Abstract

The invention relates to a hand-held foot-operated vertical compression soil sampler, which is used to collect soil analytic samples for soil formula detection and fertilization and is suitable for teaching, scientific research and production departments related with soil. The soil sampler contains a handle, drilling rods, a soil sample barrel and a pedal, wherein soil-unearthing ends of the soil sample barrel are symmetrically provided and connected with two drilling rods, the handle is positioned at one end of the two drilling rods, and a movable pedal is disposed between the two drilling rods. The soil sampler provided by the invention has a simple and reasonable structure, is convenient to operate, rotates flexibly, can be compressed into soil by means of auxiliary outside force, saves labor as well as time, and has high efficiency and the like.

Description

Hand-held foot-operated vertical compression soil sample barrel

Technical field

The present invention relates to a kind of drawing out soil equipment, a kind of specifically hand-held foot-operated vertical compression soil sample barrel, it is used to the collection soil analytic sample, carries out fertilization compositions based on earth measurement, is suitable for the teaching relevant with soil, scientific research and production division.

Background technology

Soil sample barrel is as a kind of collection soil analytic sample, and the aid that carries out fertilization compositions based on earth measurement is used by the teaching relevant with soil, scientific research and production division widely, soil sample barrel of the prior art; For example the patent No. is 92227022.8 patented claim formerly; 1., because its structure is unreasonable,, be in particular in: because the drill bit structure of soil sample barrel is thicker so there are many shortcoming and defect parts; So relatively more difficult during firming, the user is not easy to operate; 2., its handle is the handle arrangement of single pole, utensil rotates dumbly when for the sticking heavy soil of quality, fetching earth, and is difficult for fetching earth; 3., can not soil sample barrel be pressed in the soil by auxiliary external force such as pin, so operator's labour intensity is big.

Developed a new structure soil sample barrel in order to address the above problem the applicant, and applied for utility model patent, the patent No. is ZL200920094990.4; But the leading portion outside of also holding owing to fetching earth of this soil sample barrel during actual the use is the vertebral body structure shape; Wall is blocked up, and area is than excessive, and blade angle is excessive; Outer wall is big with the friction of hole wall when getting into the soil body, i.e. the resistance of soil sample barrel entering soil layer is big; Though the groove with the drilling rod clamping is arranged on two sides of pedal, take inconvenience in the use, be prone to lose.

Summary of the invention

The present invention seeks to provide a kind of resistance simple and reasonable, that soil sample barrel gets into soil layer little; Easy to operate, rotate flexibly, can soil sample barrel be pressed in the soil by the external force that pin helps; Pedal is difficult for losing, and is time saving and energy saving, the hand-held foot-operated vertical compression soil sample barrel that efficient is high.

The objective of the invention is to realize like this; This soil sample barrel comprises handle, drilling rod, soil sample barrel, pedal, and the unearthed end place of described soil sample barrel is symmetrical set and connects two drilling rods, and handle is arranged on an end of two drilling rods; Between two drilling rods, be provided with pedal movable up and down; Described soil sample barrel comprises the end that is unearthed, middle storage soil section, three parts of end that fetch earth, and described pedal is the rectangular structure of one or four jiaos of roundings, is symmetrily processed with the hole of suit drilling rod on the pedal; The said outside leading portion that fetches earth end is that right circular cylinder body, back segment are the centrum shape, and the inside of the end that fetches earth is the right circular cylinder body; Middle storage soil section is outside to be connected with end centrum shape one end that fetches earth, and the native intersegmental part of middle storage is connected through a rounding off section with the end right circular cylinder body that fetches earth, and the internal diameter of the end that fetches earth is less than the internal diameter of centre storage soil section.

The described end internal diameter that fetches earth is 34～42mm, and the internal diameter of middle storage soil section is 37～45 mm, the internal diameter of storage soil section in the middle of the internal diameter of the end that is unearthed equals, and the distance between two drilling rods is 100-120mm.

The present invention is owing to adopt said structure to reduce soil resistance; Be beneficial to pin soil sample barrel is stepped into soil, its soil sample barrel is more rationally convenient when fetching earth, and having overcome soil sample barrel in the prior art, to get into the resistance of soil layer big; Rotate dumb, firming effort; Fall the soil difficulty, can not soil sample barrel be pressed into the shortcoming and defect in the soil by auxiliary external such as pin, have simple and reasonable, pedal is difficult for losing, time saving and energy saving, the efficient advantages of higher; Be teaching, scientific research and the production division collection soil analytic sample relevant with soil, the first-selection of the carrying out fertilization compositions based on earth measurement utensil that fetches earth.

Embodiment

Shown in accompanying drawing 1: this soil sample barrel comprises handle 1, drilling rod 2, soil sample barrel 3, pedal 4; Unearthed end 5 places of described soil sample barrel 3 are symmetrical set and connect two drilling rods 2; Handle 1 is arranged on an end of two drilling rods 2, between two drilling rods 2, is provided with one and is enclosed within pedal 4 movable up and down on the drilling rod.

By accompanying drawing 1, shown in 2: described soil sample barrel 3 comprises the end 5 that is unearthed, middle

storage soil section

6,7 three parts of end that fetch earth, and the said outside leading portion that fetches earth end 7 is that right circular cylinder body, back segment are the centrum shape, and the inside of the end 7 that fetches earth is the right circular cylinder body; Middle storage soil section 6 is outside to be connected with end 7 centrum shapes one end that fetches earth, and middle storage soil section 6 is inner to be connected through a rounding off section with the end 7 right circular cylinder bodies that fetch earth, and fetches earth and holds 7 internal diameter to store up native section 6 internal diameter less than the centre.
