Description

The present invention relates to a hammer for a sampler. More specifically, the present invention relates to a hammer used to drive a pipe-shaped sampler into an object to be sampled.

A pipe-shaped sampler may be used to extract the sample from the powdered object to be collected. For example, in nickel smelting, a pipe-shaped sampler is inserted into a powdery raw material (nickel-cobalt mixed sulfide) packed in a flexible container bag to obtain an analysis sample. Hereinafter, the pipe-shaped sampler is referred to as a pipe sampler.

The raw materials in the flexible container bag tend to accumulate in the upper part for lighter small particles and in the lower part for heavier and larger particles due to handling such as filling, loading and unloading. Further, when the raw material contains water, the water content below tends to be high. Therefore, in order to obtain an average analytical sample, it is necessary to insert a pipe sampler from the top to the bottom of the flexible container bag.

However, the height of the flexible container bag is about 1 m. A pipe sampler with a length of more than 1 m must be inserted vertically into this flexible container bag until the tip reaches the bottom. The upper end of the pipe sampler at the beginning of insertion is in a high position, and it is difficult to hit it with a normal hammer (with a handle on the metal head), and the arm is very tired. In addition, it is easy to hit and the worker may be injured.

Therefore, a strut hammer may be used to insert the pipe sampler. As disclosed in Patent Document 1, the strut hammer is a bottomed cylindrical tool. Put the strut hammer on the top of the strut and move it up and down to hit the strut to drive the strut into the soil.

Utility Model Registration No. 3218282

Not all of the stanchions are driven into the soil, but only the tips are driven into the soil, with most of them exposed above the ground. Therefore, the strut hammer is not configured to drive all of the strut into the soil. In other words, the strut hammer itself that covers the top of the strut becomes an obstacle, and it is not possible to drive all of the strut into the soil.

On the other hand, the pipe sampler needs to be inserted almost entirely into the object to be collected. Therefore, after inserting the pipe sampler to some extent using a strut hammer, the strut hammer must be replaced with a normal hammer and the final several tens of centimeters must be driven. In this way, it is necessary to replace the tool, which complicates the work.

In view of the above circumstances, it is an object of the present invention to provide a sampler hammer capable of inserting almost the entire pipe sampler into an object to be sampled without replacing it with another tool.

The hammer for a sampler of the first invention includes a cylinder portion having a flat striking surface on the outer surface and a bottom portion for closing one end of the cylinder portion, and strikes the upper end of the pipe sampler inserted in the cylinder portion with the bottom portion. It is characterized in that it is possible to hit the upper end of the pipe sampler with the hitting surface.
The hammer for a sampler of the second invention is characterized in that, in the first invention, the tubular portion has a square tubular shape.
The hammer for a sampler of the third invention is characterized in that, in the first invention, the tubular portion comprises a square tubular striking cylinder and a cylindrical gripping cylinder connected to the striking cylinder.

According to the first invention, the pipe sampler can be driven into the object to be collected by sliding the hammer into which the pipe sampler is inserted up and down and hitting the pipe sampler. After that, by hitting the upper end of the pipe sampler with the hitting surface, the pipe sampler can be further driven into the object to be collected. Therefore, almost the entire pipe sampler can be inserted into the object to be sampled without replacing it with another tool.
According to the second invention, since the tubular portion has a simple shape, the hammer is strong and is not easily damaged.
According to the third invention, since there is a gripping cylinder in the cylinder portion, it is easy to hold the hammer when hitting the pipe sampler on the hitting surface.

Next, an embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
As shown in FIGS. 1A to 1D, the sampler hammer 1 (hereinafter, simply referred to as “hammer 1”) according to the first embodiment of the present invention has a cylinder portion 10 and a cylinder portion 10. It is composed of a bottom portion 20 that closes one end. That is, the hammer 1 is a bottomed tubular member.

