39, and 40 show that a pull spring is used for the snow storage holding member.

As shown in FIGS. 19 and 39, the pull spring of the holding member attached to the wire used for the opening / closing movable operation of the storage container 1 is pulled by the wire when the lower part of the container is closed, and the pull spring provided in parallel with the wire is also stretched and pulled. When the force is stored in the pull spring and the lower part of the container becomes loose, the force stored in the pull spring pulls the support member and the looseness of the wire when the lower part of the container closes is shown in FIGS. 21 and 40.

In the third embodiment, the members of the partition plate 4 provided between the columns 2 for fixing and mounting the storage container 1 will be described.

As shown in FIG. 34, the partition plate 4 is formed by welding and attaching the expanded metal 10 to the U-shaped member of the partition plate 4 by spot welding or semi-automatic welding.

FIG. 35 shows the partition plate 4 provided with a square hole 4-1 and is the snow-cutting portion 4-3 of the partition plate at the bottom of the partition plate.

When the storage container 1 is inserted into the accumulated snow and subsided, the snow is separated by the snow cutting part 4-3 at the lower end of the partition plate 4 and stored in the storage container 1, but when the container is lifted, the snow slides off from the storage container 1. To prevent this, close the storage container 1 while pressing the snow at the bottom.

When the container closes and holds down the snow, the snow is pushed from both sides of the container onto the central partition plate 4, and the snow adheres to each other through the expanded metal mesh. FIGS. 24 and 34.

Since the snow sandwiches the expanded metal 10 and adheres to each other, the snow stored from the center of the container does not slip off even if the snow storage container 1 is pulled out and lifted.

The nature of snow is utilized to prevent the snow that has been excavated and stored from the container from slipping off by utilizing the characteristic that snow sticks to each other.

It is FIG. 35 in which a square hole is provided in the partition plate 4 utilizing the property of snow described above.

Even if there is the power of a hydraulic excavator to be used for snow removal, until now, when a drilling storage container 1 with a wide container width was made, inserted into the snow and lifted, the snow caught from the center of the container collapsed and the snow fell, and the hydraulic pressure. No matter how much power the excavator had, it was impossible to make a large excavation snow container.

By using a member that utilizes the property that snow sticks to each other on the partition plate in the center of the container, the phenomenon of snow collapse and snow slipping off from the center of the container has been eliminated, and a wide range of snow removal excavation has become possible at once. ..

In the fourth embodiment, a spring is added to a hydraulic cylinder, a wire, etc. that expands and contracts to move the container support member 5 that opens and closes the lower part of the storage container 1 up and down, and the force during the movable movement of the support member is stored in the spring, and the container is made. It is described that when the pressure to hold down the snow at the time of closing is relaxed, the force of the stored spring is released to prevent and hold the loosening.

Figures 36 to 40 show a push spring added to the cylinder and a pull spring added to the wire.

The push spring and the pull spring are used as a holding member according to claim 5 to maintain and hold a force that keeps holding the pressure of holding the snow that closes the lower part of the container by the force stored in the spring.

Although it is shown in the figure as a holding member that keeps holding the snow stored in the snow removal storage container 1 with the pressure that the lower part of the container closes, a push spring that keeps holding the snow is provided between the lower end of the support member 5 and the storage container 1. Is also good.

As described above, a snow removal method in which the snow removal attachment of the hydraulic excavator of the present invention is attached to an existing hydraulic excavator and inserted into and pulled out from the snow, unlike the existing snow removal method, damages buried obstacles and causes damage. It is an attachment for snow removal of hydraulic excavators that does not have a snow removal method.
