[Conventional technology]

From concrete mixer truck or concrete plant mixer to pouring place Various methods are used to transport concrete to the site, depending on the site conditions. It is being said. However, each of these methods has its own problems, especially when The reality is that there is no convenient method for pouring large amounts of concrete.

0003 For example, concrete pumps can be used for large-scale civil engineering works, but In the case of scale, it is inappropriate because it increases costs and does not allow for flexibility. small scale concrete The easiest way to carry out this work is to use a concrete mixer truck that is close to the pouring point, and from there. is a method of throwing in by shooting. However, this method can be applied to It is limited to areas where concrete mixer trucks can enter and exit, and it is not allowed to put it into high places. Can not. In addition, the concrete hopper is suspended by a tow truck and transported to the loading point. However, there is a method to open the hopper and pour it in. This method allows the worker to The tow truck operator must operate the hopper lever to open and close the hopper. In addition to the above, additional workers are required, and working with a hopper suspended by a tow truck is dangerous. Accompany. Of course, it cannot be used in areas where tow trucks cannot access. power show Heavy equipment such as a bell is used to drive the ball, and a traditional bucket is often used to drive the ball. However, it is difficult to adjust the amount of concrete poured and requires extremely skilled operation. It is necessary to prevent the concrete from scattering and contaminating the surrounding area when it is poured, and from causing the concrete to separate. There are problems such as easy deterioration of quality.

0004

[Problem that the idea aims to solve] The inventor of the present invention solved the above-mentioned problems, especially by making it easy to adjust the amount of concrete input. The challenges are that the quality control is easy, and the work can be done safely. , we considered the solution.

[0005]

[Means to solve the problem]

As a result of studies to solve the above-mentioned problems, the inventor of this invention found that the most commonly used In order to make use of power shovels, such as backhoes, which are commonly used in did. Then, we actually made a prototype front attachment bucket for that purpose. As a result of repeated research and improvements on its shape and on-site operability, this idea was completed. That's what I did.

[0006] That is, the first idea is to have an opening in the lower part of the bucket body, and A feature is that a partition door is installed in the hole to open and close the opening in a sliding manner. We provide buckets for power excavators.

[0007] Next, as a second invention, the power shovel bucket of the first invention and the above-mentioned The hydraulic cylinder that opens and closes the partition door and the hydraulic cylinder that is operated from the cab of the power excavator. A bucket device for a power shovel is provided, which includes a cylinder control means.

[0008]

[Action and Examples]

The present invention will be described in detail with reference to drawings showing embodiments.

[0009] FIG. 1 is a front view showing an embodiment of a bucket for a power shovel according to the first invention; FIG. 2 is a side view thereof.

0010 In this embodiment, a partition door 3 is provided with a slide guide in the opening 2 at the bottom of the bucket body 1. 4, so that the hole 2 can be opened and closed in a sliding manner using a hydraulic cylinder 5. It is being

In the present invention, the bucket body 1 has the function of a concrete container. Although its shape is not particularly limited, it is preferably a hopper shape in which the cross-sectional area is narrowed at the lower part as in this embodiment. This is because it is easy to accurately pour concrete into a predetermined pouring location, and the concrete in the bucket body 1 can be completely discharged. The shape of the cross section is preferably square, which makes it easy to attach the partition door 3 and is easy to manufacture. The shape and size of the opening 2 may be determined depending on the purpose of use. The opening 2 is located at the lower part (bottom) in order to completely drain the concrete. There is no particular limit to the size, but since the main purpose is to supply small amounts of concrete, a size of about 0.5 to 1.5 m ² is easy to use.

0012 The partition door 3 discharges and preserves the concrete in the bucket body 1 by opening and closing. It has the effect of holding. To open and close the partition door 3, slide it parallel to the wall of the opening 2. I will do it. The sliding type was adopted because the concrete can be poured depending on the opening of the partition door 3. The amount of input can be adjusted by adjusting the input speed and optionally closing the partition door 3 during input. This is because it can be done. The sliding direction is limited to vertical or horizontal directions. Alternatively, the image may be rotated around one point. However, it is usually not easy to operate or structurally. From there, slide it vertically in a straight line. Other methods, e.g. crossing the aperture plane The butterfly type, which opens by rotating in the opposite direction, has the same function as the sliding type mentioned above. This is not desirable because it is difficult to do so.

[0013] The shape of the partition door 3 is not limited to a flat plate. For example, insert the slide guide 4 into the opening 2. It is installed on the surface corresponding to the side wall, and the cross-sectional shape in the direction perpendicular to the sliding direction is U-shaped. It can also be bent into shapes.

[0014] The slide guide 4 holds the partition door 3 so that it can slide in a predetermined direction. It has a guiding effect.

[0015] In this embodiment, a hydraulic cylinder 5 is used as the means for opening and closing the partition door 3. There are also mechanical, electric, and manual types. But for safety reasons manual The formula is problematic. 6 is a hydraulic hose for operating the hydraulic cylinder 5; is a bucket pin for attaching the bucket body 1 to the arm.

[0016] Next, the second idea will be explained with reference to FIG. Figure 3 shows the second idea. 1 is a schematic diagram showing an embodiment of a bucket device for a power shovel.

[0017] Next, the second idea will be explained.

[0018] To use the bucket of the first invention by attaching it to a power shovel, the second invention is required. That is, in this embodiment, an operating lever 10 is provided in the driver's cab 9, and a known control means is used. For example, by operating a control valve (not shown) and using the hydraulic hose 6, It is preferable that the cutting door 3 is opened and closed by the hydraulic cylinder 5.

[0019] Most power excavators use hydraulics to operate the bucket. Since it uses hydraulic pressure for operation, it can be shared in some parts, is small, lightweight, and easy to manufacture. This is because it is easy to read and operate.

[0020] The hydraulic cylinder 5 is operated by an arm cylinder 12 for operating the arm 11 or a boom. An operating lever 10 provided in the driver's cab 9 similarly to the boom cylinder 14 for operating the boom cylinder 13. This is done from inside the driver's cabin using the . The work can be done independently from the driver's cab, so there is no need to worry about the driving location. It is labor-saving and safe because there is no need to approach the machine.

[0021] To explain a specific example of how to use it, first, close the partition door 3 and Concrete feeding equipment, such as buckets directly from the chute of a concrete mixer truck. Receive the concrete into the opening 2 of the bucket body 1 by operating the power shovel. Move the concrete to the specified driving location, open the partition door 3, and remove the concrete inside the bucket body 1. Enter You can open and close the partition door 3 to drive in multiple locations, and the bucket It is also possible to drive continuously while moving the main body 1.

[0022] In addition, the power shovel bucket of the present invention and its bucket device are It can also be conveniently used to input materials other than concrete, such as crushed stone.

[0023]

[Effect of the idea]

By using the power shovel bucket of this invention or its device, This means that workers are able to place the appropriate amount of concrete accurately in the designated location by themselves. Wear. There is no need for concrete stirring or kneading, and the concrete mixer truck is no longer required. It is now possible to carry out construction even on uneven ground or on soft ground, making it possible to improve the quality and capacity of construction work. can be significantly improved.

[0024] In addition, bucket operation can be performed independently from the safety of the operator's cabin, saving labor and ensuring safety. It can be seen as an improvement. In addition, this bucket can be used to load crushed stone for backfilling concrete. It can also be used efficiently, so you can use it in series without having to replace the front attachment. Concrete construction work is possible, and other work can be done using the easy front attachment method. You can easily change the work content by replacing the parts, improving work efficiency. death It also helps reduce costs since it does not use a tow truck.