The tubular portion 10 has a flat striking surface 11 on at least a part of its outer surface. Therefore, the tubular portion 10 may have, for example, a shape in which a part of the cylinder is flattened. The tubular portion 10 of the present embodiment has a square tubular shape. Since the tubular portion 10 has a simple shape, the hammer 1 is strong and is not easily damaged. In addition, it is easy to manufacture and maintain. The cross-sectional shape of the tubular portion 10 is not particularly limited, such as a triangle, a quadrangle, or a pentagon. However, from the viewpoint of ease of holding when driving the side surface and the size of the striking surface 11, which will be described later, it is preferable that the cross-sectional shape of the tubular portion 10 is a quadrangle as shown in FIG. 1 (C). When the cross-sectional shape of the tubular portion 10 is quadrangular, all four surfaces on all four sides are striking surfaces 11.

The dimensions of each part of the hammer 1 are not particularly limited. The width W is preferably 40 to 70 mm so that it can be easily held with one hand. The length L is preferably 200 to 300 mm. The thickness of the tubular portion 10 and the bottom portion 20 may be, for example, 4 to 5 mm, as long as the required strength and weight can be obtained, and depending on the material. The bottom portion 20 may be made thicker than the tubular portion 10 to adjust the weight. A certain amount of weight is required to hit the pipe sampler. The weight of the hammer 1 is preferably 2 to 3 kg.

Next, a method of driving a pipe sampler using the hammer 1 will be described.
The hammer 1 can drive a pipe sampler into an object to be collected by two methods, slide driving and side driving.

(Slide driving)
As shown in FIG. 2A, it is assumed that the pipe sampler P is driven vertically into the object to be collected packed in the flexible container bag. In the initial stage of driving, slide driving is performed. That is, the hammer 1 is put on the upper part of the pipe sampler P. The upper portion of the pipe sampler P is inserted into the tubular portion 10, and the upper end is in contact with the inner surface of the bottom portion 20. In this state, by sliding the hammer 1 up and down, the upper end of the pipe sampler P is hit by the bottom 20. As a result, the pipe sampler P is driven into the object to be collected.

(Side driving)
As shown in FIG. 2B, after the pipe sampler P is inserted to some extent into the object to be collected, side driving is performed. That is, the cylinder portion 10 is held by hand, the hammer 1 is swung down, and the hitting surface 11 hits the upper end of the pipe sampler P. As a result, the pipe sampler P is further driven into the object to be collected. In this way, almost the entire pipe sampler P can be inserted into the object to be sampled without replacing it with another tool.

[Second Embodiment]
As shown in FIGS. 3A to 3D, the sampler hammer 2 (hereinafter, simply referred to as “hammer 2”) according to the second embodiment of the present invention has a cylinder portion 10 and a cylinder portion 10. It is composed of a bottom portion 20 that closes one end.

The tubular portion 10 includes a square tubular striking cylinder 10A and a cylindrical gripping cylinder 10B connected to the striking cylinder 10A. The cross-sectional shape of the striking cylinder 10A is not particularly limited, such as a triangle, a quadrangle, or a pentagon. The flat surface of the striking cylinder 10A is the striking surface 11. The bottom portion 20 may be provided on the striking cylinder 10A or the gripping cylinder 10B. However, from the viewpoint of strength when driving from the side surface, it is preferable to provide the bottom portion 20 on the striking cylinder 10A. Further, since the upper end of the pipe sampler P may be caught on the connecting surface of the striking cylinder 10A and the gripping cylinder 10B during slide driving, it is preferable to provide the bottom portion 20 on the striking cylinder 10A in consideration of the workability of slide driving.

The hammer 2 of the present embodiment drives the pipe sampler P in the same manner as the hammer 1 of the first embodiment.

(Slide driving)
As shown in FIG. 4A, the hammer 2 into which the pipe sampler P is inserted is slid up and down to give a blow to the pipe sampler P. As a result, the pipe sampler P can be driven into the object to be collected.

(Side driving)
As shown in FIG. 4B, after the pipe sampler P is inserted to some extent into the object to be collected, side driving is performed. At this time, the gripping cylinder 10B is held by hand, and the hitting cylinder 10A hits the pipe sampler P. Since the cylindrical grip cylinder 10B is provided in the cylinder portion 10, it is easy to hold the hammer 2.
