Description

  The present invention relates to a drill-type core sampler that uses a core collection cylinder and is driven by a drill so as to dig a specimen sample in the cylinder, and more particularly, silage and other integration, agglomeration, or packing. Livestock feed [hereinafter, inspected livestock feed. ] About the drill type | formula core sampler for livestock feeds for extract | collecting the sample used as specimens for quality evaluation etc. Here, inspected livestock feed includes roughage such as hay and mixed feed (TMR) in addition to silage for storing live feed.

Conventionally, drill type core samplers for silage are known (see, for example, Non-Patent Documents 1 and 2), but no patent applications are found.

  In the above-described core sampler, a band saw blade (corresponding to a core bit) is attached in an opposite direction to the rotational direction at the insertion portion at the tip of an iron cylinder (corresponding to a core sampling cylinder).

  When this type of core sampler is applied to sampling of fibrous forage such as roll bale silage (same as wrapping silage), there is a problem that the rotation of the blade is hindered by the plant fiber and drilling excavation becomes difficult. It was. For this reason, there also existed a problem that the packing density of the feed digged in a cylinder became low.

  By the way, as part of measures to improve the food self-sufficiency ratio in Japan, the production of self-sufficient roughage has been promoted, and the storage method of these roughage has been changed to the wrapping silage method.

  Wrapping silage has a different chemical component composition for each field or roll, and the fluctuation in fermentation quality is particularly large. Therefore, confirmation of component values and fermentation quality is indispensable for wide-area distribution and feeding to livestock.

  In the future, when the production of self-contained roughage will expand, quality assessment by more appropriate sampling will be required, and improvement in the performance of the core sampler will be required. In addition to silage, versatility that can be applied to the inspection of roughage such as hay and mixed feed (TMR) is also required.

  Demand can be expected from research institutes related to animal husbandry and grassland, universities, extension offices, agricultural organizations, feed manufacturers, mixed feed (TMR) supply centers in various places, etc., which are considered as destinations of use, and this is also beneficial for industry.

  Under these circumstances, the present inventor has been engaged in research and development of rearing technology, and has proposed a highly accurate sampling procedure in wrapping silage (conference published); The present invention is one of the products of continuous research and development.

  The problem to be solved by the invention is to drill a hole even when the core sampling cylinder is rotated to the forward or reverse side by changing the cutting edge shape of the core bit when inspecting the chemical composition or fermentation quality of the livestock feed to be inspected. In addition to being configured to be capable of advanced driving, it is possible to cut a wrapping string such as vinyl or twain by a sharp blade surface, thereby enabling a predetermined amount of sampling at a target position.

  The present invention has been made in view of such circumstances, and provides an improved drill core sampler for livestock feed that solves the above-mentioned problems and enables efficient sampling from livestock feed to be inspected. is there.

In order to solve the problem, the present invention uses a core sampling cylinder and is driven by a drill to drill a specimen sample in the cylinder.
